Big Bore 3.2 to 3.8

It's a shame finding extra hp is so expensive for Boxster owners. $15,000 + installation and labor fees for 60 hp is Ferrari and a Lambo territory.

It goes with the Porsche territory. From the 50s until today. If you have a Porsche you pay to play.

I agree, but from a hp upgrade standpoint it's doubtful Boxster owners will drop $20,000 on an underwhelming hp bump. I hope I'm wrong and Jake makes out well. I guess time will tell if there is a market out there.

I've asked some of this before but it didn't get answered.

1.

My understanding is that engine designers produce dozens of sample engines and put them through simulations and real world trials involving millions of miles and still design and production defects exist.

You have mentioned a single trial mule car.

Can you tell us what testing you have done on the various configurations of engines you are offering? For example...has the 3.2 to 3.6 engine been specifically tested and how many and how much? Ditto the 2.7 to 3.0?

2.

Does use of the engine for a drivers education event (not racing, just driving fast on a track) void the warranty? Auto-X?

3.

Have you done anything to the sump? Deeper? Baffle changes?

4.

Do you have any locations yet for authorized installers since that seems to be a requirement for the warranty?

5.

And lastly, emission issues in a non-California state are a concern since my state does access the OBDII port and talks to their central computer in the state capitol before OKing the emissions every year. Has there been any emissions testings of the engines and what do you know about the non-CA legality?

Thanks for the postings and for the development work. Your approach is a valuable addition to the options available to those few who have problems or those many investigating and upgrade.

The X51 package can be replicated :-)

I know I want your 3.6L conversion with X51 3.6 heads and intake runners

Hey Patrick,

You may want to spec the more aggressive profile of the X51 cams too.

As a cost comparison, what does the 3.6l crate engine cost from Porsche? Without any of the labor of installation.

When I said "X51 heads," I meant as in populated, with the cams

Either way, when I get around to a swap it is likely going to be a "plain jane" 3.6 from Porsche, or one of Jake's conversions. The X51s are just too rare, and for a street car, I'm not paying the added premium, unless of course I come across a great deal on an X51 motor.

Hey Patrick,

Pople lated, my baad.

If I have to make the "Guardrail or Loggin Truck" decision someday, I'll have my widow contact you about a cheap X51.

Carry On,

Oh fantastic! Seriously though, for your benefit, I hope it never comes down to that.

Patrick

Jake- I seriously can't wait to see how this all winds up once its on the dyno.

JP, Unfortunately none of my cams will be optimum for what you are doing... This is mainly because we are not doing any super charging of the engines, only Turbo charging.

I have lots of reservations about setting up components in applications that they have not been proven in, especially with our program under such close scrutiny. we can't afford any complexities or even the possibilty of a failure.

I wish we could help, but your application is the only one we are currently not working with in some respect and I have no idea where we'd even start.

[Jake Raby]

we have several different cam grinds available, dependant upon your application and inended power band and rev range.

What must be established first is what you will be doing with the engine. Is it a torque beast or a high revver? What are you willing to do to the heads? What ECU manipulation are you willing to do? drive-ability comncerns?

Here we have no generic parts, everything is application specific.

3.6 with the IA supercharger running 4.5-5 lbs of boost. I only drive the car for fun on and off the track and it has never been nor will ever be a DD. I am willing to do the valve springs and the cams while the motor is out and my guy is willing to flow the heads but said more then likely not needed. I know that the 3.8 X51 has larger valves thus the guides would need to be increased but again my tech said it is not really needed. I already have the AASCO ligt weight flywheel for it and the tuning like my current package will be a one off. The current tune was done by Garret of GIAC. Stephen Kasper of IA will have the next one done. I am looking 400+ or - on pump of reliable HP.

I am being told that I can continue to run my 7.2 system with the 7.8 motor through the magic of tuning, but I am not holding my breath on that one.
