Pulley size combo , top and bottom? Any idea about IAT2 ?
MMR Stage 3 cams, 9.5 C/R. Car had just been put back together and just needed to check fueling. Just haven't been back to the dyno. I think it would be close to 870 at 6800 rpmVery nice! :beer:
What cams? compression?
Why stopping under 6k w/ cams?

Anybody else got some high HP numbers from a Gen 2? I'd like to see a dyno sheet from the BPS car, but I don't think they've posted one. I bought my car with a 4.5L Whipple on it, but I'm seriously considering buying a VMP to gain some more mid range torque on the street since that's where I drive my car 99% of the time. My car makes 897 RWHP and 752RWTQ on pump gas at 19 PSI, 1200+ on race gas and high boost. I'm guessing I could gain at least 75-100 RWTQ with the VMP and maybe lose 25-50 RWHP at the top of the rev range on pump gas. Maybe crack 1000 RWHP spinning the TVS as hard as possible with lots of timing on E85.
no dyno sheet to show and to be honest , i haven`t been on the dyno in over a year, we datalog every test run and this is all i need
we can easily convert maf counts into hp to keep track of the progress
you will gain low and mid range but also loose on top as you guessed
should you do it? it's up to you
how much hp we make you can ask, my answer to you is enough to go 8.7's with a soft tune while blowing the tires in 3rd gear and having traction issues most of the run

Thanks for the reply! Love your car and I follow you guys on FB. I assume you guys are running a 20%(or larger) lower. What mods need to be done to use something larger than a 15%?
BPS. I have some of your parts on my car. U make nice stuff! I am currently running a gen2 tvs 10 pct 2.5 and making 740saewhp through a 4l80e on the stock longblock. I just bought a new built long block at 10 to 1 compression and cams. I am going with an ati 15pct balancer. Do you have any problems overspeeding the tvs? Not sure what rpm you run at but I plan to spin mine near 7000.
