Thread: Guesstimate on power, transmission safety?

So I'm just curious, with the mods listed in my sig, what kind of ballpark should I be looking at for power? I will be getting it dyno tuned in a few weeks or so, but my curiosity is getting the better of me, I was guessing somewhere near 300 at the wheels?

Do yall think higher, lower?

And secondly, do you think it's generally safe level for the trans? Or should I start saving up for input shafts?

You could look up similar mods that have been posted with dyno tunes. Off the cuff I am seeing a 3.2 IC'd with 1.9's and headers for hard mods then the tune to loosen stuff up. At the crank, you could be seeing around 300 hp possibly. Take off about 25% for transmission/axles and that's about what would be to the wheels.

Transmission really depends on your driving style. There are people who can have a trans be reliable on that power and there's some that can't keep a trans together on stock power. The key to remember is this is not a good transmission when modding or even driving a stock power level like you stole it. Me.. I had S1X cam, Gen V, N*, headers and could stretch a 7/8 chain in under 5K miles. Most of the time much less. As I added power the transmission became more and more of an issue.

I'm guesstimating whp is around 240-250 and torque being slightly higher since these motors with the blower love making torque down low. before my stock trans (was tuned though) chain stretched and snapped (was only cruising when it happened and not while racing) I prolly had 150-200 track passes on street tires (no drags or radials) with no long burnouts at all. prolly only spun long enough to clean the tires whenever I go to the track and skipped the waterbox. ran plenty 2.0-2.10 sixties.

edit this was with varying pullies from 3.2" to 3.4" running 25-28* of timing with alky injection

I tell you what, 2nd gear is kinda scary now.

kinda nice when 2 nd gear has a reason for life. add boost, second gear now works lol

Depends how your shifts are set. I've seen 14 second cars break input shafts because they had the shifts too hard.

For 300 hp to the wheels I am running E85, higher compression from top swap, VS cam, 3.0 pulley, and all the complimentary add-ons. My trans didn't last even when I was N/A. LOL. I am guessing 260 to the wheels.

Well the funniest part, is that I forgot that I was leaving traction control on, 1st gear is about worthless atm
