What's up guys? Been away for awhile. Did some supporting mods and swapped in a new set of cams from MHS and a built trans from promotion, added in a 4500psi NANO. I dropped the car off with Greg at Speedy Dyno in Owensboro, KY Tuesday for a retune and to add a bigger shot of nitrous. I just got off the phone with him and he said he got her to lay down 317/330 NA and 586/631 on a 100 shot. This is all going through a Super Flo Dyno. Last tune I put down 354/330 on a Dyno jet, but the nitrous was no where near as powerful. Greg said he couldn't believe the numbers at first, so he ran it again and it spit them out again. AF are 12.0 on the hit and then drop down to 11.5. He is now tuning for a bigger shot and I will keep you guys updated as I get more info. I have jets to make roughly a 175 shot, but he may exceed the TQ limits of my trans before then.

Awesome numbers! I saw the car yesterday when the first bottle was empty. I didnt hang around for the new bottle though. Greg tuned another nitrous 2 valve this week as well. He has a great N2O tune for sure

I talked to Greg again. I must have misunderstood him earlier. Those numbers were from a 150 shot. He is doing a 175 for the top end, a 100 shot tune and a motor tune. I am very happy with the numbers so far.

Thanks. I am looking forward to it.
Personally I wouldn't spray more than 150 with a wet kit and long runner intake because it could cause fuel to fall out of suspension, puddle in the intake, and go boom. 150 seems to have always been the accepted maximum with anything other than a Vic. Jr. Or Reichard intake or a single nozzle or plate kit.

Either way it's producing really nice results.

I have a shark nozzle, and TFS intake. 175 will be the limit cause I am approaching the limit on the trans now. I understand about the fuel possibly puddling, but running the rpms that I am turning, I hope it will be ok.

Last time I weighed it with me in it, it was right around 3550lbs.
