Ok, I am an LS1 owner, but I recently went down to Abacus racing in VA Beach with my buddy Eric to do some dyno runs. He was doing some wideband tuning and programming using CAT tuner. His mods are: ported heads and intake that flow 245/180, hot cam, 1.6 rockers, 52 mm throttle body, jet hot long tubes and a cold air kit, dual cut outs, and an electric water pump. He pulled 354.2 RWHP. He runs 12.7 at around 110MPH on Eagle F1s.

Cool vids.

 

Nice!

 

Yeah Baby!!!!

 

322 a4 w/ a lid n a catback way more impressed w/ the LS1 numbers considering the LT1 has all the bolt ons plus a cam n ported heads and only putting out 30 more hp

 

Yeah Eric said "Damn, only beat you by 30HP and your motor is stock!"

Was the Lt1 a 6spd or auto?

 

My heads flowed close to your buddies and I had all the same modifacations as he does, including the hotcam. I pulled 372 rwhp and ran 12.3's @115. Let him know that he could get a little more out of it with some tweaking. Still not bad numbers though.

 

6 speed manual. That was his first attempt with the wideband, and he didn't have a bung for the sensor, so they were sniffing at the cut out. He didn't get any spark retard, so he wanted to try some more advance, like 6 degrees, but he ran outta $$$ and dyno time I'll let him know your results though!

I would have played some more with the afr's and timimg but i ran out of time. It was a very hot and humid day so i probably would have closer to 360-370 in cooler weather. I got 12.7 @ 113 w/ a 2.2 sixty at cecil county 2 weeks ago.

 

Last time I went to Abacus, I had a crappy G2 CAI, a cat back, and (didn't know at the time) some very crappy plugs. Only got 240 rwhp.

I've done a few things since then I need to go back soon.. Chuck still there?

Nice #'s btw
