He's already got 3" exhaust.

 

I have a 3 inch cat pipe w/ HI flow cat, and 3 inch cat back.

 

Good stuff. A 50 shot of nitrous is good for about 40 horses hah? That is nice.

 

isn't that too lean on your last run?

what n2o kit do you run, who installed it? any pics.

WTF is an AUTOMERGE DOUBLEPOST?

 

The sniffer is after the cat so it's going to read leaner. I think if anything I could probably lean it a bit more.

It's a zex nitrous kit and I installed it in my driveway.

If you make two posts in a row, it merges them together to prevent post whoring. It's pretty much your anti christ

 

things id check...that weird af dip in 3rd run look a lot like knock...the way it killed power then ramped in

Good numbers tho...I'd be worried at anything over 90% idc....

Have the hpt logs?

Dan

 

Zinner do you run a header now ? Still nitrous in the car ? Stock clutch ?

 

wow zinner didn't know you tuned at promotion. where you at? should hang out sometime or some ****

 

wow. back from the dead.. at least you picked a good one

 

Sweet!

not too many juiced balties out there. i'm happy some of us choose to.

 

im jealous...nice pull man!!!

 

Awsome stuff! bet you can't wait for the track?

 

how has it held up zin?

 

FNFAST with GM stage 3 and a 50 shot dry pulled a 307hp on the dyno

 

I think zinner had no header on this dyno chart ?

 

correct

 

FNFAST only had a aem intake on his I think.

 

have the pe changed, this will bring the low end up a bit.


also, whats with the old threads comming back to life?

 

love those numbers good job

 

gotta love the torque nitrous provides

 

Let me check back in. These number are with a stock header. I didn't get it tuned at promotion, I just went to an East Coast Boost Dyno day to get the discount.

I recently went back for another dyno at Promotion with a 75 shot and 2.8 with header and put down 307 whp. I think I could of got another 10 hp because I backed down the timing for the 75 shot. My baseline is 202 WHP on this car. So I was about 105 + gain with my mods. I don't think the header made a lick of difference, supported by the dyno.

The car is still running great and the stock clutch is still holding on I have a progressive controller now so the nitrous is a lot smoother and you can't tell it's even kicking in now it just start pulling harder as the revs go up.

When I did my latest 307 pull, the engine rocked foward so much the dipstick tube hit the radaitor support, cracked at the support on the intake manifold and shot oil all over the dyno

I ended up putting in a new dipstick, intake manifold gasket and my ingalls dampener. Problem solved.


The AFR reading on this dyno reading is about .75 of a point lean.

Here is the latest setup picture.

 

i just bought the stage 3 kit. Im waiting to get the parts for the dual pass, then a nitrous kit. Id like to tune it myself aswell. Im probly gonna get the valve springs and balance shafts so I can use the 8k redline too.

 

no video

 

Nice numbers, Hey is the GMPP Stage 2 upgrade worth it?, I only ask cuz I'm workin my way towards a stage 3 eventually.

 

have you been able to take it to the track zinner?
