question for the 3s guys

[dustinw]

looking into getting a stealth TT this weekend.

the guy is claiming 450 awhp.
i know theres a shit ton of variables but with these mods, do you guys believe 450 awhp is possible with this setup? im thinking more like 375-400 but thats just me.

1992 Dodge Stealth R/T Twin turbo AWD, Dynamic Racing stage II heads, 99 lifters, 6-speed Getrag from 99 vr4, Southbend Stage 4 DXD-B Clutch, TEC 15g's, Greddy blow off valve, Dejon Powerhouse Blow-Thru Intake Pipes, DSM sidemounts, Denso fuel pump, 550cc fuel injectors, Apexi SAFC, HKS VPC, Apexi AVCR, msd ignition dis-4, MSD 8.5mm wires, NGK coppers 1 stage colder, y-pipe, borla catback, ATR downpipe, highflow cat, Lowered, Nitto tires.

car will also be coming from 7300ish elevation down to 2200 or so

[AwdGSX13]

the elevation change will have an effect. coming down should make it run better due to more oxygen i believe.

[turbotalon1g]

Is that pump or race gas? what is he using for engine management?

Its doable on pump i wouldn't doubt it too much.

[DSM_421]

Those injectors seem kind of small.

I guess you will have to test drive it, should give you a good idea on how much power it is making.

[dustinw]

not sure on engine management, and its on pump gas.

[vr-4lif3]

"550cc fuel injectors, Apexi SAFC" I doubt it's at 450 with no timing control.

[dustinw]

heres what im trading him for it :

The engine management would be the SAFC.

We have 6 injectors. That's like 825's in a DSM.

Has a HKS VPC too. Old school, but works good.

As for making 450, it's debatable but not out of the question. The DR heads are a big help. Also if it was dyno'd at altitude with corrections, it will bump the #'s a little.

Yea I guess that makes sense, but you also have 6 cylinders. But I guess with two extra cylinders you don't need big injectors to make that kind of power.

I say keep the camaro.

[dustinw]

the camaro gets about 8mpg, and its only a 3 speed. i need a car that can be a daily driver too.

[123abc]

I would believe at least 350 which is good however you look at it.

I know for that every 1000 feet in elevation you climb, you lose 3% of your engines output capacity, and vice versa for descending in elevation, so you gain 3% every 1000 feet. So you should get a good bump in power going down 5000 feet; roughly 12-15% or so gain. But I don't know how they compensate for a tune. I'm almost positive you will have to get it re-tuned when you bring it back to your elevation. Atmospheric pressure @ 7000 feet is 11 PSI and @ 2000 feet it's around 13.5 PSI or so, and that's a good difference.

Just out of curiosity, are you buying the car somewhere in Wyoming?

Any of the tuners here know what the deal is with getting a re-tune?

[DSM_421]

He will have to get it retuned for sure...

[NOT THE BLUE LAMPSHADE]

thats what i figured because my friend has a 400WHP evo in littleton, co (~4000 ft) and hed have to get a retune if he were to bring it up to laramie (7400 ft)

[dustinw]

ok so if the car is running rich in laramie will it lean out a little bit more if he brings it down here?

[dustinw]

what im saying is i think he got it in wisconsin and it was tuned. then took it to laramie without retuning therefore running rich the whole time. so maybe returning to a normal elevation will bring it back closer to that optimal range.
