I saw this on Endyn's site, figure some of you would like this stuff. Its a simple 2 liter motor with a stock S2 intake manifold, stock ITR throttle body, 440cc injectors, and a worked-over DC Sport JDM header and JUN 3 cams.

This was on their break-in pass with safe tune ...

I can;t imagine this thing with his cams, Hytech header and custom Skunk2 manifold ...

seems like good power. 262 at the crank is aprox 228whp??

 

That's only 210whp greg...

 

yeah i was gonna say... thats flywheel hp, not bhp.

still good numbers, but not what i thought i was about to see.

20% Driveline loss from an engine dyno...to a dynojet.

That's pretty weaksauce if yu ask me...I did 20whp better than that with an SMS Header and a lightly-ported skunk mani. Everything else is the same...maybe I should post my charts on larry's board.

bhp is flywheel horsepower....same thing.

 

I thought bhp was brake horsepower, which is different than Flywheel horsepower....

 

p.s. this thread is gonna get crapped on real soon and i think you all know why.

I was under the same impression?

 

BHP is Flywheel Horsepower...

I saw your first post I was just wanting a little further explanation if possible. Why the different terminology?

Thanks

EDIT: Figured it out. Google is my friend.

I find it interesting that so few people use seprate egt probes to use as a tuning aid. I always wanted to try that if i had the extra time. Seems like that would aid in tuning choices a great deal.

Good numbers but nothing outstanding.
Will be very much looking foward to seeing what is possible with better components and more aggressive tune.

Omniman's B20 is far more impressive IMO.

 

larry's NEVER done anythign that impressive

seems mostly like smoke and mirrors.....need i brin up the now infamous "290whp h22"???

 

That would be a good way to get this thread deleted.

 

gotta love that about H-T, huh?

Gee with all that stuff it will make alittle more than mine possibly... Thats pretty sad considering the guy who built it has like 50 years of building experience compared to mine who ws built by me. And to think, Larry says he can help me find all my missing power if i applied some of his theories..lol Mabye he should find his missing power first..
I bet the motor has already dynoed decent #'s and this post is a setup to see if people will comment and then the endyn camp can come back with some big #'s to try to regain some sort of respect...

 

Btw cheetah , your motors you have built are more impressive..

 

I think a lot of us will be surprised if he posts up the #'s with his cams and hytech header/different IM/TB. Did anyone look at the engine monitor #'s on the second page of his post?

 

I just read some more of that post. Headwork AND Jun 3's and all he got was 210whp?

 

I remember Chris at Hook Ups made that much with a stock block B-20 ,B-16 head type R throttle body, June 3s stock comp. And somebody made him A bad *** header with a muffler.Well kind of a muffler. 210 hp
untill he found out that the valves dont fit the reliefs

 

1) 210whp with headwork and stage 3's ? Leaves me wanting....

2) I too thought BHP was Brake Horsepower, which I KNOW refers to flywheel HP (from reading MANY R&T type mags...lol)... but why the hell is it termed 'Brake' ?

 

268 at flywheel is approximately 248 at the wheels. Whether it's flywheel or brake hp is not that much of a difference only a couple hp..
Drivetrain loss IS NOT a percentage loss..It depends on the car and on mine for instance there's 20hp drivetrain loss..Whether I have 100 or 200whp that loss in the same .This is at peak hp..The drivetrain loss varies with rpms..
Here in Denmark we measure the drivetrain loss to recalculate what the horsepower is at the flywheel when we dyno

This is what I found.

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by Canadian Driver Magazine &raquo;</TD></TR><TR><TD CLASS="quote">There are many different ways of measuring the power of an engine. Brake horsepower is a common term and refers to the power measured at the crankshaft using a "prony" brake. A prony brake was a simple lever that was connected to the crankshaft with a brake. As the brake was applied, the lever would deflect and power was indicated. Nowadays, computers and strain gauges are used to measure the power.

Sure it is. It's just a variable and not a constant.
