 he mentions race gas. 36's won't get it done. I was in the 90% IDC range with the 60's with race gas on the 6.7 run.

And what change did it make when you changed to 80's.
Did you confirm the injectors were problematic?
Like I said before Mike went 10's on 37's. 
IDC is a theoretical number and can mean something is close to the end but not ''necessarily'' the injectors.
Race gas IS ''heavier'' than pump gas so the tune is different.
IMO of course.

Not sure about this one. Maybe with f/p set really low.

Nobody with a nearly stock turbo needs big injectors especially with alky spraying too.

Get some 60's and a chip from Eric and you're golden.

IDC dropped when I went to 80's. Nothing theoretical about it. 50's, 60's and 80's were new when I bought them. Anyone that knows me knows I always go above and beyond for fueling and going over every run on PL for anomalies. Eric mentioned on his website years ago that 60's and race gas would get you close to a mid 10 horsepower level. I have this habit of listening to the very best.

Injectors will go beyond 100%. That's what I mean when I say theoretical. people have run them up to 120% and more. 60's are good for about 720 hp and 80's are good for about 960 hp. How much quicker did you go with the 80's compared to the 60's.

37;s [SVO] will go 10's in a TR but I will agree it's not a good idea.

I know one Toronto member that went into the 9's on race gas and 83's that went over 100% and melted the engine down. My 6.7 run I was well into 90% IDC. I swapped to 80's in case I wanted to run quicker without engine damage. With the gazillions of runs I made, I never lost a set of head gaskets to a lean condition...an d it wasn't luck. Takes 680 to the back tire with a TR weighing in at 3500 on a 1.48 launch to crack the 9's.
