Easy engine setup for 1000hp?

[jhatley7]

He's has the worst luck. I'm surprised he's still building either of his GT'S with all the troubles he's had. His thread is staggeringly frustrating and it's not even my cars

i woulda prolly given up by now also lol.

It makes me sick to think how much money that man has lost. Fuck that.

I am making lower 900's depending on dyno with my whipple setup and 21 psi. My motor was built locally by Brett Lasala. Basically coolant block off supports, 90lb springs, mahle pistons manley rods arp everything upgraded oil pump gear and crank sprocket.

My motor did recently start clacking and I'm in the process of pulling it out; it doesn't sound major; sounds like something came loose in front like a tensioner or something. Its hot here, so taking my time, but motor should be out within the next week (only working a few hours on weekends).

I have also been chasing making 1000 wheel with my whipple setup, but I don't know if the whipple can handle that much. I'm right now debating on doing cams while motor is out to see what it makes. But even on a good dyno where I make 930 wheel, add say 40 to that for cams that would be 970 wheel. So tossing up which direction to go.

At 21 psi twin turbo's would put down 1,050 plus rwhp.

Yes. I'm contemplating. Cams will cost me about 1500. Or I could say sell the whipple for 6500 or 7k and put the rest into the twin setup. But then I need intake, not sure if I would keep the 20 percent od balancer or put stick one back on.

Don't know anything about the turbo game. Really like sounds of digital boost controller, but where would I mount it? Also considering what safeties I would need. I hear of boost leash, not sure what else is out there. Don't want to get in over my head.

Size matters, Whipple 2.9L is rated at 1800CFM. A 4.2L Kenne Bell will make 1400whp at 21 psi. What's your point? Twin 55mm turbos will make 700whp at 21psi, twin 98's will make 2500whp. I don't get it

Going down the turbo rabbit hole now. Adds up pretty quick. I still say cams and port polish should get you to the 1k mark. And if you still decide on turbo atleast the head work is already done.

My point is that blower motors need to be built up with all the bells and whistles, and you are constantly running them on the edge to make power. Turbo's make power on motors with less modifications and they make more power period. If you had twin 55 mm turbo's and you only made 700 rwhp at 21 psi you have no idea what you are doing, and in the real world a 4.2 KB would never make 1400 rwhp on a 5.0L engine @ 21 psi it would take more like 30 plus psi to hit that mark.

I have had many blowers in my time and I've had every Whipple from a 2.9l to a 4.5l, I've always wanted to do a turbo setup. I have now taken the plunge and have ordered the Boost Works kit with twin 62/66 comp turbo's hoping to make more power with less boost and no strain on that tiny 1.250 inch crank snout with a undercut radius.

Twin 55's are going to easily make 900+ on 21psi, my 62's make 1060/978 on 22psi.

Doodguy, if you want the #'s then go for twins, don't mess with cams. If you want to go really fast then install an auto, keep the whipple. Twins will role out with an auto as well. Get your motor fixed, keep things simple, don't get caught up in dyno #'s.

Either way, your suggesting against cams?

Thanks for advice! I keep wondering if twins would feel faster. The whipple hits hard and holds. But I can sip tea when I step on it. At the track it feels fast but on the street doesn't feel so fast to me.

I imagine with twins as the power spooling up would be more the roller coaster type feel. Maybe I'm wrong.


I've been debating on switching auto. I like the control of the manual on the street. With auto I'm wondering if your info auto, you mash the gas for the downshift will it go crazy and want to go sideways?

Stock untouched heads can make about 1200-1300whp (turbo) if i recall correctly. I can't recall if that's just a light port with upgraded springs or completely untouched. Either way cams shouldn't be needed, most id do is porting and upgraded springs in my opinion.

Stock untouched heads can make about 1200-1300whp (turbo) from my understanding. I can't recall if that's just a light port eith upgraded springs or completely untouched. Either way cams shouldn't be needed, most id do is porting and upgraded springs in my opinion.

thanks. I have 90lb springs. I've heard mixed reviews on head porting. I know one thing it's pricey! Not saying the amt of time andrew work involved doesn't justify the cost. It is what it is.

I'd send your heads to RGR for ported heads before I upgraded any cams. Ive not heard anything bad when done correctly.

Not the case with the Whipple 2.9. I've only seen one 2.9 break 1k. It's was with a s197 with head work.

Hense why I'm going twin. Mor powa!
