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!

Driven to and from track, build thread is here. http://www.turbobuick.com/forums/threads/1979-rx7-jy-ls-5-3-s400sx3-75mm-9-66-144-street-legal.398265/ Slower pass on the nice camera. Fighting traction with this thing! All vids should be in 1080p. Threw on some 29x12 slicks and still have...

Are Hyd. Lifters basically “pumped up” 100% during WOT operation? Could excessive oil pressure cause valve train issues on hyd lifters? Say 120+psi? First, this is a GM 5.3 LS motor, not a buick. Same rules apply I’d think. And I always come back to my buick crowd for basic engine information...

I'm working with master cyl. It has two ports off the dist. block for the front brakes and one to the back. I figured I'd use the back line to install the line lock, as it would be easier. I thought the line lock solenoid was just a simple ON/OFF valve. So instead of putting the line lock...

Is the official pace car writing on the doors of these cars under the clear coat? Or is it something easily removed? Thanks

Was told my cam drive was "bad" bought this new setup and replaced my old setup with it. Made no difference. Pulled it back out. Not even an hours run time on the cam drive unit. Used the caspers sensor a few times to setup base timing. Asking $125 shipped for the pair. LED cam sensor is...

So with my lights setup like this diagram. Low beam works great and is bright. When I switch to high beam All the lights come on but they are dim. The way I have it wired the high (top lights) should come on brightly and the bottom shouldn't come on at all. Some how I'm back feeding to all 4...

Just had the ECU checked by Bob a few months back. Car has been running fine since. Last weekend it started running rough. After a little trouble shooting I found the #1 injector was not firing. I'm getting full voltage at the plug. Noid light flickers just fine on the no.1 inj. lead. So I...

So I’ve read quite a bit on timing and boosted engines. It is constantly mentioned that the more boost you run, the less lead is required. It is then briefly explained that the added pressure in the CC causes the mixture to burn more quickly. I don’t see an explanation as to why it burns faster...

Upgrading to 95's. They are Delphi low-z injectors. Just pulled these off my about a year ago. They have been running great. I flowed them about 2 years ago. . They were spot on. Also have a fullthrottle speed.com extender chip, turbo tweak chip, reds pumpgas and reds race gas chip. $225 shipped.

Looking to step up into a Promod chassis. Asking $7500 for the car turn key as it sits. Car will come with matching Pro-star wheels as seen in last pic. Car has a clean FL title in my name. It is a salvage title. (theft recovery) Also may be interested in trades. Nice daily driver truck or...

I think I’m at the point where I’d make serious gains with a larger housing. Trapped 136mph with this one at 28psi. Let me know what you have. Looking only for buick 3-bolt style housings. I believe there is a .83 and precision makes a .85 for the 65 trim "P" wheel. Precisions .85 housing is...

Must be delphi's. I can get these new flow matched for $360. Let me know if you can beat that price significantly. thank you!

Upgrading to 95's. Just pulled these off my car. They have been running great. I flowed them about 2 years ago. They were spot on. Also have a fullthrottle speed.com extender chip I can substitute for the the turbo tweak. Looking for 225 shipped.

$20 plus shipping.

Think I'm floating valves with my current setup in sig. Around 28psi. Currently run 110# springs. Less than 50 miles on them. Car seems to break up at anything over 25 and get worse as boost rises. No knock. Really doubt it's plugs. I think I'm just runnign to much boost for my cam/boost...

I’ve been snooping around the small engine boards and keep running into huge power being made with very little timing and very high boost. I thought it odd I’ve never seen low timing and much over 20psi in the larger V6-V8 engine community, but it’s very common to see high timing and low boost...

(combo in sig) So after winter storage I had some issues with an injector not firing. Sent out the ECU to have driver replaced and the car starts up and idles and drives perfect. All scan master items in check. MAF readings are normal. Only CEL error is a code 23. Which I always have. I'm...
