so last sat a group of us here in town got together to do a dyno runs on our Gs.

My mosd are V2 vortech kit with stock headers, cats and exhaust..

i was expecting a lil more but i guess that not bad cosiderning its prob on low boost..

first run was done in 3rd gear and 2nd run was done in 4th gear. temp was around 90 degrees in the shop.

are these normal numbers for an 03coupe with my mods?

 

That is low, but you don't have any supporting mods. A less restricting exhaust and a retune would help a lot.

 

yeah thats the plan.. Art pipes/CBE(hopefully i can afford MD TDX2) and Uprev osiris

 

intereted in a Geddy Evo Exhaust? i'll be posting one for sale soon.

 

Does look low. What pulley are you running? How much boost are you making? Any fuel upgrades?

 

im saving up for a MD TDX2 and art pipes... but thanx for the offer though.

heres the thing. i purchased the vehicle already with the Vortech Kit on it and the previous owner was not a car guy, he just got the car as part payment for a business deal. Ive always been into modding my own cars i come from owning a 3rd gen altima with the VQ35 that i had pretty much every bolt on and suspension mod availble for and it was all done by me.
however, when i ran into this G it was a great deal and i could tell it had been well kept, paint and interior are in excellent shape.
anywho, im not sure what pulley its runing but i assume its the one that comes with the kit.
the dyno shows the car is runing a lil lean so im planing on taking the car to Rob from Zcar Garage in the new few weeks so he can check it out and let me know what was done to the car and wat needs to be done as far a fuel upgrades and other supporting mods.

 

Install ur supporting mods then get ur tune.

 

keep in mind different dynos put out different types of numbers, Mustang dyno jets give out less HP rating than others, you should probably be closer to 350hp

 

I hope you get your supporting mods very soon. I never seen a G that is running FI below 300. When you get all those supporting mods on, i say you go to Church automotive and get a tune. They do awesome work over there. Soon i will be getting a tune but i still wish i was FI.

 

Zcar Garage is a good shop. I'm sure all you need is a couple other supporting mods with a retune and you'll be good to go.

 

Yeah well it put down 308whp but im planing a visit to Z car garage in the next few weeks to make sure its all checked out.
Already saving up for the md Tdx2 and art pipes

 

You planning on getting these mods soon?

 

You might be on a complete (non-tuner) kit with a stock 3.33 pulley. Since you already purchased the injectors and fuel pump all you need is the Uprev software and a tune from ZCG. You are in good hands with Rob. He does amazing work! The Art pipes and the MD exhaust will be the icing on the cake.

I would drop to a 3.12 pulley though. I think I have one, let me know if you need it. Goodluck

 

Like others said, if you make sure that you have the 3.12 pulley, injectors and fuel pump, and some sort of less rescricting exhaust (anything aftermarket pretty much) and either tps/HFCs/arts, your tuner should get you anywhere between 360-420, depending on how conservative you want it.

Also make sure that they check for boost leaks, you might consider upgrading to silicone couplers and t bolt clamps to avoid that issue in the future

 

numbers look very low and looks very lean if thats the tru a/f ratio..


are u on stock 3.33 pulley? i put down 350whp on the stock pulley and 420whp on the 3.12 after being tuned with a few other exhaust mods and such..nothing major

ur a/f should be mid to high 11's max..i wouldnt rip on it with it being that lean
