Lart... is it true you have parted dozens of 944s ? i wonder how many of the original 944 fleet are still running, at least on the weekends or at track events.

in any case, the only car i will be turbocharging anytime soon will be a Cayman as my second driver once my 968 is finished... my father is busy shopping for a Cayman on ebay... as far as the 944 turbo goes... you all know best.

Only parted what is in my signature barely 2 dozen

Mix and match your items if you want. If your wallet is fairly thick and you truly want the best...Vitesse is second to none. You could get a full Vitesse stage 2 or 3 car, run a worked N/A big valve head, CEP header and cross over...and 350 would be no problem. I've ridden in a 340-350whp Vitesse Stage 2 car. Very quick spooling car. No internal engine mods and around 17lbs of boost IIRC.

I'll be running a full Vitesse Stage 3 car. That's the turbo, MAF, piggyback, V-Flex and hopefully wasted spark too. The Vitesse stuff pulls a premimum for sure, but I can vouch that it's worth every damn cent.

"It costs money to go fast, how fast do you want to go?"...very true statement lol

a one vendor kit is perhaps the best option if you like that new part smell ... what ever that is .and realy want to part with 4 grand in a moment.
But if one was to get that pile of stuff from Ski then spend 2 grand on what ever they would be miles ahead of the "play it safe " one vendor guy ...

Good vendors such as Mike and John still support there customers if they have spent 4 grand on a kit or 200 on a single component .

As many have stated already, concentrate at the area under the power curve instead of a peak number. There are setups that give you peak numbers with terrible area under the curve (too much lag). There are setups that spoolup quickly, but cannot flow enough up top. To get something that spools up quickly and flows plenty to support plenty of HP up top is what you want (at least that's what I prefer and sell).
A fast 951 will have a different power curve than a dyno queen, even though the dyno queen might make higher peak HP number. You must look at it as a compete system, Turbo and engine management. Performance and reliability are both important! Reliability is very complex, you need the correct AFR and ignition, no matter what boost you run. You also need a system that will catch a problem and handle it properly to try and save your engine. Your engine management must do more than your basic fuel and ignition!
Of course I must say it: take a look at the V-FLEX software. You gain performance and if it saves your engine one single time, it pays for itself.

how the heck did you manage 21psi on 91?

lart951

well, I actually went up to 23psi and technically it was 91 octane, but I added 10% xylene.

By the way, I don't recommend building a car from bits from here and there, if I had to do it again I will go with one vendor and my choice will be Vittesse.

How are you running 21 psi on 91 oct. gas?

lart951

As I said before technically was 91 pump gas but added 10% xylene, the engine ran great.

V2Rocket

if i did the math right should be little over 93

Fast4525

Good real world point of view. What does the extra power really mean at the end of the day

What power numbers are owners seeing with a KKK K27/6 or K27/8? These turbos are cheap and should be simple to install. If 350whp is a lofty goal perhaps I should shoot for a strong 300+whp with a cheaper turbo?

lart951

is not only the turbo, you need chips, maf, afpr, injectors,wb, as I said before buying bits here and there does not usually give you the expected results, best thing is to get a package also don't forget about clutch because the stock one will usually give up after 300rwhp

Richgreenster

I have to laugh at this post or cry when I think about my own car and the money I've spent.

Once you start modifying these cars for more hp just plan on opening up your wallet because the modifications seem to never stop. Look a Georges car. Last I heard he was still spending $$$ on it.

These cars are just so addicting and fun to drive!!

curious lart what was the highest you ran normally on plain 91?

lart951

Same 21psi, the AFR was much richer than the one on the dyno chart I ran 11:4-11:7 max on 91pump gas no problem, see the attached graph, might not have been the most powerfull setup but it was safe.
