Badass and great numbers. I would love more info on the intercooler setup as I don't love the twin procharger units. Lol

BTW, I would definitely upgrade to some 1 7/8" primaries but 5K for 3" duals is just ridiculous. But with enough fuel, meth, and mentioned header/exhaust upgrade it will be even that much more impressive.

Ya, 5K was custom made 2" primary headers with dual 3" exhaust with X-Pipe. All in 304 stainless. The only problem is they need the car to do it. I think the price is fair for being done one off. Just hurts a little.

The guys at Kook wasn't sure if 1 7/8 headers were enough.

What brand is everyone else using. Thought about running the Ebay knock off 1 7/8 headers. But, I like to buy American. Not a fan of people copying company products in the states and getting them made overseas. But, 300 bucks is very intriguing.

Thanks.

Its great seeing it finally make the #'s I new it could make.

The way the graph looks I think it will peak at 925 to 950 RWHP. Since the goal was 800 I am so happy. Cant wait to get my IC1000 injectors in.

NICE #'S

I'm sure with larger headers & a good 4" merge you will see further gains.

good luck

Only time will tell. Here is the dyno of 891 RWHP that we did today. Will be getting some new injectors tomorrow. Also, I think I am almost at the end of my twin 255lph pumps too.

I see this is without Meth, can you tell me what fuel you have in the tank? I would like to get anywhere near 800 rwhp on pump fuel. 92 oct. here in the PNW

So here is what my intercooler consist of.

Vortech Prototype Air to Water. I think it is 1600 CFM
CX Racing Heat Exchanger its like 28x12x2
Chisled 5.5 gal Ice tank w/ Rule 2000 pump
3/4 lines

On these runs I emptied the tank a little less than half. Thru in 20lbs of ice. Intake air temps while cruising were between 60 to 65 degrees and hit mid 80 degrees at full throttle. The dyno was reading ambient air temp at 91 degrees.

I mounted the intercooler in a burkhart bumper support DIY kit. Along with my meth.

Really nice numbers. I think going to a 2" primary would be a good idea. Although I would see 2k on just those alone lol.

I was so excited that it hit over 800 that I forgot to video. I have a video of the runs before when it did 740's though. I will try and get those posted up.

This car really woke up when I switched to the Trickflow Heads from TEA and the Solid roller from Golen. Also finally getting a real ECM helped a ton too. The kit from EFI connection is amazing.

Thanks.

So I found out that I can gey a DIY header kit from stainless works for about 900.00 with slip fit merge. Just not sure what the gains really are going to be.

Is it going to be 50 plus RWHP. If not not sure it is worth the effort.

Whats everyone else's opinion. Not sure if its worth it?????????

damn bro post up a vid.

also I think your twin pump setup is very close to max out. They will cut out at 950 max and I have seen some cut out closer to 900. As for the header setup, I would do ebay kooks knockoff with 1 7/8ths and get a merge pipe to run from the headers and make a new y pipe from a 3" to a 4" exhaust out the back. Dont the x pipe and just make way with the merge and 4" setup
