20% power train loss? a bit much isn't it? even in an auto, the stock numbers show a 16% loss, yes the blower will sap some too but that would be accounted for prior to the drive train.

I just have a continually hard time buying (from a engineering stand point - which I'm not a engineer) the the same components take 65 HP to turn, take 127 hp to turn when the power is upped. The rwhp is up 78% but the drivetrain takes 127 hp a increase of 95%.


Its not a standard number by any means, the best it can be is an educated guess unless you have an engine dyno or transmission dyno. An independent company tested engines and there number was 13 to 14% on average. SRA cars also lose less thru the drivetrain as well.

Its also interesting that the peak torque numbers are so low as has been mentioned with a KB PD blower, these cars are geared the way they are for a reason and heck in most applications they will need more gear.

When you get down to it its a 19% on my car, but 20% is the average for the 3 5.0's Ive based. So I used the average loss. I guess I could just add all the .7's and .9's to the numbers as well. These cars do produce less torque, but you wouldnt know it driving one. This is a new car platform, and Ive been very carful about the tuning. I could throw timing at the car and the tq would definitley jump up some, just look at the older 4v Cobras. Its just the design of the engine. The 4v head has always liked more timing than the 2v/3v heads .
Moving the cams around increased both tq and hp, so low torque isnt a blower or cam thing. At this point Ive only played with advance and retard. Today Ill spend some more time on the overlap areas of the cams. This ist gonna happen overnight, but the best thing here... I help educate you guys and explain things. I just wont say here you go, this is what you get.
More updates soon. Thanks Adam

Adam,
thanks for sharing. I will interested to see how things progress.

why is the torque so low compared to hp?

HP equals torque times rpm divided by 5252. Above 5252 as long as torque is fairly constant horsepower keeps climbing with rpm. High revs of this motor look to really make some nice numbers.

How did you measure the drivetrain losses? I think the surface is just being scratched and that with the right tune you may be right about the 12 psi safely. But it will require some significant TiVCT tweaking to alter the DCR.

Just leaving Kenne Bell with the new 168 mm t-body. Gonna try it out on the rollers first thing in the morning. Ill get a picture up in a few of the t-body, as well as the car. I plan on stepping the boost up some more as well. The plan is to touch 650 rwhp for this weekends event. Thanks Adam

Anxious to see the limit of this motor in stock (rotating assy) form. And so far all the numbers here sound right about where they should be as opposed to numbers other guys have posted with other power adders that just don't add up (psi vs rwh).

Plus 1 for you, am I the only one that saw the discrepancies?

Im all about accurate data. Ill will doing my best to keep people in the loop with the progress of the car. There will always be before and after dyno for each mod. I have a car on the rollers now. Once its done, Ill be doing the final cam testing and the 168mm t-body test. Ill post up the results in the morning. Thanks Adam

All we want as customers, whether past current or future, is honesty, accuracy, and communication. Sometimes shops think we won't notice when they make shit up, or hide the truth. We're smarter than they think, and in the end, it only hurts them.

Thank you Adam for providing us with factual Data and 19Cobra93 you are absolutely correct.

just wait for 302 to come in here and warn you that the stock 5.0 doesnt have a forged bottom end and its going to implode at 700whp. ROFL.

great work guys, cant wait to see it with more power. do you plan on doing a full exhaust?

I'am leaning this way also
I like the 2.8 LC but want a different TB (stock round is ugly)

I hope 2 run a 2.8L LC at 10 psi on 93 octane and meth (want 575-625rwhp with auto)

Wow!!! and to think I said I would never supercharge my 2011 5.0 lol

I've heard nothing but good things about Adam and ST and I will follow the developments on this R&D.

Adam will you be testing the centri blowers also ? as I'm also considering Vortech,Procharger,Paxton

If I decide to go with a SC I will keep the boost low 7-9lbs and since we only have 91 here in Cali well that would be the oct/tune I would use.

Thanks for keeping us in the loop and I'll have to visit your shop soon :)
