Upgrade time [emoji16]

[2003SVTFreak]

So my buddy just bought a 2015 vette. He's already running his mouth about racing. I don't want to get beat, I have 03 cobra vert with 2.9"upper, stainless works full 3" with high flow cats, jlt big air, accufab sbtb, accufab plenum, all idler pulleys changed, tri-ax shifter, and a custom tune. I want to get a bit more power out of the stock eaton without porting. I don't have dyno numbers but know I want to be 500+rwhp. Looking for gurus to lead me in the direction to get this cobra to spank that vert. Thanks in advance.

even with a ported eaton the new vettes are fast and you have a heavy vert....i'd just go tvs


edit: you could throw on 2.75 pulley and do a fuel system and go e85 that would get you around 500whp without porting the blower

A TVS or whipple on pump will get you there. I bet just E85 on an eaton would too.

I was around 590rwhp and beat one that took the hit and had at least three cars on me.

Could always just run him now and see what happens.

Not related, but get rid of that jlt separator on drivers side and put that bigger one that's on passenger side in it's place.

I'm gonna run him at the track next week and we will see. I'm gonna get a BA2600, 2.76 pulley, and see where I stand. To run e85 I need to swap pumps and what else? Returnless?

Yeah the passenger side one has never caught anything in it. Might do that. Thanks.

Eesh the track will be even worse for you I think, unless he can't drive for crap. He auto or manual?

I know some guys have run E85 returnless. I can't recall all what they changed to be honest. Almost think I read factory lines, filter and everything, just appropriate injectors. I imagine it is more successful on an eaton car than bigger blower setups. Maybe talk to 04sleeper on here.

It generally doesn't. If your intake stays dry, just throw a jlt pre filter on that side.

I had the jlt on the driver's side year's ago. It's too small and doesn't allow all the vapors to break down. Check the back of your plenum/blower. See if you get any oil, I did.

It's an auto so his driving won't come to factor much.

You’re gonna be hard pressed to make 500whp without porting the blower

A fuel system will cost as much as buying a bigger blower....nitrous would be cheaper

 

[Rambro]

I used to hate hearing this because I was a big fan of the ported eaton........ For about a month lol. Try and hold out for a used 2.3 whipple. Ever since the tvs came out for our cars the 2.3 whipple can be had for super cheap. I gave 2500 for mine a few years ago and ive seen them go for around 2300 these days. Dont waste time with a port IMO. If your buddy does a cam and exhaust you might be in trouble with the port and e85, especially from a roll.

What numbers would I see with porting the blower and what's the cost?

Or should I hold out for tvs 3rd gen?

DEFINITELY wait for that TVS, porting a blower is not worth it imo, it’s half the price of a new blower and you’ll make 500 with a good port, and over 600 with any decent blower upgrade

 

[BlksvtCobra01]

TVS, return fuel, and E85. Was going to buy a ported blower but it’s not worth it. You will be hungry for more later. If your on a budget once the gen 3 hits the market there will probably be some deals on gen 2’s.

Have a E85 kit, everything you need ready to go, brand new, everything but injectors.
