ok, but i do drag...

do YOU guys have or had any problems with this stuff? wat are you running?

 

Umm...

 

I believe he's talking about drag racing from a roll guys...

 

Thats not drag racing, but whatever. I call that roll racing or bakery racing.

 

sorry, but jsshhh, if you're not completely technical on this thing, its like the whole point of the forum just dies and becomes a call out...

yes, i meant from a role not a dig. at the very least, i will start at 20mph for a pull.

look, has anyone had problems with their oem differential or tranny parts, etc. form being FI over 400whp? If not, forget I wrote this forum. thanks...

 

It really is a hit or miss. Most people will tell you yes you will have problems most likely with your dif at that power. Given that from a roll is def less stress on the dif then from a dig. Personally i have been running over 600whp with some drag racing from a dig at the track a few times but mostly highway pulls not a problem trans or dif.

 

really? and this is your oem tranny/differential? no replacing parts yet?
If so, that makes me feel better

 

There are a couple more stories like that and then there are the people who break stuff on stock power.

To minimize your downtime, keep cash or parts on hand.

If you beat on it enough, stuff (axles, diff or tranny) is going to break.

 

Never broke an axle. But I've been through one trans and two diffs at 300/350whp range SC. Spirited daily driven with very very few hard starts/ dig racing.

 

Frankly this isn't exactly consoling for those looking to go FI. Apparently those "very very few" hard starts are "very very hard" on your differential. Clearly, caution should be exercised.

Along the same lines, people were breaking AP1 differentials at stock power with high rpm clutch drops. This was the reason why honda added a clutch delay valve on the AP2 to help reduce drivetrain shock.
