build motor -- or procharge?
 

what is your opinion on either rebuilding my current 200 hour 502mag mpi or adding a procharger?

it would appear the cost is almost the same to do either.

I'm looking to be around 580 - 610 hp

i see the tyler crocket setup would be about 7,000 and the m3sc procharger is about 6,500

obviously the one big advantage with the procharger is i can install it myself.

thoughts?

Best thing to do would be to pull the 502mpi and keep it stored and reinstall it when you go to sell. Build a complete new 600hp engine.

Lets see.....

For $6,500 you can have:
-200 hour motor
-Procharged with a lousy fuel system
-time bomb in alot of people eyes that not many people can work on.
-you have to do the install yourself

or for $500 more you can:
-have a fresh 600HP motor
-reliably built by a known builder
-write a check (for $500 more) and be DONE!!!!

Not sure I understand the question after looking at it that way! :cool-smiley-011:

LOL Done like you were? :D

that is actually what prompted my question -- i started thinking about it and was curious as to why one way was better than the other.

the only real good reason i could see to procharge would be to go more than 600 hp?

for me -- i'd be happy at 600hp.

600 hp
 

He gets you 600hp NA from a $7,000 workover? That is a pretty good deal.

When I looked at his setup it would net around 500hp for around $5,500. That would have been good for 5 mph. I went procharger with a 280 hour engine and don't regret at all. I got more than 10mph and after the reprogram my boat runs better than before.

I would do the 600 hp NA. Then you could freshen it all later, procharge and look out!

If 600HP is all you are looking for go NA, I have a procharged M3SC 7lb boost, injected modified 454. Yes it takes some homework I learned a little the hard way.
Don't ProCharge and not freshen your motor you will be doing it the next year anyway. Do it all at once.
Also consider drives a Bravo will not live long. The best drivers take them out.

Consider your real budget the weakest link will allways break.
I am happy with my end result. It runs with a B-Max at about 90MPH.

I had the same option last year. I went with the NA. I knew I wasn't mechanical enough for a supercharger and was going after more reliability. Superchargers build their torque at lower rpms so would naturally be a little harder on drives.

I like my procharger...I did have my engine built for it. I believe under normal cruising it is much more efficient Than a NA engine of the same power. Mine is a blow through carb setup...don't know about the headaches with FI. Ya do have ta get in the carb a few times until ya get the jetting right. Start out too rich and ease down. Waste a few sets a plugs,etc!

If you have the budget go for the whole thing. Myself and others can walk you trough it. I'm sure there are a lot of opinions regarding this but I would not do it different.
Feel the need for speed!!!!
