I finished Rick's Boxster yesterday. Since he is only 75 miles away I took advantage of him being able to put the first 500 intermediate miles on the engine, following my 100 mile break in that I did yesterday. Once he racks up these miles, we will carry out the dyno sessions, and begin the ECU tune phase of the project.

This one is a pure animal. I'll let him describe to you in his own words how the engine transformed the car, and thats before any tuning, or optimization work has been carried out.

Here's some pics I took during my 100 mile run yesterday to break the engine in. The first pic is what we call "The Summit Photo". This signifies that we have reached the end of a project. This photo is what the owners of all my engines look forward to from the day that we begin the first stages of my process.

Very pleased with this one, as a Stage 3 Track Performer Plus.

Congratulations Rick,

Now you have a true One of a Kind car, reading Jake's description on an earlier post about having huge amounts of instant torque available, I can't help but comment that you may want to consider a nice LSD to compliment that engine (to help you to put the power to the ground..)

On my car the first big mod I made was adding a set of KWV's3 coilovers that I love but the real major change on the car was the addition of a OS Giken multi plate limited slip differential, it truly changes the behavior during heavy acceleration and braking, you will not be disappointed.. :)

I am sure that everyone is waiting to hear your comments of the new engine...

Nice photos! She's a real sleeper. Very tasteful exterior upgrades that gives little indication of what lurks below.

Holy......
 

.........crap!!!!


Dang you, Jake, I'm gonna start saving up now.

I can't thank you enough for the IMS and other preventative work you performed on my Boxster.

I'm gonna enjoy her for a few years before I have you build an engine for me.

At least, I think I will wait........:cheers:

Hey guys yesterday was an interesting day. I was not expecting Jake to call me to say the car could be picked up but I'm sure glad he did. I arrived at his place about 7:00 and it was 28 degrees out. We went over some cursory things and then it was time for the test drive. Jake drove first so he could go over how I should drive her and stuff like that. We were on a two lane typical mountain road with switchbacks, great curves, elevation changes so a good workout. First off the sound that this engine/header/muffler combo sends out is nothing short of amazing ! It literally sounds like a V12 Lambo or Ferrari........some low growl some high pitch whine with some raspy thrown in it is very hard to describe. But I can tell you I like it. It sounds like no other Porsche I have ever heard. OK so we reach a point in the road test where it's my turn. We swap seats and my heart is pounding and my hand a little shakey as I grab the shifter. The first thing I noticed as I launched for the first time is the INCREDIBLE throttle response I have never driven a car with crisp throttle response like this. It reminded me of my youth driving Yamaha twin cylinder 2 stroke street bikes.......instant throttle response. The next thing I notice is the torque/power she pulls like a freight train and revs freely. At no point did I ever floor the throttle but at 60-70 percent throttle she'd quickly rev to 7000 and gave no indication of letting up. I also soon realized that I was getting wheelspin in the first three gears, some of that attributed to cold tire temps, old Conti tires and the immense power of the engine. In one turn I hit the throttle a little too hard and she slowly stepped out but snapped right back in line with steering/throttle input. My nickname for her is " the beast " :D . Now keep in mind very little tuning has gone into this, as a matter of fact we're running a borrowed ECU from a 3.4 so it is far from being optimized but the ECU is learning/adapting very quickly. At one point in time while I was driving I got on it a little bit in gears 1 - 4 and Jake and I both burst out laughing this thing is a hoot ! I need to find a stretch of road and do a video/audio clip of this bad girl howling you guys won't believe the exhaust note. Yet at idle she's a mild mannered sleeper..........perfect ! So to say that I am happy or blown away or 1000% satisfied is an understatement . I can only imagine how much better it will be once we tune her up. And oh yeah what will happen when we swap the cams ? I'm not sure how much more I can take :p We ended up back at his facility and as we shook hands I said to Jake " so what do we do next year ? " . It seems like I'm doing some kind of deal every year with him. We started talking 3.8 intake manifold and a few more tricks up Jakes sleeve and I said OK that's enough for now. Let me enjoy " the beast " as she is and get to know her before we go to the next level. Besides I already have in waiting a H&R coil over setup waiting to be installed I want to lower her by an inch or so. I have the new wheels/tires to put on and I have some worn suspension arms that need to be replaced. Oh yeah I also need a new battery what's the best 950 -1000 CCA battery for the beast ? The 13:1 compression ratio is making my current battery wave the white flag :D

Yep. Thats exactly how it went.

