all on 93 Unleaded

Why? Might try running it a little cooler. May find a little ET. Mine likes to leave about 90 degrees.

For Mufflers..I like Spintech the best ..

Enjoy that my ears are not ringing at the end of the day.!

BTW my car still has working AC and love cooling down a bit after a run

Ed:
Are you running racing fuel ?

I might experiment with the lower temps. Not sure how it will work with a 9 to 1 engine on unleaded pump gas.
Alot of the reason I run at those temps are for round robin (consistency) purposes. Easier to get the water temp down to 160 than it is 90 degrees between rounds.

I'm still using the OEM computer and sensors even tho the IHRA rulebook does not say a racer cannot run an aftermarket ECM. ( if I read that correctly)
All I did on my car was set the dizzy and leave out the spout connector so the timing is locked @ 32 deg.

When I was still driving mine on the street on pump gas, it was still quicker cooled down.
That GM car has a plug-in chip. Uses the stock ECM. I can/have made stock looking chips for limited classes that don't allow chips. LOL

the tbi engine such as 305 can run with the timing connector unplugged to run at a base timing too. unlpug it and set the timing to 32-34 at the track, set back to 0-4 and plug in for the drive home

Chris1529 · 03-22-2013, 07:49 AM

do those cars have an adjustable fuel pressure regulator on them?

You can, but it then runs in "Backup Fuel Mode". I don't know what the WOT air/fuel ratio would be then.

"Do they have adjustable fuel pressure regulators?"

No, but they can be made adjustable.

Sure crude-azzed ways to try to tune one. Lmao!

Got headers and mufflers on yesterday and going to change oil to synthetic. Hopefully this will pick me up some.

my 88 monte ss is retired from pure stock but still will run 8.7s all day let me know how your coming out. that tbi motor runs way lean to begin with(hope you got a better fpr). I put one on my 87 suburban and it ran a lot better 3800lbs 10.30 1/8 mile and 20 mpg with 3.08's.
