*New Dyno results for my Fresh Teksid build KB 2.8H Mammoth* (Video inside)

[Sweet '96 Cobra]

I just completed a Teksid build about a month ago. So while I was at it I stepped up to CNC ported heads and BBK longtubes. Other than the things mentioned above the setup is the same. I put down 615rwhp and 514rwtq on 18 psi and 679rwhp and 576rwtq on 23psi. Those are SAE corrected numbers too, I might add. The tuning was done by Performance Dyno in Loudon NH, and I must say Pete is the man! only took 1 pull to get my 17-18psi tune and only 2 to nail down my 23 psi tune. There is still a lot of room left with this Engine we think, but for now this should do. That KB Mammoth wants to spin even faster, I can tell.

There was 950 easy break in miles on the engine at the time of tuning. Mixing Torco with 91 octane.. 91 is all I can get up here where I live...

Congrats! Pete's the best :rockon:

E85 an option down the road?

I dont forsee E85 here anytime soon here in the Great white north. Whats crazy is that I was able to accomplish those numbers with twin Focus pumps, KB BAP and 72lbs injectors. Other than those fuel mods its stock setup and Pete said theres still a little room left but will probably have to upgrade the stock MAF if I decide to up the boost anymore.

23lbs\679whp and your on the stock maf?? I don't understand how that can be possible. I'm almost pegged on my setup in my sig

The key is the 4.5" Mammoth inlet pipe compared to the stock air intake, thats the reason why according to Kenne Bell.

Great setup!! My car was tuned by Pete as well and runs very strong. Similar setup but I have a 2.9 Whipple. All we have here is 91 octane as well which sucks.... Car should be a monster on the street!!

You must have a MAFia on there right? Im on my stock MAF as well with a MAFIA

I'm at 714/680 with a stock maf with mafia. Stock inlet tube as well. 9" amsoil filter on the end. Plenty of room left

Great #s op

Is your setup return or returnless? If you didn't have the BAP your duty cycle would have been maxed before you hit 680RW with the twin Focus', haha! Nice #'s..

 

[R.D.P.]

I don't think he means he's running a MAFia - I think he's saying straight up stock MAF, that's why I said I don't understand how it can be possible. I guess the tube diameter really has a huge impact on it.

No MAFIA, just my stock MAF mounted on the Mammoth inlet tube.. the 4.5" diameter pipe is the Key according to KB.

Im at 649 rwhp on my 2.8kb manmoth kit. Stock mass air also

 

[MTBSully]

Damn, how long was the drive down to pete from where you are?

Damn, how long was the drive down to pete from where you are?

It's about a 7 hour drive each way, just under 1100 miles. Drove the car too! No trailer!

Too bad ... E85 would be your friend!

That's awesome that you drove it down. Hopefully your a thin guy and the stock seats are your friend. I can only do about 3-4 hrs myself.

 

[Shadow Grey 03]

I'm guessing stock electronics in the big tube and not the 90mm maf bolted to the tube. I may be wrong.

Congrats OP! My old tuner used to keep my stock MAF too. Whipple 2.3 and my whipple 2.9 stock maf over 600 rwhp. He would adjust something, he always told me not to spend the money on a maf. Never had any issues and no mafia.

The MAF works using a simple hot wire method. The actual reading from the MAF is linear speed, not volume. You then calibrate the ECU for the diameter of the pipe to get volume. When placing the MAF in a much bigger tube you are essentially reducing the linear speed of the air and therefore the reading for a given volume of air, giving you more headroom for the sensor.

Haha...I was ok with the seats, I found the Cobra fairly comfy actually.

You are correct.

Thats a great explanation.
