Default 98 t/a Results

So i finally had time to get to a dyno after a year and a half. Dropped by keiths pit stop in Gettysburg pa. Did 3 pulls first was a test run he said made 385.08hp 385.48tq at 5500 rpm, second run was a full run made 394.01hp 387.23tq peal at 6000 dropped off at 6300 and third and best run 399.63hp and 392.74tq. He said my tune coulda been cleaned up a little and I could broke well into the 400 mark but I'm happy with what I got. This cam is coming out in a few weeks anyway to go bigger. What you all think

Mods: stock 98 ls1 block, m6, stage 1 monster clutch, Howard's cam version of gm asa cam 226/236 .525/.525 110 lsa, home ported 799 heads, trinion upgraded rockers, 42lb injectors, professional products 96mm intake, Nick Williams 92mm throttle body, volant cai, obx headers custom true duals with x pipe rear exit no cats, 3.73 rear, and heavy *** American racing rebel series wheels and im sure i missed something.

Gotcha. Numbers seem a bit low so that's why I asked if you ran it at the track. I never go by dyno numbers

Most HCI LS1's like this would typically be in the 420-440 hp range; but dynos vary so it's not a good measuring stick

Yep I hear you. I'd definitely consider looking into a different tune as well
