Stock flywheels/big power
I've been buttoning up my procharged 540 getting ready to dyno in a few weeks,i'm expecting to see around 850-900 hp. My question is for all you big power guys(jcperf,gpm,rlw,tomcat and anyone else making 750-1000 plus hp). I ran a stock replacement mk4 style flywheel on my motor for last 2 years with around 750hp/800 ft lbs torque w/xr style coupler,i spin motor to 6000 rpm's max,with no problems. Are you guys running stock flywheels,do they or has anyone heard of then breaking/exploding? Is it a must that i buy a billet flywheel? Sure,i can spend 300$ on one for piece of mind but is it really a non issue?Thanks in advance for any input,Smitty

I don't see any need in it . On my Scarab blower motor I made 828hp and the My Hustler motors made even more .all stock heavy flywheels
I don't even here of anybody running anything different ?
Smitty what did you end up doing about a throttle body?

Summit sells them for about $230, how many dollars worth of parts will you loose if it breaks, where are all the pieces going to end up. I like the 25lb Hays. Good Luck on the Dyno!!

The manifold i have highly modified in a bridgeport mill plus i made custom fuel rails for the 63 lb injectors (they are 5/8 inch longer than stock). If it makes less than 850hp on the dyno i will buy a 1200cfm throttle bodie and open plenum intake. I just got the heads and pistons back from swaintech from getting full thermal coating treatment and the cam i ordered from rm builder also came this week. I have gotten 13 transmission jobs in this last week and a 1/2 so there hasn't been any time to put motor together,today i left the phone off the hook and worked on motor all day,of course the timing chain doesn't resemble a big block once it came out of the box so i have to re-order that Monday! Anyways,hope to be on dyno by may 15th,Tom Robinson plans on meeting me at Crocketts shop so he can see his Dyno in action and the programing for the 63 lb injectors so it oughta be fun! Smitty
Smitty good luck on the dyno . hope ya get the #'s.Yea I hate getting the wrong parts . Just was there with pulleys
Jeff I guess I really do need those diapers for the flywheels uuh
Have yall seen one of these come apart?I would think it would be from vibrations or harmonics???

What's the point in running a $75 flywheel on a $20000 motor.
