Decisions, Decisions...

WARNING: THIS THREAD IS PHOTO-INTENSIVE. I'D RECOMMEND AVOIDING IT FOR NOW IF YOU ARE ON A SLOW CONNECTION OR MOBILE DEVICE.


I cooked #8 on my stock motor (I must have been at or above 450HP with my 12PSI Vortech, never got around to getting it dyno'd...).

The real pisser is that it happened mid-summer and I can't drive it until I fix it. Would have been much better if it happened before the winter when the car is parked!


Anyway, so I am purchasing this Cobra pull complete with Eaton (everything under the hood):


I have a set of 60# injectors and a second fuel pump installation planned anyway, so the big decision to make is:

- leave my car as-is (plumbed for Vortech with air cooler), drop the Cobra motor in without the Eaton, and upgrade the pulley on the Vortech to bring it to 18-20PSI.

- tear out all of the Vortech piping, cooler, etc, and drop the complete Cobra motor in with the Eaton as it is.

I've never driven a roots-style blower before and understand that, while they're not as efficient as the centri's, the bottom end power is much better.



Either way, I'll have a complete supercharger kit up for sale at some point to offset the costs of purchasing this beast. The only way I was able to sell it to the wife was "almost breaking even" after selling off the spare supercharger and parts from the original blown motor.


This will be a great time to put on a pair of SW headers!

Nice find Joe! I say keep the Vortech and sell the Heaton. The best thing you have going for you is, you can show the potential buyer how the eaton works.

Good stuff!
It's nice to have options.

I will own a Mystichrome Cobra at some point in my life. If somebody offered me an even trade for the Marauder, I would not hesitate to hand over the keys.

Good find on the motor!

I have a T Trim impeller and a Cobra Long block. The only way I could get ~20K miles on the belt and eliminate slippage at 19psi was to go with an 8 rib.
There are pros and cons to both set ups.
I would get it dynoed before any wot.

I would stick with the Centri setup since the intercooling plumbing is already in place.

I've got to agree, as much as I love the Eaton swap, you're set up and ready to go with the centri; go for it!!!

Yeah and he certainly wont have a problem selling an Eaton swap!

For sure....

Drop the Cobra motor in, Eaton and all.

[CWright]

Heck NO,, I have had both setups! WHIPPLE that baby, you have plenty of motor now!

[dohc324ci]

Sell the Vortech (to me) and drop in the whole enchilada. You'll be ready for a Whipple of choice 2.3-2.9-3.4L!

[Vortech347]

Keep the engine and spin the **** out of the Vortech. It'll make more power and when a Vortech is spun hard they make plenty of low end boost. You could sell the Eaton swap parts for 2500-3k on SVTp and probably pay for the car and have a free engine.

[JoeBoomz]

Bah you guys aren't helping! Half say go Eaton and the other half Vortech!

The lazy guy in me thinks its easier to strip the motor while its out and change the front timing chain cover, then mount the vortech on. That versus pulling out all of the vortech plumbing and then trying to shoehorn the motor in (relocate the alt and notch the frame), and then re wiring all of the harness and everything to move the battery.

BUT the speed junkie in me wants an eventual whipple, which is a relatively easy upgrade once the Eaton is installed.
