Calling all Boost brothers....what's next?

[kwhauck]

It will be a tight fit but you could like he mentioned run a Air-To-Water intercooler. you can get them very comact. might take a few slight modifications but will be worth it... And you can up your boost as well. Ive seen a Alero as well local to me with a A-2-W cooler.

Alot of different shapes and sizes:

same alero.......

TVS swap?

Forgot to mention I'm already using NGK TR6 spark plugs and I custom tune with PowrTuner software.

Swapping the m62 for the m90 is not an option on a Grand Am....it's only been done by a few by swapping out the 3400 for the 3800.

I think I'm going to upgrade the valvetrain like many have suggested already since I'll already be in there when I get do the P/P mani's.

Probably won't do the 3500 top end swap and I wanted to stay away from the alcohol injection for now....no room in the trunk for a tank.

Injectors are not maxing out yet so they're fine and everyone i know that is running this S/C set up is using the afpr as it raises pressure with boost. At idle it's set at the stock pressure.

Engine bay is really tight so trying to add piping to an intercooler is almost impossible.

Thanks for the suggestions so far......looks like I'll have about $800-1000 to spend including the cost of the P/P.

That engine bay is clean as shit!!! i have a soft spot in my heart for boosted GA's

* P&P the blower (know the L67 guys get good gains from it)

Sell headers and S/C and go turbo? lol it will make more power if thats honestly what your looking for? hell you might make money after selling everything and still make more power.... Turbo's are much more efficent and don't strain the trans as much.

hehe, after much reading/learning I preffer a turbo to a super anyday. Only thing I like about supers is the sweet whine they have at low rpm mild acceleration.

How about upgrading the internals? forged/hyper pistons, rods, crank....Moly rings? I hear there are gapless rings now that add a good deal of power over regular gap rings.

I was going to install forged pistons but changed my mind for hypers. Some think it's crazy but....hypers ARE better for a daily street performer and will work better then forged if the tune is right. Hypers have tighter clearances and fantastic heat resistance. Only thing forgers have over hypers is the ability to take abuse from a bad tune. Keep the tune good and hypers will go a LONG way. At least, I plan to hit 15psi on the hypers and no more. 180 lbs/ft x 2 = 360 lbs, not bad for v6. I know I'll hit more from other modsand the torque will more higher....I'll wait to get specific for a dyno read out.

Haha, so it was.

^^ , 3500 top end swap. And/or a cam.

Route the charge pipes to an IC, then back to the TB.

This + upgrade to 38lb injectors I wouldnt be surprised if you werent already pushing max PWM on those dinky 28's.

[robertisaar]

it's easy enough to check duty cycle, if it's not hitting ~80% or higher, larger is just going to cause unnecessary problems.

[Driver_10]

Ive seen 3800 v6s idling happily on 65lb'ers before. Ill be using a set of 85lbs myself since I want to be able to use E85.
However, if hes doing good with an adjustable FPR, then its all cool.

That would put it upstream of the blower

Runing 42# injectors, idles just fine. onces the ECU is corrected for the larger injectors it does a good job doing what it needs to do to idle.

[AleroB888]

Larger injectors, or different types of injectors may not idle correctly or be usable in cases where the throttle body is far from the intake manifold.

I've gotta say, I have some 96 lb/hr (1000cc/min) injectors in my Honda and they idle better than the 650cc injectors they replaced (stock was 360 cc/min or around 33 lb/hr). If you can tune for it, some very large modern injectors can be made to idle quite well. Piggybacks seem to max out at 2x the stock injector size if they rely on fooling the MAF/MAP readings. If you have a piggyback with direct control, a standalone, or injector tuning capability via HPTuners, EFI Live, or DHP, then large injectors shouldn't be too much of a problem. In fact, those injectors idle better than my 42.5 lb/hr injectors in my Monte do.
