How Much HP??
 

I am looking for some HP guestimates, estimates of what it should be making. I have a 540ci Chev 9:1, Dart Pro1 Heads, Gil Exhaust, Whipple 3.3 Intercooled 10lbs Boost, Full MSD, Topped by a Dominator 1050. I am still tracking down the cam specs. What range of power should that combination produce.

Looking for any and all input.

Thanks

get the cam info and some educated guesses can be made, but until you dyno it no power bragging is allowed. :D

Re: How Much HP??
 

540CID x 1.1HP/CID x 10boost/18 =900HP
Thats with good heads and optimized cam.

Re: How Much HP??
 

OK I have the cam specs.

549 lift int and exh.
duration 230 and 236 @.050
sep 112

My main question is the fact that the builder dynoed them at 675HP at 5600. Seems a little (lot) low. Any ideas??

Re: How Much HP??
 

The cam is killing it, flat tappet I presume?.....probably could use more carb also....

Motor should be making 950hp easy @6200ish

Whipple claims 740hp dropping the 2.3L on a 500efi....

my 540 just dynoed at 944hp@ 5600/962ft lbs @ 4400 blowing thru a stock merc plenum and modified 502 mag intake and its a 8-1 motor w/10 lbs boost(procharged M-3). Are your heads out of the box stock or have you flowed them to see intake to exhaust ratio?2 years ago on dyno my 540 only made 629 hp/697 ft lbs tq at 8 psi,the merlin heads were killing it with there terrible intake to ex ratio,i learned alot about importance of flow #'s,especially ex flow from guys on this bd,your cam sounds identical to my old cam too (except your lift is .050 less),i went up to a 234/240 at RM BUILDERS recomendation this time,i think it helped too,Smitty

Thanks guys. I think I have a larger problem now. About 40 mins into the new motors, I had a rod poking out of the oil pan on the port motor.

Anyone have a pair of 540's sitting on the shelf?

That sucks!!!

Roller Cam. Lets put it this way. The Whipples on my stock HP 500's made more power.

What did your motor builder/dyno guy say when the motor puked?I can almost imagine too that when it made 675 hp you were told that was safe,reliable hp,am i close?
