Stock block IX, FP Green, FP 4R. Stock BCS with #65 pill, Forge WGA

93oct V-Power & VP M1 Meth. 1050cc FIC (flow test @ 1100cc) + 500cc 1.0mm Meth Jet

Airflow in Lbs/min is measured (not estimated) using mrfred's airflow rate calc patch. Data corroborated with injector calculations here (injector size includes adjustment for 500cc of meth): http://rallyevo.com:8080/injectors.p...=12&max_idc=50

I estimate 430-440whp. Heading to the track tonight for trap speeds hopefully 122+mph.

 

you should think about getting a GM BCS, it would help with that taper.

 

Yea, I'm sure it will. How much more than 48 lb/min are people able to get out of the Green? I'd also consider a bigger turbo if I wasn't concerned about the stock bottom end.

 

i am pretty sure you are outside the turbo efficiency already so probably not much more.

 

Sorry, but how did you make these nice looks graphs?

 

Excel 2007

 

do you monitor EGTs at all?

 

No EGTs unfortunately. I would have logged AFR on this pull but my LC-1 sucks and doesn't always work. AFRs should be in the 12.5 - 12.0 range but I can't say for sure what they were here.

 

I would be a little nervous of your EGTs with they way you have the car tuned.

 

Too much boost?
Timing seems pretty aggresive, that should hold EGT´s within reasonable limits if A/F´s are correct.

 

It would definitely be good to know. I've been tuning in this way on this setup (minus the cams) for about a year now. I just replaced my plugs a couple weeks ago, and they looked very good... light browning and no deposits or deformation.

I definitely wouldn't run it this aggressive at any track other than the drag strip.

 

I dunno, it would just be soemthing to see at that aggressive of a tune. mid 12's plus that boost (on a turbo that may not be efficient at it) could equate to high EGTs.

 

That is why i wouldn't be incredibly worried. Should be fine for drag. Good luck at the track!

 

He already has the forge, and holding 25.5 psi at 7400 on a FPgreen looks to be pretty good to me.

 

looks like a stong car! GL @ the track!
