We did some more dyno tuning today with the Mufflex 3" y-pipe in place (previously had 3" pipe coming off the header, into dynomax bullet muffers, and dumping before the rearend). We were able to get 442rwhp/408rwtq out of it on three few pulls (very consistant) , along with 410rwtq on another. Geoff did a little tuning to help clear up that flat spot in the graph. I'll post the graph later tonight of the new pulls done today. Overall, I couldn't be happier with the numbers! It has far exceeded my expectations. The new cam (V.2) should be installed Thursday evening. Look for some dyno numbers LATE Thrusday night or Friday morning.

Have you driven this cam on street? What rpm does this cam surge at? Will there be any testing on a 98-00 car with stock heads? What is the predicted price on the cam kit?
thanks,

So before you jump down my throat with a shitty reply..do a little bit of research!

Many say the 98-00 heads are different (different casting number), and they don't flow as well as the "241" heads on the 01+ models, thats the difference I want to see. Yes, he said the driveability was good, etc. To many "driveability" means as long as it stalls every other stop light instead of everyone its driveable. As far as cam surge...I guess you don't know what that is either when driving a big cammed car. Can this car cruise at 1,400rpm in any gear except 6th and not buck slightly like certain big cam cars? (My friends ASA 226/236 .525/.525 110lsa does this unless your good with the throttle).

as for the drivability, when i talked to him, he said it was much better than expected with 3.42's and would be easy to drive with 4.10's or lower, never heard any mention of stalling. just trying to relay info, dont jump down my throat either.

GrannySShifting, we did mess with the tuning in that area and saw some very nice gains. The y-pipe helped some, but alot of it was with the tuning. The testing was done through an open y-pipe.
94-98 Trans Am, yes, I have put about 30 miles on this setup so far. The cam does have some surge below 1600, but my TR230 did as well. Gears will help with the driveability A TON!! Once we finalize on the cam selection, Geoff is going to tune the drivability, and, by that time, I'll have the 12-bolt/4:xx gears installed. Then, I can give you a better idea of how this cam drives.
SSInnovations, I feelt his cam would work extremely well with ported heads. PtV clearance will be your biggest problems with using them with milled heads. Flycutting will pretty much be mandatory. This is not hard to do with the heads on the car with the proper tools. It just an added step when going with cams this big.
taqwache, no problem!

Sounds liek ti drives just like our manly cam. Surge a bit 1500-1700, but honeslty I have nowhere near tthe amount of knowledge in the driveability area as some guys like Thunder and Nogo do. Is it open loop tune all the time? Nogo said I should go this route, although Im working with closed right now.
Getting it to idle wasn't bad, but on start ups it idle down around 500 for a couple seconds - then would hold 1000 steady. never did stall. Fooling with an odd table ive never seen anyone talk about, I was able to get it to start with that slight low idle only lasting maybe .5-1 second.
Id be really interested to see how much that flat spot cleaned up, and what it took. How bout this, if I can geuss the cam specs with a degree or two, we trade edit files
