Kenne Bell 25 lbs on 03 cobra w/ 69k miles?

[03SonicBlueYERMIND]

My 03 Cobra has 69k miles. A CLEAN title, all and any recall items all set. theres a lil bit of play in the driveline witch is expected at this age, but taken care of well. I run 18 lbs boost now with a stage 5 ported Eaton. I want to simpily place one of the kenne bell blowers on and call it a day. I got the BAP, 60 pound injectors and bigger throttle body. Basicaly i wanna know if i wont grenade the motor. I RARELY boost or go past half throttle lol. Thanks so much for the input if any!


UPDATE 2/7/12- I think I will do a whipple or K.B. and actually lower the boost to about 16-17lbs. I will gain hp aswell as less strain on my pulled ported blower I have now... and that's that! I'm hoping to go from 470 RWHP now, to about 525-550 RWHP- still on my 93 octane tune.. Maybe 575 RWHP or so on my 100 octane tune. Veryyyy exciting!

well unless you plan on running a 2.8LC then 25lbs is going to be a no-no

Well that is DEF. the plan. aswell as the 1 1/2 inch Steeda springs, subframe connectors, IRS brace, and an all new bushing kit. i THINK the rear will finally not hop and hook, but i wanna make sure that engine can take it

The engine will take it....the key is to have a GOOD Tune!!!!!

I'd think even with a BAP, you'd have to upgrade the stock pumps to at least the GT pumps...Without E85, you'll be fine with the 60# injectors!

^ Agreed...

From the title of your post you plan on running 25psi? Stock pumps and BAP are only good to about 630-650 rwhp. With a big blower and 25psi you will be pushing nearly 750rwhp...at that point the 60's would probably be out of steam too.

Soooo I think that I would run 18-20psi with a better blower. Safely making 500-550 rep I'm hoping with my set up

You should be there with your eaton and 18psi. Any twin screw at 20psi will get you in the ball park of 600rwhp.

You may still end up needing to upgrade your pumps though. I have a friend with a 2.9L Whipple that made 621 rwhp with a slipping clutch and the stock 3.50" pulley...He was only seeing 16psi and guess what, he was maxing out his stock pumps and BAP.

I know every car is different and some people get more out of their setups and others not so much. It would be safer to upgrade your pumps and injectors. Not to mention there is always that urge to run more boost. With upgrading your fuel system, you'll be able to do just that!

Upgrade from 60 lb injectors to bigger ones? I'm realistically trying to just make maybe another 50-80 rwhp by adding a 2.3 whipple and running 18 lbs of boost.

Any particular reason why you want to run 25lbs of boost? Are you planning on taking the car to the track at all? The motor will not live long on 25lbs and you'll need to run race gas all the time which gets pretty expensive for a street car. These cars are mid 10 sec cars on only 17lbs if you know how to drive them.

Don't listen to the dyno queens that want to brag about a dyno number. They won't be the ones paying for your new motor...

Ok, so now you're going from a KB running 25psi to a Whipple 2.3 at 18psi. You'll be fine with 60lb squirters and stock pumps + BAP. You will also enjoy your stock motor for a long time with that setup as long as you keep plenty of octane in the tank.

Yeah I have researched this a bit more and I adjusted my original post haha. I will run 16-17 lbs of boost with that bigger blower on 93 octane and tune and look for maybe 525 RWHP after that new blower goes on and the ported eaton goes bye bye.

Yes sir that is the plan! Prob even 16-17 lbs on 93 octane and 2 or 3 lbs of boost more on a 100 octane tune. I'm looking into that 2.3 whipple or a k.b. right now

Thanks for the info aswell!

25psi save for a motor. I love the motor will take it, the heat generated at 25psi the pistons wont last long and without a spot on tune, race fuel and logging the car. Pack a shovel to clean up the parts. As Mike posted, 17psi to 18psi and a safe tune.
