Ported 6.2 Manifold

[NORCAL SS]

Just a heads up guys I will be doing a dyno run before/after the ported manifold I ordered from Peak speed shop for my 6.2 Escalade.

• I'm going to dyno my Escalade with just volant intake/3.5 inch magnaflow muffler swap/ported tb and tune on the 20th.
  

 

• I then will run the truck the 24th down the 1/4 with the above mods.
  

 

• Will install the ported manifold the week after and set up a dyno appt to see how much I can get out of it.
  

 

The truck is at the dealer now and rear end 9.5 is whining with like 3000 miles on it so they are pulling the gears and I asked for 3.73 gears to be swapped in which they are doing for me (I think im the first idiot that put 3.73 gears in the 6.2 escalade lol) The truck should launch nicely with the gear swap and would be nice if it ran in the 13s with 24s and a few mods.

its 425 and makes 12-15 on the car ones they do but no one has yet to try it on the 6.2 so Ill see how it does.

Wow Norcal, I don't think I know anyone that takes modding as seriously as you! I really enjoy following your progress.

Any pics

[NORCAL SS]

Ill have pics as soon as I get the manifold. The 2wd esky is a lot faster than the awd one thats for sure. My buddy has bolt ons on his awd escalade and mine has still the stock tune and volant intake/muffler and I beat him by 2-3 cars everytime we race. Hes gong 14.60s in his truck also and this was with the 3.42 gears. I cant wait to race him again with the 373s in.

JUST got the manifold looks fkn killer!!! ill post up pics in 5.

[DaveH71]

Did you port the gaskets as well?

[NORCAL SS]

no but have new gaskets coming that I will line up and port match if needed.

[Gurrzt]

Have your new gears "cryoed" before installation, it will make them stronger to handle the increased HP & TQ.

[NORCAL SS]

putting in manifold today.

[NORCAL SS]

Before I go on guys get a catch can as your next mod will keep manifold a lot nicer.

 

ok so here we go. Overall the truck pulls better esp on the high end

If you're starting a pool on the HP increase, put me in for 6 HP for the manifold without any tune or other mods.

[SnakeEyeSS]

Hmmm, maybe some more than that. What are the gains seen on the LSXRT? Aren't.they like 15-20? I'm interested to see how this turns out.

[mjribeiro]

Does the LSXRT even fit on the 6.2L ? They don't list it as supported. Porting a stock one may be the only option.
