Default LE2 Dyno results.

Hey Guy's, got the car dyno tuned today, It put down 391RWHP and 370ft/lbs of torque, was hoping to break the 400 mark but I got pretty close. It is the smaller emission le cam. My mods consist of:

1994 Z28 m6 the car has the
Le2 heads, LE ported intake,22x/23x 112lsa cam,
1.6rr's, 58mm throttlebody, lucas 38# injectors, lt4 knock module, cai,
pace setter long tubes, Ory, magnaflow cat back. 3inch qtp cut-out, elec-wp,
160* thermostat.


I'll try and post the dyno graph up as soon as I can I dont have a scanner so I guess ill take a pic of it and load it up.

Good #'s for an emissions legal setup!

I agree a few little boltons/tweaks and she'll punch that 400 mark.

Depends where you live. I know for sure we can have long tubes here. We are supposed to have cats too, but they don't even bother to check. They figure if you don't have them that you will fail on the sniffer - which isn't always true.

By the way, nice numbers.

Theres nothing non-emissions legal about long tubes as long as you have cats. I have a catted y pipe I run when its emissions time.

Yeah def with an electric wp you should either hit 400 or be very close. Not bad at all for a relitively small cam. Nice job.

It's illegal to move the location of the cats which makes longtubes are illegal in 50 states.
