Fast 102 or Maggie MP112 to top it off with stock internals?

 

Not sure what the question is?

 

FAST or nothing. Boost with stock internals is stupid.

 

Seriously?

About the maggie though, that cam has way too much overlap for a small magnuson supercharger. If it was a big centrifugal or something that didn't mind the overlap, I'd say go for it. Not with that blower though.

 

I see this as someone looking for blind praise on his ignorant choice of catalog parts.
Catalog kits like that are rarely worthwhile even if you use them as the manufacturer intended which you wouldn't be if putting a supercharger on.......................

 

What cam would you suggest or dump the maggie and use a 102mm FAST?

Thank you for having critical input.

 

You understand the difference between the 515hp kit claims and what guys post here right?

Most guys are better off with ported GM heads than they are with as cast aftermarket stuff.

 

my options are endless, just looking for positive input or suggestions. My budget is also not an issue here


so if you think

I'd be better of with LS6 stage 3 heads forged eagle/lunati/scat internals with diamond or wiseco pistons and torquer V3 or Magic stick cam or a TSP 220 go ahead and tell me. I'm shooting for 550rwhp with heads/cam/exhaust and a root style supercharger.

 

To be honest it seems like you need to do some more research.

Anyone of these cams you mentioned are not even close to being maggie friendly at all. Its ok to have more lift with a mggie on a cam but you dont want crazy duration. you also should run a wider LSA with a maggie.

You arent going to make 550 to the wheels with just Intake heads and cam either.

As for heads it really depends on your setup and what you will need. You should get a better plan together then just wanting 550 HP.

 

If i were you i would consider calling up one of the sponsor on this site

 

With the TFS heads, cam and 102 setup, you'll be ok, but I would suggest milling the heads to get to around 11.1 compression. Forget the Maggie for now.

 

The stock crank is pretty bulletproof so even if you decide to do forged internals no need to replace the crank.

 

I was shooting for a bout 475-500rwhp all motor or 550rwhp+ with the supercharger so ditching the Maggie my goal is 475-500rwhp.

 

thank you for the positive feed back

 

what short block do you have ?a stock ls1 , with TFS 220 cast heads ,fast 102 intake ,and a 226/234 EPS cam mite make 470 rwhp.what rear end and tranny do you have ?vengeance racing sells a nice TFS cam/head combo.also look at AFR 210 heads with a Tony Mamo cam.

 

I have customers making 470rwhp/420rwtq with TFS As Cast 220's, Fast 102 and mid 230's duration cams. One in particular had 1x3/4" headers, 85mm MAF, True Duals and an underdrive pulley and made 468rwhp/417rwtq with a 234/239 112+3 cam and 11.4:1 compression on 91 octane.

 

I have a completely stock Ls1
I have a 4l60E with TCI master rebuilt kit,3200 stall,10 bolt with 3.73s. Gonna get a 4L80E with a 12 bolt or 9" with 3.73s.

 

OP, in all seriousness you need to throttle back with all your plans your spouting off and do alot of research. most of your plans do not work well together in the parts you are selecting. also it seems that you are building around a simple goal of wanting 500rwhp. question, have you ever ridden in a 500rwhp car? what about 400rwhp? cars with both these numbers are capable of running the exact same times in a 1/4 mile race. HP doesnt really mean much, it is a unit of measure created by man. torque is a real value based off pyhsics. and 1/4 times speak for themselves. start slow with your build, simple bolt ons, intake and exhaust, and go up from there. figure out what it is you want and if this will be a street car or a drag strip car. is it going to be a daily driver, how much do you want to put into it and what times would you like to run in a 1/4? figure these things out first. you will find that even just 400rwhp in an f body may be all you want and you will run the time you want. 400rwhp would probably impress you as it seems you dont have much time with cars like this based of how you post. seriously take my advice on this and do your homework and do not buy XXXhp kits. if all you want is a XXX hp dyno queen then by all means throw whatever you want in there or just pay off a dyno guy to fix the numbers. if you want real results and a well performing street car/track car then do your research before you throw parts at it and the payoff will be better. good luck

 

I think the first thing you need to do is put aside some savings to redo the tranny and likely converter. The 4L80E is not necessary but a much better build of the 4L60E is.

I would agree with the comments about how much power do you have experience with. 450rwhp with an OK but not great start should solidly have you needing a rollbar at the strip. With a good start should net 10s easily

 

With 425rwhp/380rwtq through an unlocked Th400 and a 5900rpm stall, 12 bolt w/ spool and 4.11's I was able to go 6.38@104.5mph in the 1/8th mile. That equates to roughly a 10.05@129mph in the 1/4 mile. Granted I was at 3000lbs race weight and consistently cut 1.29-1.31 60's and consistent 4.05-4.10 330' times.....but it is possible with even less power than these guys are telling you.

This was a cam-only set-up with the only power adding modifications being the camshaft, ARH 1x7/8" headers, a Fast92/96 and a 4" cold air intake plumbed to the catfish mouth.

If you'd like to find a solid direction to take with your build give me a call tomorrow@336-719-0599 and I'll get you straightened out and on the right path.
