Fuel pump replaced? No there was no reason to replace the pump?

A/f ratio was dead nuts for the 20 pulls on the dyno?


My redline is raised to 6400rpms but the car falls flat at 5800 and still shifts at 6400. So there is a 600rpm waste going into 2nd and 3rd too. I don't even have a CAI so the car just chokes hard at 5800. It goes from 350rwhp to 320 it falls flat. Hopefully the CAI gets it breathing better and the converter gets me in my powerband and keeps me there after shifts.

I didn't change the pump until I went to the cam/150 hit application. That was a dry kit btw.

I'm so ****ing tired of seeing posts about people running low 13's @ 104+

I need a car with real power so I could show you ******s how to drive it. 13.6@100 means I rock and you suck Dan.


oh..

and **** you for not selling me your Cobra like you pretty much promised in e-writing.

100-150 shot the goat after the stall and say hello to low 11's/high10's


I really doubt its the exhaust holding you back that much. I would point more to the cold air intake/throttle body/intake manifold then anything else

I would point at you for being ghey.

srsly








I just think it's the stall.

Idle video. Car definitely has more bark than bite right now. I am going back next week and I will manually shift the 1-2 & 2-3 shifts at 5800rpms and see if I can get the car down the track any quicker. I bet it works.

I think its the intake. My automatic GTO had LTs, no cats, flowmaster cat-back, KN Intake, dyno tune (350rwhp), and DRs. It went 12.85 at 108-109 on 1.8 60s like clockwork. My 2nd to 3rd seemed to be geared to far apart however. It would drop RPM too much on that shift. I had my shift pressure bumped up a good bit, which helped. I lost 2 tenths by changing the shift pressure back to stock levels.

There's a lot more in that car Dan. You just gotta get some air into that thing and get a stall to accomodate that cam so it leaves like it should.

Morbid Intentions

my plan with the LS2 is dropping a very mediocre sized cam in so I retain low end power and torque, stick with the stock stall, full bolt on's, 3.91 gears and a 75 shot

should have so much low end power and torque the stock stall will be high enough to shine

then later on drop the jets down to 25 shot and go for a centri blower... then I will have super low end power and the boost can pick up where the cam and spray dies off in the RPM range

sounds good in theory, I guess I will see

I think the problem is the LS1.. you need a 3valve in there.
