If it was me i would just build it.. I wouldnt take the chance of waiting and blowing your motor and risk damaging your supercharger and or your heads.. Some have made that on a stock motor safely and others have blown with less than that..ahh i see.
So is it 400HP or 400RWHP?
I took a ride in a Supercharged mustang this weekend and well, now im thinking i need to speed up my plans for the car haha. I want a minimum of 430RWHP.
If the heads are strong enough then i'll just leave those.
How much am i looking at for rods and pistons?
Do you guys think i should Build my engine first or should I just get the supercharger and get a Safe tune and then save up again to do a engine build later on?
i agree, there are a few things that will effect what'll happen. 1)tune/combo-with a bad tune or trying to run 14 lbs of boost on a stock motor, chances are it's not going to last. 2)How you drive it-If the boost gauge is pegged all the time, you're on borrowed time. 3)Maintenence-If you don't change your oil on time, etc...you're on borrowed time as well.i think it has alot to do with how hard the car is driven on a day to day basis, run boost all the time its gonna blow but but if your careful i would say it will last...
Damn Baker. Me and you need to have a Sit down and talk. haha. Soooo you have 147,000 Miles on your Motor? thats crazy, and you motor is holding up at 427RWHP. that awesome. All you have to your engine is Cams and the Prochager and a couple other bolt ons in your sig. seems pretty easy to reach 430 then...you could run 450rwhp as long as it is running efficient. Ported heads, good cams 10 pounds of boost, few bolt ons. youll be over 430rwhp. Unix is running 470rwhp on his stock shortblock with just cams and d1sc and stock heads. As much talk about the "weak rods" that i hear, i have yet to see a post about a broke rod. I have seen ONE where a piston went to **** but not a rod yet. Im at 427rwhp at 9-10 pounds with 147000 miles and have some stage 2 heads sitting in the garage. There is no DEFINITE number on the stock shortblocks power levels. The tune will play a VERY big part on its life.
An efficient 440rwhp (ported heads, good cams, LT's, etc) car is way better than a car with 15 pounds of boost to hit 440rwhp.
what do you mean by pegging? sorry...i agree, there are a few things that will effect what'll happen. 1)tune/combo-with a bad tune or trying to run 14 lbs of boost on a stock motor, chances are it's not going to last. 2)How you drive it-If the boost gauge is pegged all the time, you're on borrowed time. 3)Maintenence-If you don't change your oil on time, etc...you're on borrowed time as well.
powdered metal rods are considered forged...so I don't think those are stock. I thought the stock rods were cast iron and thats why they were junkrods are powdered metal and are junk, pistons are hyperutectic and the ringlands can crack fairly easily with too much power/psi. i've had 2 pistons go off at once with broken ringlands. car still ran though sparkplugs were smashed flat lol.
