This is Eric's car, one of our technicians here.

It ran at Dragging Rights this last weekend and at World Cup Finals at MIR the weekend before.

It will have a big bore forged engine for RS next year.





The only video of the passes are on his Facebook page and I cannot link them to the public.

I have all the videos of his passes from MIR: 9.14 9.04 9.007 9.04

I did go 134 on wastegate alone this weekend in Matt's car. That is 13 psi and 3350 race weight. Not bad, and only the beginning.

sorry guys, no laws or rules for the list. if the cnverter was locked thts fine, its just like a 6speed car isnt it??? and if the numbers are inflated then so be it, if u think theyre inflated, then u know ur closer to the same level. I can say my 5.3 makes 1500, but if u know it only makes 600, than whats the matter?

Technically 996 is the record. Locked or unlocked it is still the highest dyno numbers a 5.3 has seen

What year 5.3's is everyone using? I've been reading and I guess GM made the switch to LS2 style rods in late 04. I would think that'd be useful info to include...

Okay you calculator guys, I'm curious as to what mine is? I haven't dyno'd it except when it was first tuned on a 5lbs of boost. Car weighs 3680lbs with me in it. Has gone 6.04@115mph. Has a best mph of 118.92 mph. In the 1/8th mile. I figured I was probably around 700 to the wheels.

Nice! I was looking at the thread on my phone previously and could not really see everything. Awesome results. Once that boost starts coming in, it is a rocket ship! What kind of a dyno was that done on?
