First Passes on new Turbo setup

And wtf is with the car staging directly behind you!?

must have been in a hurry, the funny thing is, the car staging in the right lane stage with his back tires, that is why every one was yelling at him.

What was your best time with the procharger so I get an idea between the 2

So turbo with even less power equal faster car?

He also went manual to auto.

hp wise we are talking about a 9hp difference, and I don't think my F1 numbers were SAE, the 666rwhp are SAE numbers. The turbo power curve is much smoother than the F1. The F1 didn't start making power until the upper range of rpm, the turbo is a very nice curve. Going from the manual to auto also made/makes a huge difference.

What BMR k member do you use, do you think the forward facing headers would fit the 1/2 lowered one?

I have had the kmember for a while now, but I think it is this one.

it has the 1/2" lower mounts, but we did shim the motor up a little when we put the long tube headers on the car because they touched the steering shaft.

not bad for a shakedown. 9's are in your near future.

4r70w first gear is 2.84 vs the 3.22 first gear of the 5r55, so the 4.30 gear isnt a problem if its trapping at a good RPM keep the gear.

everyone thinks you need high gears (low numerically) with a turbo car. if the car is going through the traps at a good RPM and the turbo is spooling well there is NO reason to change the gearing.

and if needed a VERY small shot of n20 will make up for any spool issues.

point is gear for your trap speed not to "load" the turbo.

How is Sac for a track? I am thinking of going up there for the Oct 12th race.

I am willing to bet you money my car will trap higher and ET better with a 3.55 as opposed to the 4.10s. Its not all about loading the turbo in 1st. It has to do with how long you are able to keep the load as well. I shift to 2nd right around the 60' mark, that is hurting me bad!

Unlike popular belief you don't need a small shot of nitrous to help with spool - if your tuner is knowledgable he will pour timing on the down low - you can use timing just like nitrous and since it's a low load at the lower RPM it can take more - that's how I got my 12.2 car down to running a 10.66 with just givin it timing on the down low getting my 60ft down - If I would have kept picking at the tune I assume it would have went a 10.40
