Thread: VE and Log Manifolds

nope, lets see, coheeds car made 441 on 25lbs of boost on a VE-T. My DE-T made 461 on 24 lbs. Equally sized turbo, both at the time were on basic tunes. Little did I know that I had a huge boost leak at my bov o-ring which is why my a/f was shitty and all over the place at the time. No recalibration needed. Then on 30 lbs after the intake manifold, throttle body, and boost leak fixed I know for a fact it was making insane power. 108mph trap speed in the 1/8th proved that one. lol. Again all on a DE-T.

As far as hood clearance, the cheap ebay manifold cleared the hood just fine with the 60 trim turbo, with the t67 i had to trim just a bit at the front hump that sits directly over the radiator support. Then with my new manifold that sat it even higher but clocked the housing more towards the engine, I had to trim a little bit more. My new manifold i just had made for my BW S400SX sits about 3" lower plus the turbine housing is a bit more compact than the old t3's i was using. Wider but sits lower. But we will see how well the clearance is with the massive compressor housing when I get it all fitted. I dont see there being any problems though.

im not going to read your book about your car.

you are comparing two different cars on two different dynos in your first sentence already

yes two different dynos, fact of the matter is, my numbers and my times match with my power outputs. So in fact my DE made just as much power and more than Coheeds VE-T on a log manifold. There is no doubting that even the cheap ebay tubular manifold will flow better than a log manifold. Its simple flow characteristics. Plain and simple. Then I put a larger runner equal length and nice smooth collector manifold on and im sure it did even better.

Log vs Tubular has been dynod back to back many many many times. No need to even argue the facts on the gains because they are proven. Huge gains. On large frame turbos we are talking 30-40+whp gains just from going to a tubular over a log.

Thought I'd leave this here.

Log manifold,On a 57mm turbo,60a/r .63 o2 stage 3 wheel.AGAIN not ideal manifold but gets the work done.
Could of made more but the ignition was breaking up and I did not feel like closing the gap on the plugs.
He runs this car like he stole it.

LoL

How many lbs?

You guys keep beating on this manifold thing.
500 has been made already on a stock motor with a log and a stock de motor with cams.
That figure is already more than what 80% of the people on this site would want anyways.
The only thing that keeps me from getting the 500 + is that I don't want to upgrade injectors.

Gio, noone is saying a log cant make power. Like you said, Its just not ideal nor efficient past a certain point.

You have proof a log can still make power. Nobody is doubting that.

Where did you dyno your car again? pheonix??

Yes, in phoenix.

Im sure there is a picture of my dyno chart floating around somewhere and you can see how jacked up my a/f is on it due to the unknown boost leak. Once i fixed that and dialed in the fuel pressure it was a night and day difference.
