those are some nice numbers! yeah, nothing worse than a dyno day gone sour...


I think my next tune is going to be at Ivey's new shop as well... I frequently come up to Jersey to visit family.

Yeah for the conditions and the fact it wasnt even complete and made those numbers, I was happy. I dont boast about them because I'd rather go back since its already tuned now to just to do 3 nice pulls (with a real fan on the IC) when its not 90-100* out!

I put something together real quick here. Edit> For those not familiar with AEM logs, time index 4:15 is the top of third gear (Solid white marker), 4:17 is boost peak in 4th (no marker), and 4:20 is the top of 4th with it's respective marker.


Please, I just wanna know what exactly you mean when you write, "crankwalked turbo"? Sorry to hear about the bearing problems with your 20G-LT, man!
It's in reference to the 2Gs crankwalking (ah, the good ol days), which was a thrust bearing failure.

Wow, I'm only running 23 psi to redline(using the HP wastegate only, no boost controler) and my car is pulling really hard, with very minimal timing. I wonder what it will do on 110 @ 26 psi. any advice on what's the best psi on 11o leaded?

I know Bryan (Razorlab) runs 26psi tapering to 23 on his 100 octane street tune. I think he runs 23psi on his track tune IIRC.

kevin, thanks for that but where is the actual boost #?

Egine load = boost pressure.

Can anybody give me some insight. I have a 2.3 stroker all the bolts ons. Will I have boost creep with the FP upgraded actuator 18psi if i will be running 20-23psi max on pump. And will the MBC be able to help with this issue

The EVO green shows no signs of boost creeping. The actuator and MBC have nothing to do with boost creep however. The upgraded actuator has been shown to provide something of a boost "hump" which can be worrisome for some people, but with a stroker overall boost numbers will be low enough that it should be a non-issue IMO.

Quick question for you guys I just ordered my fp kit and I wanted to run 104oct looking to make 425-450whp, car already makes 350whp on stock IX turbo and 104@24psi. Im also adding cams and a big intercooler. I was told that for pump gas the stock injectors were fine but for race fuel I should use at least 680cc. What injectors are you guys using for race gas set ups thanks.

Denso 720cc is almost maxed out holding 23-24psi at 7k on my personal Evo so you might want to go bigger if you want some room.

This turbo maxed out at 49.1 lbs/min on my car. Using an average specific gravity for most race fuels of .72, target AFR of 12:1, and base fuel pressure of 43 psi, 650s will be at 99-100% IDC at most, regardless of boost pressure or mods. The x80 injectors always seem to end up flowing like x50 injectors, so 680s and 650s are effectively the same thing. So 720+ seems to be a good suggestion.
