Hey guys

Just looking for some info on the difference between the 71 and 65 exhaust wheels. What im after more less is if there's a big gain to be had with the 71? I currently have a 62/65/12 and just wondering if this thing is gonna do it for me as i got TST PM comp, mach 4's, and a smarty. The HTT 62/65/12 is still brand new and im just wondering if i should send these thing to HTT for some upgrades before i get all this stuff on.........if they can easily upgrade it.....

Thanks

Jeff

I went from a 65 to a 71 on a 14 housing, not sure you can do it on a 12. I saw cooler egts with the switch.

If you have M4's, you will get hot with the 65 wheel. I've run a 62/65/12, 62/65/14, 64/65/12, 64/65/14 & the 62/71/14 is working better than any of them. I would definately get the upgrade. Actually, I would see if they can do a 62/74/14.

Or run the 62/71/13ss.

Or run a stock 3rd gen turbo and lose 50 HP but gain 1000 bucks.

The 71mm turbine will make noticable more power and cooler WOT Egt's.

is there anymore noticeable lag going from a 65 to 71?

Only slightly.

There is a little more lag at first, but from 10psi-50psi in half the time.
