if header : get a 4-2-1 and not a 4-1!!!

get cold air intake or short ram intake

probably i would go for weaponR 421 header which i believe comes with the s pipe. and weapon r intake. hks muffler with custom 2.25 inch exhaust. not 2.5 because u will loose backpressure

yes, firm shifts . trans likes to shift right before redline when in wot. or manual shifting ... it was fun driveing my auto, quicker rev ... not to sure . well i did 9.58 on 1/8 drag. on auto trans ....
from that thread, quicker revs firmer shifts, shifts perfectly b4 redline

Eh, I'd rather not have to deal with the added noise, drone and in this case rasp that would come with ____ing around with my exhaust set up. I ran SLP LMII's on my old car and that drone got real annoying after a little while on the highway. It's just a daily driver, you know what I mean? I don't really care for intakes anyway, short rams are a joke that just suck up hot air from the engine bay.


Rosedale - Yeah, I'm from Whitestone.

It's a white one, nothing to identify it from other ones except the shorty antenna though. Until Saturday though it'll be the white one with the huge dent in the front bumper from when someone backed into it haha. I spend most of my time out on Long Island these days, since most of my friends live out in Nassau but I'm definitely in Whitestone and Bayside a lot too.

not sure about auto trannys,but RAdo does have a 5 speed with differant gears in it,one person up here has it and although I am not sure what the differance is he was looking forward to putting it in soon........he autocrosses a lot and is friends with Rado so that is how he got it.........Descendant may be selling them by now too.

Whats this about back pressure? I've done some research showing back pressure isn't a big issue enless you get to the extremes of pipe diameters.

Rosedale - You ever go out to the meets at Roosevelt Field mall or out in Deer Park?

Spoofa - The whole back pressure thing gets talked about so much and people make it out to be a much bigger deal than it really is.

I'm not breaking traction, never said I was. My driving is fine, I was just asking a question about doing something more efficiently. These cars are too slow for you to really have much fun driving them so it's not like I'm driving the car hard at all.
If your not breaking traction then their is no point in doing anything because you are already putting power to the ground efficiently enough.

Folowing your same logic I have another tip for you...Upgrade your fuel pump to a more efficient one that flows enough for a 600hp setup. Your horsepower and times wont change one bit but at least your fuel will be flowing with maximum efficiency.

Its an easy issue to settle with one car..Do one dyno with exhaust attached and another with open header (no backpressure) and see which puts down a better power band. Not the biggest number but best power band.

if you want to put more power to the ground - your very best bet is to get 225 tires instead of 215's (they fit on the stock rims) and also to get the ingalls engine dampener. That will allow the engine to sway less under hard shifting and keep more power to the wheels. I think they are cheap now (under $200) - Normally people use them for turbo/sc cars but it will surely be fine if you used it with your NA car. There are settings on it - i used to run the stock setting with my s/c - you can make it one less if you want (or change it to be a lot more then default if you wish).

That is the cheapest way for an automatic to get more power down.

can you explain this ingalls engine dampener more? does it actually free up more hp and tq or does it allow for faster harder gear shifting?

nah it has nothing to do with power. its more like a mount that holds ur engine in place so theres less engine shake and wheel hop.

it makes the shifting a lot smoother. basically what it does is strap the engine down to the actual body causing the engine not to move around all crazy.. though a damper is a waste of money and you should just buy motor mounts... half the money and does the job wayy better then the damper would.

o really so motor mounts are better than? is this a tangible improvement in performance in any way or is it strictly for a smoother ride?

energy motor mounts are by far the best thing out there apart from spending hundreds for an LSD (5spd only) motor mounts keep ur engine in place no shaking nothing and it improves wheel hop a great amount. no more peeling out and ur front wheels jumping around. and for 60 bucks shipped its great, the only downfall is that at idle ur car shakes instead of the engine, which is ofcourse going to happen cause ur adding polyurethane mounts so watever the engine shakes ur car is gonna feel it, but totally worth it
