Whipple-Cam-Headers = 700+RWHP !!!!

Our last cammed setup was with a maggie (makes about 30rwhp less than a Whipple) and at 8psi we made 610 on our dyno. With a whipple it would make about 640, which is 650-660 on a DJ.

So you made 610 with 8psi and a different supercharger. But yet 700+ with a better blower and 2 more psi and maybe a cam that works well with his set up is not possible??? Sometimes you just nail a set up and it makes power. Just because you set up didnt make this kinda power dont mean its not possible.

Your not going to be able to run this much HP and beat on it 24/7 and expect it to last 100k miles.

Your 100% right. Awesome build. I ended up leaving a lot on the table today on the dyno and got real close to those numbers or at then depending on what dyno. I just have blown shit up in the past. I'm being a wimp. Congrats again!

NOT disputing them....just can't figure out why mine is so low...only thing difft is...mine is running LS9 cam.

My a/f is 11.7
Timing is 14*

Dyno'd 600 rwhp.

It could be one of many things. The dyno you had your car on could be putting out lower numbers than most dynos, and RPM's could be reading higher than the average. The conditions when you dyno could make a major difference.
If you have an automatic transmission, they usually have more driveline power loss than the manuals.
Also, the cam can make a monumental difference. While the LS9 cam is fit for a blower, it is also an OEM camshaft which means that it does not have near the same specs as most aftermarket cams. The right cam with the right blower can make awesome numbers, like this build did.

If I said anything wrong, can one of the shops correct me? I am still trying to learn as much as I can.

Mine is an LS3...not L99.

I just think they are GREAT numbers!

Again, just curious...as to why the 100hp diff???

[Brian@Phastek]

We've made 647whp on a maggie with cam and heads and only 6.5psi cause that's all it would make with the cam and heads... So I'm inclined to believe this. They just have a person that knows about camshafts and an efficient blower.

What I put in bold in your statement is the most important part. Just cause it's the "ZR1" cam doesn't make it anything ideal for your engine, as your engine is not a ZR1 engine.

Iirc this is not the frist time RPM made over 700 rwhp on a stock bottom end 5th gen :-)

I believe the numbers. Well done guys. My car with Kenned bell and boostapump with futral cam did 703. The right cam will make a supercharger shine I made this power with boot cresting 9psi on the stock long block still holding up just fine. Enjoy the power man.

[94guy]

rjs, you were out of fuel though right?

[rjs]

was not out of fuel. fuel pressure was steady and holding. Not at all falling off. My point is yess it is doable. I am getting a dual fuel pump for the car though. Never expected the car to make the power it did.

[zr1gary]

rjs,
Mine was dropping at the 600 mark...using stock pump and the MSD box with the Whipple...but all cars are different.

yep thats my point all cars are different. And i dont for one trust the stop pump at that power level. Dual pumps are going in this month. Not going to find out how long the stock pump can last lol

I se no reason not to believe this it true, I built a Camaro about a yr ago that with Ported heads, Cam, 2" primary kooks headers, Kooks Exhaust, Twin pump, Magi with 3.1" pulley, Rotofab intake, and Snow Stage 3 boost cooler (water/meth), 18 deg timing, and 11.7 to 1 a/f, on pump gas. it put down 700 rwhp and 669 rwtq at just a hair under 10psi of boost. Here is the dyno chart.






Shortly after this dyno we put on a 2.9" pulley and it's making 11.5 psi, and has been running that way for a yr now. We never got back to the dyno befor my buddy moved to Autson with it, but I'm sure it's probably in the 720-730 rwhp range.



What I do find interesting is how different the Whipple makes power then the Magi, the Whipple made 30 more HP and 70 LESS ft/lb of TQ at basically the same boost.

Rpm installed a blower cam on my car and it made 58rwhp more....

A good blower specific cam can make a big difference in hp....

Rpm installed everything on my car and are a first class high performance shop....

I will put them up against anybody.....
