i got three pulls today on the dyno

126.6 @ 6800 with about 100 ftlb of torque
just wondering if thats good or bad for a stock GXL
new exhaust soon to come and ill post the difference.
thanks

 

I have a stock S5 GXL and I always woundered what they made on the dyno to the wheels. How many miles do you have on the engine, do you know your compression? Also are your 5th and 6th AUX ports working?

 

yeah they work not to sure on compression but i know its good. the engine has 70k org and they were very smooth pulls. no white smoke, popping etc.

 

That's not bad at all!

 

If his aux ports weren't working there's no way he'd be making peak power at 6800. When mine were stuck closed on the dyno I made peak power way below that.

 

thank you thats what i was wondering. i told a friend that and he told me it sucked so i told him to put his 7 on and see how it does

 

better than a stock civic...

 

i think there is room for improvement...my friends '86 gxl made 134.4 with just an exhaust...everything else was basically stock

 

my exhaust is on its way! hopefully this weekend i can put it on. then im gonna run it again and see how it does. this summer hopefully new clutch and flywheel. along with many more

 

make sure you get a header too! i've heard they noticably raise the HP over the stock exhaust manifold. intake/header/exhaust should be atleast 135-140whp for you.

 

yes im getting the rb header to a highflow cat (for now) then the rb cat back. maybe later i can swap the cat for a straight pipe.

 

just get the straight pipe if emissions is no big deal

i had a cat with the rb header and rb catback. I took out the cat and replaced it with a straightpipe and I noticed very little difference in loudness... that cat may have smoothed it out a little bit but that's it.
