hi there i dont get a chance to post alot but im diving in, i picked up an 04 gto m6 back in may and i love the car. but i am wondering if the power im making is on par with the mods or low? my first LS car i have helped friends work on theirs but have not owned one until now.

5.7 prc stage 1 ls6 heads pac 660 springs Texas speed torquer v4 BTR rocker arm upgrade OTR- X-air cold air FAST 36lb injectors stock pump
fast 92 intake nick williams 92 TB tsp longtubes catless mids ( dont remember brand) obx exhaust magnaflow x-pipe
stock rotating assembly monster stage stage 2 w/aluminum flywheel

put down 444/395 after a small tune adjustment previous owner had it at 445/407 am i way off course or do these numbers seem low? revving up to 6900 found peak power is at 65-6600 took it to track on a no prep night on ET street R's 245/75 (stock size) got a 1.8 60 and went 12.74 at 110 i know there has got to be some left just me learning the car.

 

What did you guys change in the tune that made it drop 12 torque? O.o

At the same time, those numbers don't look bad for an M6 with H/C/I. It's honestly kind of the average most guys make with those combos. Got a pic of the dyno sheet?

 

i will get it tomorrow. i bought the car off the coast and live in a 2500ft elevation (spokane). i am ordering a wideband in the next few weeks. just havent had much time to play this summer with new baby (3 months early) i was hoping with all that this car should be able to do at least 480 to the tires with a good tune. but..........

 

480 to the tires requires some good heads, factory ported heads usually don't cut it. I'm not sure how (in)efficient the rear in the GTOs are either, so that may make things more difficult.

 

Those numbers are completely normal for those mods

 

Those numbers look good.

 

what would be the best course of action to get the torque up there around 450-480 as well as hp up. besides spray and boost? ive researched 383 kits but they honestly dont seem worth it when you can just find a 6.0 block and buy a kit for the same price and have 410+ cubes.

 

I would worry more about your way low trap speed as opposed to dyno numbers

 

I agree. You should be around 116-118.

 

Like mentioned above, see what it traps first before making changes

 

Those are good numbers almost exactly like mine.

 

The elevation probably has more to do with the low trap speeds than any mod done to the car. Most people don't run engines at that high of elevation, so it's difficult to speculate what it should run.

Is there a place you can run it near sea level? That would give you a better comparison. Then, you would know if you are on par with the others or not.

 

car has stock gears i should of said. yes spokane is at resting altitude (well the track anyway) 2600 and some change in the summer however i have seen corrected all the way at 5000 the day i ran was about 75 degrees out so probably 3500ish feet. its about the norm up here. yes i figured at least a 112-114mph was in order.

 

2000 ft isn't all that high. In spring/fall he can still have decent weather with good DA that is well below 2000.

at 5000 ft, i could see that much of a drop in trap speed.

 

Honestly I'm surprised you are worried those numbers may be low, 444 to the tires is damn good for such a simple setup. PRC stage 1's and a torquer cam making 444, I'd say that's above average. I've seen less power come from more money that's for sure.

 

i just wanted to see if i was on par or if there was room for improvement. i know i can get the car to ET better just takes practice. and we are closed for the season up here now anyway.

 

I'd be pretty happy with those numbers. especially in a stick car. That'd be fun as ****.

 

its fun.
