How much WHP to expect with these mods?
 

Kooks Headers,Flex Fuel,CAI,Atomic Force Intake Manifold.

Im thinking this is all I’ll need to satisfy me power wise right now I’m bone stock but this is the route I want to go with maybe an exhaust way later because the stock npp sounds pretty good.

500whp is where I want to be with no Crazy Engine work or any forced induction system.

Anyone have a similar setup wanna share their numbers?

I have msd intake, rotofab cai, kooks 1 7/8 headers, 95mm tb, no flex as we lack e gas here but had it dyno tuned by jdp and it made 460 whp on pump. Im pretty happy but i go back for heads and cam here shortly

~480ish rwhp would be my guess with a tune and running E

460-470 rwhp is about it in my opinion for a reliable, repeatable tune and not a tune that is just for bragging rights.

I think you will like the headers and factory NPP sound. I left mines alone with the h/f cats and its nice and loud. You already paid extra for the NPP
changing it would be like wasting money.

I have the headers, h/f cats, and npp and like it as well

Yeah I was thinking Trifecta for the tune

These 2 statements crack me up, youll be happy fot about a week then youll want more ..... the rabbit hole nvr ends but its a nice setup for sure. Then ull start worrying bout your afm lifters jacking up ur motor, so ull want to change them for reliability and peace of mind. But since ur in there need to do a cam too and heck why not a nice set of ported heads too 🤣🤣. Thats currently where i am but its ok the cars a beast and with the next mods itll be amazing more so!

An you wont go over 500 without a cam, N20, or FI, But you can get close and maybe you have more willpower than me an most and the fbo power level will be good for you.

Yesterday i was driving home and i was on the old free way (in mexico😏) and up ahead i see some bright orange thing with a wing. As i close in its a dam orange porsche GT3RS. I was like im goin to be squashed but lets see if he will play. Guy was actually pretty cool and a run from bout 20 to 110 we were dead nuts even. He may have been inching on me a lil but everytime his car would he had to shift .... my 10 speed just rowed through the gears. It was fun i was happy how my 1LE did with fbo but all i could think was if i had only already had my heads an cam 🤣🤣🤣

i had:

2" long tubes
rotofab dry
untouched msd manifold
untouched LT5 tb

dyno dynamics car made 419 on 93 and 441 on ethanol. trapped 125+ on ethanol. full weight 2018 ss 1LE.

i added a ported msd manifold and ati damper. car picked up another 1-1.5 mph. no dyno numbers.

Only 20hp seems kinda low for those mods

20 hp?

Dyno dynamic reads real low so dont be fooled his.125 trap tells real story

Yeah, that 125 trap tells it all. My dyno results untouched LT2 intake, solar 91 mm effective ported TB, opened up stock air box, E70 and borla S touring mufflers, full factory exhaust back to the mufflers, 421 on 93, 440.6 on E70 and my best trap 122 mph. I would think it would take another 25-30 hp to trap 125

Dead nuts on guess my best has been 126mph and thats 93 octane and fbo. Wish we had E around here dang it. Im stocked for my heads and cam hate waiting
