What turbo are you running? I can't see you making that much power on the vf at 16 psi on 91. nice numbers though. I have a similar setup with only bigger TMIC and was just curious.

At peak power he's around 14-15psi. Just like all the other VF turbo's that are running "22psi!!11!!!". Phatron and Jr did this experiment not too long ago. Results are exactly as you see here. 22psi tapering to 14psi makes more peak torque, but similar peak power to a turbo that is 16psi tapering to 14psi.

yepppp...dont need a ton of boost to make power, sometimes more boost means more heat and isn't helping you at all. car makes great power and i love it, the drivability of this car is unreal.

Did you have a link to that?

There are various VF tuning theories, especially to keep them from tapering up so miserablely on 2.5's, but I can't find anything!

This has nothing to do with stopping the taper, simply that you don't need a lot of peak boost to make power. All you need is about 15psi @ 5k-6k rpm's and you'll make good power. Here are the links.

The first is the HP curves from the dyno and the second is the logs from the dyno in Virtual Dyno (to see TQ and boost). Junior tuned one with a normal (22psi) curve, and the other with a purposely low boost that didn't spool until very late. He was just trying to prove a point.

In the case of besthaticouldo's tune, the reduced peak boost will give a much more linear power response and flatter torque curve. It will pull more smoothly and still have just as much top end as any other VF. I would have gone for more peak boost (because that's fun ), but this tune is probably a very nice one for drive-ability.

Very interesting stuffs! Still looking into how to stop the taper of power to hold a gear out for longer and having it make sense!

See my posts above. Peak boost gives you high peak torque numbers. Boost at peak power is similar on this car as it is on most "22psi" VF setups.

I think hes running like 84.5 octane so 16psi is the most he could get without knock. (sarcasm lol)

I am not sure where this boost was measured, pre or post FMIC.... would you believe the graph if he told you it was 17psi?

I will agree with this. If you want to post and discuss your own results you can make your own thread. Please try not to derail someone else's "bragging" thread with your own data unless they've asked for it. Thanks.

rofl! it is what it is, the power is what it's making, the boost is 16psi. idk what else to tell you.

Let me correct myself. I see 16.4 on the dyno graph. However, the dyno numbers are irrelevant IMO without baseline numbers. That's what I was really getting at.

same dyno, 8 months ago i made 306whp/336wtq on 19.5 psi on a stageII protune (intake, dp, CBE, 3port) not tuned by tim, that tune sucked.

It's called a bigger turbo the little stock compressor wheel can only flow so much.

Correct me if im wrong, but those graph are from E85? We are talking 91 oct. I get the point but noty necessarily a fair match up.

Should not make much difference if you are only boosting 16 psi. The benefit of E85 is that you can run more boost without detonation. The point is that VF turbos are not big enough to flow high pressure at high RPM, it is like trying to go fast on a single speed bike.
