need background info
Im sorry if this was brought up somewhere else in the forum but I was looking into either supercharging my 2002 mustang gt or replacing the engine with a 351 Windsor in the fall.
I really like the Kenne bell twin screw superchargers and see that they have kits for around 4 grand and I found a 351W crate motor on www.yearone.com for 4 grand. They both make around the same power but i didnt know if the 351W would involve alot more money for supporting parts to make it fit and/or work.
Also my car has 74,000 miles and is it a smart choice to supercharge it with that high mileage? Any background information will be greatly appreciated.
Btw...my goal is around 400rwhp

As long as your car has been taken care of, and the system is set up properly, you should have no problems supercharging a car with 70k+ miles. BTW (and I know this is a stupid question, but..) is that 351 a carb engine, or do they set them up for fuel injection?

You're really not going to be able to use a 351. I assume your state does inspections and yours should require an OBD2 inspection. Other than that, you'd at a bare minimum need a K-member with the correct motor mounts, fuel system, If you were going with EFI you'd basically have to use a stand alone system, and a transmission.

Why swap for a Windsor? It's easier to do a 5.4 swap. However, if you want pushrod, get a Windsor block and throw Cleveland heads on top to make a real performer. Just remember you need to get a EFI manifold so that you can still run EFI and pass emissions. The only thing electrically I'd worry about is the pump may need upgrading and the computer needs to be re-calibrated to deal w/ 351 cubes.

You will spend money money to get a 400rwhp 351/302 motor into your car then it costs to add a supercharger and make 400rwhp with the 281 you already have. The kenny bell,Procharger,Novi 2000, and any other power adders out there will push the stock motor to what you want to make power wise and that is also around the max power for the stock 281 motor.

go with the suercharger
I'd definately go with the Kenne Bell. It will be a lot less work for sure and a lot less fabrication and all for the same cost. Actually the supercharger route will be a lot cheaper in the long run bec. you will have a lot less parts to buy to support the swap.

Ok I will look into the supercharger more. Another question I have was if the kenne bell kits without the intercooler overheat alot and if its a good buy. I live in southern PA so the summers get a bit hot but nothing more than 95 degrees or so. Just trying to figure out if the extra grand or so for the intercooled kits are worth the extra money

Ok another question was what psi would be safe to run on my stock motor. The 9 psi kit thats intercooled is just in my price range but I don't know if that would hurt the life of my engine or require me to upgrade my internals (which I don't have the money for).

the 2.1 KB 9 psi kit will put you at 400 hp. thats a good number to be at and thats a good and safe amount of boost.
I been running my stock block at 12 psi for nearly 30k miles... i have 92k miles on the car now.

Alright thank you for all the info. Does the 9 psi kenne bell kit come with everything ill need and how hard is that to install it?

yes the kit comes with everything for you to start up and boost away...
install is up to your mechanical skills. im a mechanic in the air force so a job like that doesnt really intimidate me.

And if you do not want to spend the money on a KB kit then you can look into ProCharger,Vortec,Paxton all make nice centrifugal supercharger kits for your car too that make good power.
