HP, how much can a LIL 2.5L take? How do they Blow?

[pinzgo]

Hi Guys, Just to make up to date on my project. I own a Boxster S 2000 with 32000 miles on it. Last year I added Supercharger, catback, headers, ecu reflash by IA, Bigger injectors, air intake, lowered suspension, Put aerokit and full carbon trunk lid after spoiler and brake light, hard top, porsche seats with carbon shell, Kinesis wheels, Short shifter, carbon console,
This winter I am addind intercooler in trunk with fan onto lid, nitro sprayed on intercooler and progressive water methanol injection just prior to trottle body to refresh engine some more to higher psi. So,With these upgrades I will put smaller pulley on supercharger to get almost 7 psi at trottle body.

I hope I will dyno it around 375 whp. I do street and quarter mile drag with it in a team with my sons. They have a S2000 and a STI. Huge feeling.
Add comments or recommendations please.

I would like to send you pictures, but I need somebody of you to tell me how to insert in posts. I am not a pro with computer use.

I appreciate you guys with all infos contained in forums

Jacques,

I am glad you finally made it here.

You and I spoke via email back in May of last year when you where installing your supercharger. Glad to hear that you got everything running.

You seem like you are coming at this project very aggressively and I commend you for it.

If you look back at some conversations we have had on this board, you will see some of us have addressed what you are about to do. We would love to hear the details of the fan on the intercooler and I for one would love to hear about the NOS on the intercooler.

You jumped into a conversation about mething an intake and it seems like you may already have it worked out. Please post what you have planned because it will help a few Boxster owners out.

Midway through this thread you will see a link to another forum where this conversation is taking place also. there is some good info on that thread also.

If you have pictures if the car send them to me and I will post them.

PM me and I will give you my email address for the pictures. I am out of town and only have my cell for the web so I can not check my PM until Monday. (I see I have 3 of them so if you are one of them I will get back to you on Monday).

One last note, you will get better answers and more help if you start a new thread and not cross post the same message 2 or 3 times.

Make it a great night, we all want to hear about this project.

Jacque,

You’ve done good with your post. Add am image by uploading it to a place like this: http://img87.imageshack.us it will give you a URL in a couple different formats. One will be for forums. Just copy and paste it under the text of your post and push “preview post”. It probably won’t work. So just try some others (URL formats) till it previews O.K. Press “submit reply”. Your done.

Sounds like quite ambitious with your “S”. I’m doing similar with my 2.5, boosting from 4.5 psi to 6 or so. I don’t think my little Eaton blower will do much more with out spinning itself silly and/or taking up more hp to run it than it puts out. Haven’t done the math yet.

I’m doing just h20/meth injection. As far as I can tell it alone should do the trick. I thought a lot about IC and the trunk seemed Ideal but I didn’t feel like cutting holes in my trunk so it could breath.

Have fun, keep us posted,

PK

Hi Gary and guys, I had to work on myself to go ahead with putting intercooler in trunk. I am just going to do it. First, I had to remove soft top to clear the space on top of engine cover. Pipe will join the one coming out from supercharger, pass thru the cover and carpet with an elbow that will run straight thru the wall (Yes, over the engine cover) get into intercooler and come back the same way to catch the trottle body.It is about 3 more feet of (insulated with fire resistant) pipe. Intercooler is a two parts one that I plug together. Pipe is all 2.5 inches diameter. With actual supercharger intake tubing, there is no way to pass under the cover. It also means that soft top will not fit any more. I will add hump when I will remove hard top. If it rains away from my hard top, we will bring shampoo and sure get anough water to take a shower. But running with hard top is another feeling I like better than lowered top. It is like running a torpedo. NOS will be sprayed outside intercooler only. The mechanic that has the right !!! to touch my car was member of ROLEX porsche racing team. He is my advisor. He recommends not to inject nitro into that type of highly engineered engine. Water methanol is more adequate to lower temperature, higher boost and save engine. That way, the trunk wall has a good access away from ECU and car tubing and wires. NOS and W/methanol will all be in trunk. Do not ask why I do so much on a boxster. I love the car, the shape, it's personnality and so on. It is my toy. Upgrading to 911 or so on does not tell me anything. If we look a boxster coming on the road, It looks like a smile !!!

Good night everybody, take care
Jacques

Just for a test. I followed instructions

[pk2]

Update: Pieces are starting to come together. Got new SMT6 AIC (anyone tuned one). Waiting on a water/meth. Tank. Got all the tuning gear, EGT, wide band with laptop interface and data logging etc. Found a deal I think on pulleys, think I’m going to up 2 more psi or 30-35hp.

Not sure how I’m going to handle tunning while juggling timing, w/i injection & and a/f at once.

I assumed you had been busy with the car, we haven't heard anything in a few days.

I uploaded a picture of my temporary gauge cluster the other day on out intercooler thread. Boxster intercooler???....

My next phase...
Cat delete!!
I am deleteing my only pair of cats and install a set of electronic cutouts for the exhaust. I will be able to run almost complete straight pipes or quiet it down for long trips or that cell phone rings.

The only question I still have is weather or not I will run the cutouts via boost or a switch.

With this mod Turbowerx feels I will getter faster spool and possibly a little more boost.
The exhaust mods may be 45 - 60 days away it all depends on my mechanics schedule.

Hey Gary,

Cats eh? Is that a significant bottle neck in the system? It seems like there isn’t much in the exhaust system to change that buys you much except peace of sound. I’ve been looking for electric bypasses for quite awhile myself. I was only going to do it for sound (ala Pedro sport exhaust) if it was cheap and easy. It’s easy but not terribly cheap.

Have to be really careful out here screwing with emissions, every 2 years It’s a real nail biter. When my time comes up again I’ll be posting looking for clueless smog stations in So. Cal.

Right now I’m trying to sort out this AIC. Nice. versatile piece of work, but for the versatility you’ve got figure what you have. I.E. theirs 8 different ways a car can send an rpm signal x dozens of variations on each of those. Then comes the tunning…
