Bringing this back from the dead. Found something interesting I think applies. Basically there was a study done that shows there is VERY little difference between E50 and E85 on the anti-knock index. E50 tests out at 95.6 on the antiknock index. E85 tested out at 95.8. Lower ethanol blends...

You know that they say about those who assume.... ;) I never owned a buick chassis. Built an 86 rx-7 with a turbo buick Engine though... never knew about the IC fan. Thanks for the info.

Huh, I was told this was an IC fan off a grand national. Ah well, thanks.

Have one of these tack welded to a trans cooler. Bench tested it pushing and pulling. I can't tell a difference in flow. How are they setup from the factory? thanks!

Cool thread thanks! Basically confirms the links and info I posted above. Its an additive that’s gas station specific and or old additives ”gum” that has accumulated in old tanks that they filled with ethanol. It’s strange there is 6 pages on solid information from our friendly chemist. When...

4.8 short block all cleaned up and ready to go. Waiting on my degree wheel to arrive so I can double check the cam. Can't believe the amount of carbon and crap that builds up on these pistons. Cyls/bearings all looked great. Gapped rings to 20/24 and slapped everything back together. Takes...

I had been using photobucket for years so I have literally thousands of pictures on that site before they put a limit on the monthly bandwidth. I should change services lots of better ones out there, but all my millions of car pics are on photobucket. I joined on the 18th, so they should be up...

Actually aside from the "T" merge and the too large 2.5" piping... it is very easy to work on in the car. I can change all my plugs in 20 minutes (both sides) and I've never burnt a plug wire. Still running the original autozone LT1 set from 2 years ago on the pass side. I don't even run...

I have a build thread here with pics. Photobucket Nazis sold out (man I hate those bastards) and limit band width per month now. Mine is exceeded for this month so you'll have to wait till the 18th until all the pics are back up. My hotside is joke, so much so that I'm embarrassed to post the...

I do not. Just run a mech. gauge. I should also note that the last 2 oil changes I have noticed some alum flake in the filter element. I believe this is due to me uncovering the pickup on the launch. The F-body pan I'm using is horrible for drag racing. Even with me running 8qts (not a typo!)...

Managed to take out a head gasket on my motor, so I pulled the injectors. Oddly enough this year I have no traces of “goo”. My only theory is the 160lb injector tip design is less prone to producing the goo. I run no additives and all my gas comes from the same station that is very close to my...

New turbo is a worker! Trapped 159 tonight at 25lbs! Seems to be worth an additional 4mph or so over my last setup at the same boost levels. Still running the cheapo china IC as well. Ordered a treadstone unit to try. Pressure drop on treadstone cores is suppose to be much better. Best 60' of...

Thats ok for some i guess. But I cant idle 8 160lb injectors on pumpgas. And for a street strip car i dont want do drive around on a tank of low octane where i cant run boost! With toluene it actually raises the octane level so u can keep on boostin!

Just ordered 2 bottles, I'll let you know. FWIW I had some success with toluene. Toluene is pretty expensive here though so It's not something Id use all the time. pulled my #1 inj on my daily and verified it had "goo" on it, then reinstalled it. Then I ran my tank down to about 5 gallons and...

New turbo installed. :D Old turbo was a T4 1.10AR 83/74 exh wheel. 74.5mm cast compressor. New turbo is an T4 2.25AR 87/77.5 exh wheel. 76mm billet compressor.

Make that 155! DA was horrible 3700 ft! Hot humid air all night. Strapped the front end down and played with the ladder bars a bit. Bars were setup neutral without driver previously. Now I have them setup neutral with me in the car. (slip fit FWD mount bolt on pass side bar with driver.)...

If you read a bit, you would know "GOO" is region specific. Because you don't have the problem that does not mean you have done something correctly that we have not. "Misocnceptions"...? you mean Misinformation? What I stated were facts based on my personal experiences over many years dealing...

Bringing this one back. I've had first hand experience with the "Goo" for many years. Plenty of pictures as well. Ton of misinformation in this thread! That Lucas treatment appears to be nothing but petroleum distillates and dye on the MSDS? I have a hard time believing that will take care of...

My best last year was a 5.73 @ 122.7. If I could get this sucker to hook I'd be on my way to some 5.70's! If you all haven't seen this yet it, it blew my mind! Stock bottom end 5.3 Runs 4's in the 1/8th. 275 Dr's, Filled block on methanol. Aftermarket hardware on the bottom end. OEM rods...