The engine sounds every bit as good as the Flat 12 in my Testarossa... This combo never sounds like an M96, or even a Porsche.

Sounds like it is an exceedingly fun car to drive. An experience that tingles the senses? I'm very curious as to how it sounds based on the descriptions. Definitely not what I'd expected.

Jake,

If you use a 3.2 crank combined with 3.8 pistons, do you end with an over square 3.6 liter engine, that likes to rev and have a nice flat torque curve..? Thanks!

Regards,
Gilles

You could, and I do a lot... But thats become boring after doing it for a decade.. That combo is NOTHING like the beast that Rick has. Everything has been altered right down to the rod lengths, which were never used in any M96 engine from the factory.

I'm building one like this now with Titanium rods, my R51 heads, and 14:1 CR as well as my solid lifters, and tensioners. This one will easily spin 9,000 RPM and live.

i'm so jealous!

Jeez i am already yesterdays news i am an upgrade behind :D

Been watching this thread closely. It all sounds fantastic!

Don't worry about being behind a rev or two on Jake's list, you can't keep up, and you are already at the sharp end of a very pointy stick in a small group of people willing to step up and see the light, then watch most other cars disappear in the rear view mirror.

I'm not worried that's why I ended with the smiley face. Jake is like the computer industry constantly changing and evolving. I see by your signature line you have some Raby magic in your car. :cheers:

Like most people I'm curious on numbers (dyno) that is
Some threads are worthless with out pictures, well this thread is worthless with out numbers 😊😊😊

The time will come when we have numbers from the dyno. The dyno will not show the major attributes of this engine. I have 3 dynos in house and the first thing you learn the hard way is the dyno is not the be all, end all judge of performance.

The guys that think that it is, are the easiest ones to beat. They beat themselves.

Battery to buy.....
 

....What you want is an AGM battery.

Absorbed Glass Mat.

More power, can deep cycle, and does not require an exotic charger.

I installed this one in my Boxster:

NSB-AGM94R (L4) Battery****| NorthStar Battery

So far, I love it.

Yep, it is like saying money can't buy happiness but it sure helps

I understand a dyno is used to tune the engine on a controlled environment , and that it won't show some of the engine attributes like acceleration, driveability etc... But it sure helps

Btw no need for aggressiveness I have no idea what asking for dyno numbers has anything to do with anybody getting beat or beating themselves.
Tell me if dynos don't tell all why would you own 3

Did this battery fit the battery tray without modifications ? Did you purchase online or locally ? Thanks for the link .

The dyno has its place. The issue is most people have no idea how to read, or comprehend a dyno plot. When I hand a graph to someone and I watch their eyes go straight to peak power output, I shake my head and generally become disgusted immediately.

When my wife was Land Speed Racing her 996 the dyno kept her away from 3 records on two different occasions. I made changes to the car that I knew made it faster from the way it drove, and responded. The car LOST 6 HP at peak with these settings, but she smashed all those records in one weekend after that was done. They all still stand today.

I make more average power as an overall goal. Its really easy to make peak numbers, but increasing power at every RPM point is not a simple task.

Retaining drivability, longevity, reliability, and fuel economy while making more power is the big challenge. Rick will find that his MPG has increased by at least 3-4 MPG as long as he can keep his foot out of it, I have had some of these increase more than that.

+1 on AGM batteries. This is the one I put in my 2003 Boxster 3 years ago and it's great, and yes, it's a direct replacement and fits perfectly. I just disconnect the negative terminal and I can leave it for months without a trickle charger, and it doesn't discharge much at all. I left it for 1 month in December when it was -20° F for several nights in a row, and without a trickle charger it still had 12.8 V when I got home. Of course, be sure not to latch the hood (I remove the catch, two 10 mm head bolts, so it can't latch).

Exide Edge FP-AGML4/94R Automotive Battery - Battery Service Corporation

Joe B. funny you posted that link I was just looking at that exact same battery on Amazon but it was a little more money on Amazon. So thanks for the post !

When Jake and I first started talking about engine builds he was very up front that the engine would make great power but would be very drivable. This car is not my daily driver however I want it to be civil enough to be so if need be. I did not want to sacrifice daily driving comfort for peak horsepower just for bragging rights. To be honest I am just as curious to see the dyno figures as anyone else but I'm more curious to see the torque figures and at what rpm's . My butt dyno tells me the torque curve will have a nice linear curve because it is very strong from idle right up to 7000 rpm's that's as high as I have spun her being new. I'm also not planning on spinning her much past 7k anyway there just is no reason to do so. When I say she's a beast that is not to imply hard to drive or finicky she's a beast because of the power curve idle on up. Plus that exhaust sound ! In regards to Jakes comment about mpg's I don't see how I'll be able to keep my foot out of it :D

Battery fits perfectly.....
 

