Steve,

If you dont get greedy and stick with 6psi + dyno tune (conservative A/F & timing), you should be able to get a good amount of use out of it. Its all in the tune.

It's only a matter of time before it grenades, the tune will help but I've seen em grenade pretty quick even with a good tune

 

S-trim @ 6psi for 20k miles = BOOM!

 

seems like you guys are getting decent millage out of them, if i do it, im gonna be building a 355 for when it goes. i just want to make sure i could run it for a while so i have time to finish the motor. i was gonna do a forged 355 and just put on stock heads and cam. only really looking for 450-500 to the wheels with the new motor, nothing crazy.

 

Hey Brian, how do you like your 224/236 blower cam? I getting that same one, but only in a 355 cid.

 

LS1's typically, 9psi, 650 rwhp, running 9's....breaking point for stock bottom ends.

Not sure about LT1's, tho....If you ever take the motor out, look into some upgrades....mabie a bore job...the LT1's make nice torque...

 

It's very streetable and pulls hard...but unfortunately I keep having tranny problems and misc gremlins that have prevented us from seeing it's full potential yet. It sounds good and feels great so far though.

 

Build the Engine......hands down. If you have 3-6k to drop on the blower you can drop it on the engine instead. Probably making more power then your stock engine with the blower would have made. My vote is for the engine.....

 

Im in a similar situation, working on a 383 forged setup and have a stock bottom lt1 in the car now with a blower cam, but i fear installing the blower because its going to be at least a year b4 i finish the stroker. Thinking I should just leave well enough alone and wait til the stroker is done instead of bolting the blower on the stock'r although thats what was originally intended while i build the stroker. I drive my ride hard, and i dont think it will handle 6psi long the way i drive. The stocker has a cc305 on a 114 lsa, 58TB, LT's, and 1.5 RR's. I need more speed, but if I blow the stocker, she sits until the stroker is done. I know shes gonna go BOOM,....but the temptation is still there, especially when you have the SC kit sitting in the closet. Maybe I should just sell the kit and use it to fund the engine. Anyone want a 4.5 psi PD kit with a 6psi pulley and a 7" crank pulley?

 

hey man, im looking to sell my 6# vortech V2-SQ with aftercooler kit. its only got about 200-300 miles on it. im selling everything, brackets, crane HI-6 with ignition retard, FMU, t-rex fuel pump.....vortech advertises that its good for up to 20psi when pullied to do so....

hit me up if your interested. i dynoed over 400 rwhp with stock bottom end........

thats why im selling it, i dont want to build a new motor and i only drive the car less then 1000 miles a year...just dont need the SC.

i would if i had money, but i got not money cause i bought a dirtbike. i would have to ditch the dirt bike and see if i had enough, pm me what you want for it,

 

Heres a link.....

thats cool, what kinda bike did you get? i raced when i was younger....i ride an old 1999 YZ250 now for fun. it still runs real strong, and ive got money into stuff like wheels (kept blowing spoke nipples off the stock wheels), bigger brakes, suspension work etc....and if i ever buy a new bike id have to at least upgrade the wheels and suspension and thats too much money. dirt bikes now days are as much as street bikes used to be!!!!

jeremy

 

i have a 95 cr125, so its now worth enough to sell to buy the kit off of you, lol

 

i understand. when your ready, keep me in mind. i still might have it. and it still wont have much use on it......
