What kind of HP is practical form a stock 944S/87 with only exhaust and intake upgrades (legal)?

Jon Milledge is getting 209 bhp from IT legal 944S engines.

Is that crank or WHP? With 188 to start, I'd think you could get a tad more..

- exhaust header etc
- chipped ECU
- revised pre MAF intake
- blueprint

all legal I think.......

That would be at the crank. Custom header, MoTeC, etc. It's a full development engine. As Jake said, there just is not as much to be had. I didn't get into what limits the S engine. On the 8v engine it's the stock cam.

Jon does pretty heavy development on an engine brake dyno. While one might think there are standard gains to be made, that is not always the case.

Just a change here, Will the 944s2 ever be an IT car? I think it makes about 225 or just under at the flywheel. What does the BMW make compaired to weight? They are good dependable engines and cars so the money to race would be kept down just a little and could make for fun racing with the faster cars.

I don't speak for the entire ITAC by any means, but IMHO the car has too much power for ITS. If a class above ITS becomes reality, I think the S2 would certainly be up for consideration along with the 968. I personally would have a hard time endorsing it for ITS though.

I understand but help me out a little here. I have a line on a very good (rear end damaged) 944S and have found a 944S2 as well. What does the 944S2 make stock and what does the BMW make stock. I have considered selling the E production 944 car and building another IT car. Cost is a little high in production. I know I should do my own homework but you guys know IT way better than me.

If its only 10 hp difference bewteen the 944S and the 944S2 I would just skip any letters and fights that comes with getting something classed,if at all workable anyway.

A MoTeC is legal if it fits within the stock ECU (DME) box and the box still uses the same stock connector to connect to a stock wiring harness. This can and has been done with a number of cars including the 944S.

There are a lot of ideas floating around regarding how much of a diffrence the MoTeC makes vs a well developed set of maps on a chip in the stock board. According to Jon, the MoTeC is worth 4 hp over a good remap of the stock ECU.

Chris, I got that number directly from Jon in a discussion about the 944 and all it's NA variants. If this number is inaccurate I'm all ears.

That's crank on an engine brake dyno.

Both are very stout numbers. The non air box number especially. Generally, 18% is the accepted figure for driveline loss.

No calculator here, but thats about 37 HP, so both numbers are ahead of the curve, unless I am missing something.

Are you really trying to tell me you're getting 9 hp by eliminating the airbox? I'm having a very hard time believing that is real.
