i know that you people have done some mods to your car but how much horsepower you have(or think you have) with your setup? without turbos of course.

Word of warning, benchdynoing is kinda frowned upon here. If folks have actual dyno sheets, we'd love to see em.

ya get rid of that "think you have" part

yeah, get rid of think you have, because I like to think I have 600hp without turbo, but we all know I don't... I just like to think it.

I'm glad you asked this, I was about to post what #'s people are getting from their g-techs...

I got 109

140hp.

:laugh: :laugh: :laugh: i think your too optimistic

i thought the 420a power plant was rated 140 at the fly wheel?

It is rated at 140 crank hp. whp is what you get when you dyno your car it tells you the hp you are putting to the ground. You gotta factor in for drivetrain loss etc...

208whp/182tq
Just to throw mine in even tho I put a turbo on it im still kinda a nonturbo 420a powa!!

Its not for brag talk, I just want to have some reference to determine an aproximate hp value for my setup. If i dont have any reference, then how do i know what hp i may have with my setup? (forget about dyno's they'r not popular here)

get desk top dyno. but im warnign you, you need to knwo all messurements and clearences of your motor to get ti to work right.

i got 115 from my g-tech today

How much power do I think I have? Well... I don't think it's enough.

hey i dunno aboout you guys but a dyno here charges $75 for 3 runs... do you have to take all 3 runs at once, or can you take one at one time, and 2 more at another??(i wanna go dyno it now without nitrous, then after i get my header, downpipe( ) , high flow cat, and s-afc II on ill tune it and take it back in a couple of weeks, do one run without nitrous and one run with... see how my gains are and see my tuning ability ) i think a modest goal would be 200whp.

200whp with nitrous? yeah right. You'll need a lot more then exhaust mods and nitrous to make 200 horsepower at the wheels. Even running a 100-shot you'll barely push 180.

But yeah, my car makes 122whp but I'm down 20lb-ft of torque from stock. an exhaust as big as mine = not worth it. I don't get a surge of power (which usually happens at around 3500rpm) until right before I have to shift. My car is probably slower then a stock 2gnt.

Bro how are you going to tell me he will not dyno at 200 to the wheels with a 75 wet shot? Did you even bother looking at his profile? My $ is on that you did not. By the time he dyno's chris said he has/would have cai, header, hi-flow cat, cat back, underdrive pulley, afc-II, and a 75 wet kit. Yes consider our stock whp is around 115ish i think 200 w/ nitrous would not be as hard as you are making it seem.

EDIT: YOU HAVE A 3.0" CAT-BACK ON A N/T CAR and you wonder why you are getting such a loss switch over to 2.5"

I didn't put the catback on the car, the previous owner did. And our cars are more like 105whp stock, and exhaust and intake and high flo cat, whatever will bring him to around 130, and then a 75 wet shot adds 75 horse at the flywheel so take drivetrain loss into account all of the sudden he's only making 170, 175 at the wheels.... fact of the matter is, intake & exhaust mods don't do much for such small motors. Boost of one kind or another is the only way to make any significant gains with a 2 liter.

your both wrong. if your car has about 105whp stock and you do all that work, cai,exhaust,headers,pulleys, and all but no cams or anythign your lookign at abotu 125whp maybe 130 before nitrous. you dotn gain that much n/a without cams and such. itll breath a little better and youll get abotu 25 hp tops form all those mods maybe 30. so say you get 30 you got 135whp now.

the size of the shot you run is not the hp you gain. ive seen dyno clps a guy had a 75 shot on a very worked motor and turned 585hp before nitrous. when he hit the 75 shot he got to 611hp. that is way less then the size of the shot.

you will never get a nitrous system to give you the hp form what size it is. if he runs a 75 shot on a n/a motor with 130whp he might get 150-160 whp with the nitrous.\

sorry to ruin your fun. i just speak the truth

im gonna brag about about my hella 15hp. im slow 0-60 tommorrow.

Someone dyno without spray, then with. Lets see what a 50 or 75 shot really does. NX claims to be close to the size of the shot.

Woo Hoo. Got all my electrical issues worked out. my cars dyno was pitiful--DAMN YOU ATX DAMN YOU!!!!! I dynoed at 95hp/95tq N/A and 145hp/151tq on a 50shot. It was also 98* outside and at 51xxft above sea level. It was a rush using it for the first time, made me want more but I think I'm going to try and exercise some self control and keep it at 50.

wah lah.

105whp stock? so your saying a 25% drivetrain loss? ok then with the nitrous you say you go from 130whp to 170whp after drive train loss with a 75 shot? so now your saying a 46% drivetrain loss. manuals usually have 120hp to the wheels stock, or about 15% drivetrain loss. you say our cars make 105whp stock and you have 122whp with intake and 3" exauste? sooo almost 20hp from intake and exaust... come on...

was that 585whp dyno with a turbo charged engine? cuz if it was then a 50 shot would have given him well more then 50hp, the incredible cooling capabilities of the nitrous transforming from a liquid to a gas will completely get rid of any thremal expansion. dsmjim says a 50 shot will give 100hp, and then its just 50 + the shot from there. i think dsmjim knows his stuff.

you guys are being rediculous.

9D9 MITSU RS, i think im gonna go take a few dyno runs very soon before i put my header, downpipe( ) highflow cat, afc, and 3" muffler on(mine now only has a 2.25 inlet which will be constricting me, i think im gonna go with a apex N1 turbo muffler). ill do 1 run without nitrous and 2 with. then ill go back after all thats installed and i tune the afc and see my gains. but i thought my 200whp goal was very modest, and im very confident i will achieve it.

yes it was on here. it was a black 2g tsi from this team mabr guy. it was posted a hwile back. and youll never get 100hp from a 50 shot. thats obsurd

well dsmjim does have that wiseman status... and his theory makes sense, so i believe him

ho wcan you possibly get 100hp from 50 hp jets.

thats like gettign water from a stone. it can not happen.ive been around motors and gear heads all my life. i knwo it cant

heres how i see it happening. when the air is compressed by a turbo charger, the natural reaction of air being compressed is it heats up. when it heats up it expands. now you can be running X amount of boost, but that is the pressure, not the air density. so the air density isnt as high as it could be because its hot, and its expansion causes the pressure. when the cold nitrous is injected into the hot expanded air the air is cooled and contracts. now your running the boost with higher then normal air density, plus the high oxygen density of nitrous after it breaks apart under high heat. those are some of the reasons why you get so much power. i think boost creep may also be apart of it. ill try and get dsmjim to get in here.
