Dave, unfortunetely I can't dyno with the e-tops. The dyno is not set up for wet exhaust.I think the sport tubes have a 2" primary. If that is the case, you should not have any problems up to 800 or more hp before those headers are a restriction.

[WOW nice pice!! Is the oiling system around the valve cover rail for valvetrain cooling??

Thanks Charlie, yes the lines are for valvespring oilers. There are eight little brass tubes in the inside of the valve cover rail that spray oil on each valvespring.

Thanks Eddie,
I just went out and measured them and they are 1.875 just like the E-Tops
I will be dyno testing these motors wet and fully dressed so we'll see around March.
Thanks Again,
Dave

I know of one builder who just made 1360hp @ 12.5psi of boost, 93 octane, pump gas, 604ci, no methanol, expecting 1450 with methanol injection. Whipples made 200+ hp more than 1471 with 2.5 less psi. Thats by far the most I've seen for a performance engine. Requires big chief style heads.

Whipple Charged

1200 is certainly not the limit, thats just with traditional combinations. Just putting better SC's on your engines would net you well over the 1200 mark, but with your methanol injection, sounds like you got plenty!

Eddie,

Nice job as always, motors look amazing! Really like the way you mounted everything in the back.

Thanks Dustin. I actually made it to 1326 hp at 6600 rpm on 93 octane.(no methanol) EGT's had stabalized and actually started coming down. AFR's were dropping the whole time(stayed in the 11's) and it never so much as touched the knock sensor. Unfortunately, the dyno could not hold it for more than a few seconds. The water in the brake was over 160 deg. and climbing fast and it was starting to cavitate. I would have liked to seen where the intake air temps were going to go. Bear in mind that this is with 23 deg heads and a hydraulic roller. The customer wants reliability and a maintenance free valvetrain that will go over 100 hrs., not maximum hp. With more cam, more rpm and more head, who knows where it could go.

I got 830+ hp out of my 622ci N/A with 91 octane and cmi big tubes, and single 1150 carb. but I would love to find a 1471 to put on it. It's no match for some of the motors listed, but for a na it runs pretty good.

Eddie, nice work, and the pics are great. I have a question, not to change the subject, but how well do the valve covers work. I was told they leak for some people, ever have any complaints?

Next question, what Hydraulic roller cam did you take to 6600rpm?

Thanks!

Hi Dick the valve covers work great thats what i have on my motor.Some of them did leak but i hear they got that fixed.How is the back ,you ready for some out drives yet?

Mr Gadgets

Hi Dennis,
Thanks for the info on the valve covers! I am looking at them, when I get to that part, if money is available, I may just use them. I already have spring oilers in my rocker arms, so I shouldnt need that option.
My back is coming along. I am accetping drives, but only fiddling with them. Not really tearing into them. The operation fixed the problem, just have to let it heal! So, all is good with it. Tired of not being able to get done, what needs to be done, but I am patient!! Attemtping to get my motor to the machine shop for block work, that is the next step in that process..
So you dont need any drive work do you?? You shouldnt at this point.. !

I am watching this thread closely!! My hope is to get somewhere near the 1200hp they are talking here! Then see if I can build a drive that might live behind it for an acceptable amount of time. But that will be a big task.
Eddie, I took a look at your Skater 399 thread and I see cam specs are top secrect!! I'll have to do the best I can at guessing then.. LOL!
Thanks!
Dick
