I have to keep those dyno numbers hush-hush since slowprocess has me on his call out list I dont want to get him all shook up before I get to run him again

Maybe I'll have a few tricks up my sleeve by the next meet. Besides....you ONLY have an exhaust and intake, so how high could the numbers be, eh?

I dunno, I am gueesin.... 375rwhp

Motor pull(this is with a nitrous tune, and alot of timing pulled out of top end) 391hp & 486 ft lbs.
First NO2 pull:max HP & TRQ 480/620 1/4 mile simulation 1.607 11.698 @115.037
2 NO2 pull:Max HP&TRQ 482/622 !/4 mile simulation 1.67 11.678 @115.370
I am not counting the real 1st NO2 when I didnt purge the lines, and when the truck took the nitrous it broke traction and started burning tires on the dyno and ran a 12.07 1/4.

Nice numbers, I can't wait to see that truck at the meet! You wouldn't know of anyone that's ever went and been dynoed at Street & Performance Electronics in North Little Rock would you? I was planning on heading over there this summer but I haven't ever heard anything about them and what all they can do..

Good numbers. What size shot of nitrous? And curious, were the runs made with the converter locked or unlocked?

I never heard anyone getting dynoed there, but I have heard of them doing some shitty computer tunning. They charge about $150 for dynoing. If you got to Fast Forward in Eudora/Lakevillage, Randy will do 3 pulls for $75 or I think 1 hour for $75.
It is a 75 wet shot, and I dont know about the converter. I am guessing it locks at full throttle, I have not modified anything with the transsmission at all, so it is does what ever it it did from factory. I a going to have a 2400 stall going in a few weeks I think though.

I was wrong about the 60' time on the 2nd NO2 pass. It was a 1.587.
I am pretty satisfied with the numbers but, JLP is going to have to adjust my A/F in my tune. It is burning BAD rich, so when I get it leaned out some, I should have some better number, and I think I am gonna bump the N02 up to a 100 just so I can break the 500HP mark.

Very nice numbers on that lightning. What did the torque curve look like? I'd love to see that.