....Yes, this battery is a direct replacement for the OEM battery.

Plug and play.

Easy as pie.

I bought it from the factory directly from this web page:

NSB-AGM94R (L4) Battery****| NorthStar Battery

Highly recommended.

You are experiencing the all around higher average HP and Torque that I spoke about earlier in this thread.

To gain this takes more than bolting parts on, we have to machine them into submission, and set things up in a particular fashion. I can easily dial the lobe separation of those cams in differently, and radically effect the power band and torque curve without changing the first part.

Thats the difference between something thats truly developed, and "built", rather than something thats just bolted together.

I prefer "built" over "bought" any day.

I love this thread....keep it coming. It is almost better than sex. Jake, I think you are about to get a new build client.

I found a agm battery locally. Advance auto in house h7 agm with 1000 ca and 850 cca. They have an order online 15 % off discount with store pickup. After core refund out the door price 183.99 . I will pick it up tomorrow. Should be enough power to crank up the beast.

Advance has better deals than 15% off, although that may be what yours ended up with given how expensive the battery is.


Currently have $40 off $100 online TRT41

Oh well I have purchased the battery and will pick it up today. I had a online chat with a Advance Auto rep and asked who makes their batteries. Was told they are made by GNB or Johnson Controls. I can't friggen believe it since I have picked up the beast it has rained every day and last night it snowed !!! Tomorrow it is supposed to be sunny and near 50 so some miles will be added to the beast.

How about a sound clip for a pre and post tune comparison? I'm sure a lot of peeps would like to hear the beasts growl??? :)

911monty i am working on it. I just picked up the battery and installed it in the car. I have my maintainer on it right now . Got lucky the build date of the battery was december 2015. It is way too cold and icey out to do anything today. Hopefully tomorrow will be better. I hope to get a video and audio clip tomorrow.

I remember riding one of those bikes and doing a wheelie in 1st, and 2nd, and almost in 3rd gear. I then turned around and got off. I was convinced that I would kill myself riding a machine like that.

If that is what your engine feels like, all I can say is DAMN, I WANT ONE!

Yeah me too. Unfortunately will either have to move out of state or swap engines every 2 years..... So for now will have to live vicariously through sound clips and video.:ah:

Yeah my street bike riding started with a Yamaha DS7 which was a 250cc two stroke twin. Eventually moved up to a RD400 and that was quite a leap forward in power and speed. That 400 was very quick and if memory serves me correctly a 6 speed transmission. I remember one time tooling along at 100 mph when out of the blue the chain snapped..........and got wrapped around the rear sprocket and swingarm ! Rear wheel went from turning to NOT TURNING in an instant ! How it didn't throw me off is a mystery but I remember smelling burning rubber as I skidded a loooooong way to a stop. Rear tire had a flat spot that almost went bead to bead I was very lucky. But I was young and stupid and got back on her once it was fixed. And as luck would have it Jake currently has either a RD350 or 400 completely rebuilt for sale............I am fighting the urge big time :D

That's amazing.... I had an RD400 Daytona. Awesome bike at that time.

Not endorsing Advance as I tend to spread my buying around, but if you look at Slickdeals.net and search on Advance Auto Parts coupons or codes they are usually posted.

I got a Stant Thermostat assembly for a BMW E46 earlier this week at Advance for $38!

The line gets longer every week.... Added two more builds to the list this week :-)

I'd love to build something like this with 1bar of boost on it! Any plans to go turbo on the next one?

I have a boosted version of this, with all the internals developed. This includes valve train, valves, and camshafts.

BUT... The price tag that it has costs more than 5 Boxsters.

Guys I am still here and haven't driven the beast since parking it in my garage from when I picked her up :mad:. The weather has been crap, we had the grandchildren all last weekend so car playing was off the table :D Oh and there is this thing called work that tends to get in the way ! But I am off from work today and the weather is playing nice so first thing is to get her warmed up and on the lift so I can drain the break in oil. After that I plan on getting some miles on her. I will do my best to get some video/audio and post on here. I have never posted a video from my phone so I have to figure that out. I guess upload to Utube ?
