Well the new motor is finally going on the Dyno to break in and tune the Terminator Alky injection system for max (safe) power!!!

Should run it tonight or tommorow night.

Anyone care to guess???

Bottom end:

Indy max low deck Aluminum block. 540ci w/ 4.5 bore and 4.25" stroke. K-1 Crank, R&R 6.635" billet Alum rods w/ 2.20 rod journals.
Custom Ross domed 15:1 compression pistons w/ 1.205" comp height. Charlies Alum oil pan w/ milodon dual line swinging pick up and Melling HV pump.

Top end:

2100cfm Ron's Terminator Alcohol Injection on a low deck Indy manifold, 440-1 Alum heads 345cc intake volume CNC ported by MCH, 382 cfm @ .800"
Custom comp roller 286/288 dur @ .050", .782"/.765" lift, 111 lsa installed at 107 icl.

Headers: TTi 2" - 2 1/8" in chassis step headers, w/ evac hoses.

I am hoping for 850 HP

Any guesses or advice for the dyno session???

Cheers,

Arnie

You have more cam ,compression and flow than mine does,mine has two 1050's on gas and it just made 870hp on Dwayne Porters dyno. Mine was peaking at 7300-7500rpm. I use a vacuum pump instead of evac tubes. I bet it'll be close to mine 850-880hp once dialed in

I have a very similar combo, differnaces being tall deck, megablock at 528 inchs, made 847 hp . Good luck, hope you make more!
On advice, If I had it to do over I would have tested with more heat in the motor, as I wound up running it much warmer. Tested at 140 degrees, run it at 190.

Thanks guys,

No vacum pump could set me back a few HP.

Greg, I will start the pull around 160 temp by warming up on gas with my primer plus, then switch to alky for the pull. Based on your advice I will try starting at higher temp as well, although it will be tough to keep the motor warm once at the track...

Any other ideas for testing on the dyno??

thanks,

Arnie

I use a fair amount of fuel, but haven't had too much trouble getting it up to 185 before the burnout box. with your primer plus, I bet it will be very easy. Not to mention cheap. A guy can buy a lot of 92 octane for the price of a couple of gallons of alky.

I say 925-950hp

Thats almost identical setup I run. My combo featured a 4.5 stroke and 4.44 bore..Same heads, same compression, same induction..Same cam, bla bla bla.
I never dyno'd my engine, but I can speak of track times.
That engine went mid to upper 7's in the 1/4 mile, 144 mph in the 8th mile in the heat with a 1.06-1.07 in the short times in a 2100 lbs car.
IMO the extra stroke I have on you isnt worth much if any at all....Matter of fact I think you have a better combo....maybe...track times is what counts...we dont race dyno's LOL..

Nice combo

on my 636 i've got dual 2100 terminators and the primer plus system. it warms up to 170-180 very quickly but once i switch over to the alchy it drops to 120 pretty quick! And using the primer plus with gas makes plug reading a lot harder.

Only advise is know a lot about alchy before going to the dyno. Whe i was there i wish i had someone that REALLY knew what they were doing.

875-900hp

Thanks for the input guys,

I went only 4.25" stroke in order to run a few more rpm's before the 440-1 heads peaked out... that allows more rear gear and torque multiplication.

Also since it only has 10.5W -31 slicks and 32" ladder bars, i did not want to much low end torque. Alky makes good torque anyways right?

Somewhere between 850 and 875 HP would be great but like said , we don't race dynos!

I really just wanted to get the baseline tune from the dyno very close and then eliminate guesses next spring.

Cheers,

Arnie

With a 4.25 stroke, torque will probably peak at 5,000 maybe even less. Mine came in at 5100 or lower. Peak hp at 6900 and 7000.

Here was my tune for 0 1/2 Rons pump...
38 nozzles, and a 86-90 bypass pill.

Thanks Greg,

It should like a shift point of around 7,200 rpm then. Right?

Bob, that is exactly where i am starting the tune! o - 1/2 black pump, 38 nzs, and 87 pill to start...

Thanks for the input.

Arnie

845 hp 6750 rpm torque peak around 5300 RPM, hope the session goes well for you

Well we made a couple of pulls on the 540 and it made 859HP at 6,800rpm and 726ft-ib at 5,500rpm.

Problem was there was a lot of blowby, enough to pop the breather out of the valve cover and paint the wall with fresh oil...

Switched over to a gas carb and it made 820HP, but with no blowby.

There was no evac lines on the dyno headers, so it was just straight breathers, so they have now installed some evac check valves in the adapters from the headers to the dyno room exhaust and while running a different motor they measured 5 - 6 inches vacuum.

We will try it again to see if that helps reduce the blowby and maybe even pick up a few more HP

Also the tune-up was using 37 nozzles and a 96 (large) bypass pill, so we are going to try a set of 36 nozzles and a smaller bypass which should provide more pressure and better atomization of the fuel which can also reduce blowby.

I know a vacuum pump would help even more, but i would like to try and run it with just my header evac tubes this season, and if it hooks and books, i can always add a pump for 2011...

Any ideas if the evac and smaller nozzles will help???

Cheers,

Arnie

Not sure what it would have blow-by with with alky and not the gas? But the power difference is substantial. Makes me wonder why I bother with gas. Nice numbers!

Those Indy's are making more power then our B1 orig. Great motor.

on gas my engine did not like a over rich mix and would blow the breathers off so i would say lean it a bit on alky.too much timing did this also.

FWIW, my motor made more power with hot oil and cool water temps.

Both around 145 or so. Oil temps under 130 really showed a drop in power.

i just came off the dyno last week with the owner of island dragways motor it made 920 on gas at 7300 but it was still going we run it with a terminator we use a 1 pump 40 nozzles 86 bypass 86 in the high speed the heads are 365 indys we use a star vacuum pump
