Just a guess, with the low 6.5comp and low .4 boost ... Im thinking around 250HP.

I would be happily surprised if its at the 300hp your thinking

Well, I'm actually not thinking 300 these days. I've changed my guess, is that allowed? Of course it is, this is my game. My new estimate with the Intercooler is around 280hp. 260 without it at .45bar. This is low boost after all. I do love my car though.

I've raised the boost to .8bar.
Who wants back in? Any guesses?

I've heard about the addiction to boost, and have had it with other cars but right now, with this car, I'm good with .8 bar. It's a lot and at the limit of adhesion anyway. Plus I don't want to pop this engine

I hate how Porsche guys measure in bar... its soooo annoying we get it your metric!

12 pounds on 6.5-1 is really nothing esp intercooling....Also I thought stock 930's ran 7-1?

For summer I would prop run lower boost anyways (esp with the ambient temps in vegas).

With a good intercooler setup (and esp if you get the wmi working) I think you could run 15-16 psi all day on that GT30 and be fine...just watch your IAT temps good indicator of when your risking knocking the motor to death without a knock sensor

Also your AFR is fine as long as you aren't geting pre-detonation, alot of guys like to run under 12 with knock sensors as a safe guard

Being that your out in Vegas AND I'm a Phx guy my suggestion to you to handle our high temps (unless you only wanna drive your car in the winter) is to go to E85! I converted on my turbo Saab some years ago... holy duck f***, my EGT's just dropped I was running 24 psi in the summer, intercooled only, and knock was nowhere to be found! and during the cool months I was able to get a lot of timing into that motor.

Now I had to upgrade the stock injectors because on pump gas I was at their limits anyways with my tune, and you need to flow roughly 30% more E85 than pump gas

It's not the HP that is spinning your tires, it's the torque.
The GT30 is smaller than a K27-7200 so spools quicker making more torque at lower RPM. A 3.3L (7.0:1 C/R) engine with the same mods you have will make 300WHP at stock boost level. Subtract 10% displacement loss and even money for the 1/2 point compression and 0.8bar and you have ~270WHP. My guess is that your putting down ~300ft/lb torque at the wheels. You should be able to run 1.0bar safely long term if detonation is eliminated.
I ran 315ft/lb torque through my 915 for about 8 years and could spin the 345's in 2nd. Watch the drag starts and you'll be OK.

Tonight I Smashed my friends cls550. I mean my car destroyed it. Not off the line though. Actually even with half throttle in first it did well and then second and full bark did him in. By the time third gear became nessissarry, there was no point. This is fun and it's 80 degrees out. Wonder what 30 or 40 degrees would give.
