A buddy of mine is telling me that in his auto formula that he is in his prime power range when he is in second gear at 70 mph. is this true? mods are as listed...

non-smog legal Pace Setter Long Tube headers
SLP off Road Y pipie, 3 inches
No cats
3 inch Y pipe back exhaust pipe into a Borla Exhaust system
WS6 differential and suspension swap (sway bars, diff, etc)
SLP Air Lid with smooth bellows
Dyno tun of 352 hp (before lid and bellows)
All the DIY mods
4 speed auto that was rebuilt with a shift kit

He is saying that he did this and managed to pull a car on a pullied 2003 cobra. They went up to 140.

He did not pull on a pullied Cobra. His prime power range all depends on the gearing he has.

Yeah,,,,,,,,,,,,,,,,,call big time BS on running away from a pullied Terminator with his mods.

Unfortunately, I have to agree... Seems most 03-04 Cobra's are about 350 rwhp stock. So a pullied one ? say even just a handheld tune (think Hypertech etc) would be about 400's ?
Pullied Cobra = Nice view of the tail lights with those mods. I have more mods and a decent tune. A Catback, pullied Cobra showed me just why they are so respected..altho from what I hear it was most likely not a stock blower or perhaps a ported one.

what im really trying to find out is if manually dropping an auto ls1 into second at 70mph is a good idea or even possible.

Most Termi's I've personally seen dyno around 375-395rwhp. A pullied one, no less than 420+ since most people with pulley kits also have a few bolt ons.

Yep, if an 03/04 only pulled 350 rwhp even bone stock it was hurt. They around the 380 area stock.

70 will drop a 2.73 car into second and into the meat of the powerband. Not sure about 3.23 or above.

Its not a good idea, It a "AUTO" trans for a reason..

yeah it will def hurt it over time, but i dont think itll hurt to much doing it rarely. and at slower speeds.

with my stock A4 3.23s i just drop it into "D" to get it off the overdrive and it pulls great.

what the majority of the ppl posting on here are missing the point, anything can happen on the streets... and its not the matter of who beat who but what the auto powerband is... like someone stated above.. it depends on his gearing, and i think if hes gearing down to secon from 70mph i think its hurting his transmission. it probably wont show it till later down the road though. if i were him id just keep it in OD or just down shift to D. if he really feels the need i would not be going over 35-40mph to downshift to 2..

just my opinion

I meant the auto will downshift itself to second from 70.(2.73's)
