There was a local dyno day and I was curious, so I ran it. Car laid down 169whp and 168tq at the wheels through a 4R70W transmission and detroit locker.

Short ram intake, canned VMP tune(6k rev limit), 2 1/4" dual exhaust with flowmaster delta 40's and magnaflow high flow cats. With 25% parasitic loss comes to right around 225hp&torque at the flywheel. Really makes me wish I had a five speed!

Those numbers sound about right for those mods.

Do you think you might go to a 5spd over the winter?

I've been searching copart.com for a wrecked 04 v6 near idaho. I plan on making the swap this winter, yes. Most of the dyno pulls I see are cars with similar mods, but usually five speed cars. Lot less parasitic loss than my auto, and they seem to dyno the same or a few rwhp less. Dunno, it's weird. Think it's how my exhaust is setup. lose some backpressure and torque, but gain high rpm power. car would be very close to 200whp with a five speed swap.

Nice numbers. Do you have any performance plans?

I wish I wouldve gotten my car dyno'd while NA... going from your results, I would be around 175-180, maybe even 190 range. Lt's, no cats, 2.5" piping and a VMP LT's tune.

man that makes me sad kinda, i should be in the same ballpark as you clif. i do want to do a trans swap one day too though. would it really be that close to 200? 30 hp, now thats bang for your buck!

4.2 swap with a higher stall

Would it be close to 200, no.

ok thats somewhat of a relief, i saw a graph on vmps website that had similar mods as us that had i want to say ~189rwhp/tq

Clif Brohn

Why wouldn't it be? The 4r70w sucks when it comes to parasitic loss, I'd see huge gains if I converted my car to a T5.

Because a stock v6 with exhaust and cai isn't going to make 200rwhp (unless you play with the dyno)
