View Full Version : how does this look

Just got my car back from builder, Cam is an EPS 230/234 600/612 on a 113lsa +2 speced by Patrick G. patriot predator heads 64cc then milled .010 to 62ish cc with GM mls gaskets. ls6 intake with ported thottle body, 42lb injectors all thru a M6 and 12bolt.

What do you guys think about this dyno graph, engine would only take 23* of timing without detonation on a 91 octane tune, thats all we can get around here. was hoping for a little more last engine had more compression and took 27* of timing.

No replies, was hoping to get some input

That looks pretty good. I would expect a little more tq with the heads/compression but maybe I'm wrong.

The lower timing might be contributing there. Overall it looks like a stout combo that peaks at a reasonable RPM under 6500.

Some more tweaks and it can only get better.

anyone else with opinion or thoughts please chime in

not bad.. i'd be happy with that. I'm sure with a little more timing will help you out but if thats all it will take then thats all you get. what kind of exhaust are you running still True duals? I ask because I just dyno'd my car and it was 435 rwhp and 400 rwtq.and thinking of changing my exhaust to true duals. see sig for mods.

true duals over the rear axel, thinking of coming up your way and have brian at hitech motorsports do his magic on my tune he has always done this car but had it tuned down here where engine was built. dont think he is quite as experienced as brian is.

You have to be kidding me 345 views an two responses thought tech was there to help out I guess not. I welcome any input !!

Looks fine for the mods. Probly more power ditching the duals over the axle.

What are you looking for?

I wouldnt go to hitech motorsports. Ive heard alot of horror stories from there. Theres other tuners in Mn that can do better.

was hoping for a little more than 400 on torque thinking the lack of being able to take more timing is the issue. last build had a tad bit more compression and still took 26* with out any detonation. thanks for the imput any ideas will sure help.

Are you coming up to car craft this weekend? I dyno'd my car at high tech but had boos performance tune it for me. he did a great job and is right in town here too, I to have heard a lot of bad things about high tech although i've never had them do anything for me.. Good luck.
