What gear are they dyno test with? I would guess that could make a difference.

4th gear, as it's closest to a 1:1 ratio.

+1....Also, Nicholas used a Mustang Dyno for future reference....

Here's mine. Note that the car isn't quite right at the moment as I'm getting 4000+ HCs through a gas analyser. Should be down at 6-700ish with my spec.

Max BHP (flywheel): 160.0 @ 5800rpm
Max BHP (road): 126.5 @5800rpm
Max torque: 203lb/ft @2300rpm

Spec:
B28E engine(lifted from a 1984 UK Volvo 760)
UK stainless exhaust
Reprofiled cams (fast-road spec)

Will be putting it back on the dyno once I've sorted the HCs issue. Have checked pretty much everything bar a vacuum leak, so that's next to look at.

What brand of dyno did you use? Is the TQ measurement at the wheels or on an engine dyno? I'm curious how that engine has so much more torque....

Also for reference, doing it in an automatic was a bit difficult. We tried to do it in second gear but the shift from first to second started this oscillation in the dyno causing the car and the dyno to fight back and forth.

In the end, the test was done first gear with the shifter all the way back in first. (and since it was an early vin automatic, I had to disassemble the console to get the shifter into first)

Dont necessarily remember the torque but I remember it being crap.

Wow, gas analyzer. Your working with a high tech test group. I see your chart shows the test was done in third gear.

Vin 1768 on a Mustang dyno:

Max WHP: 114.1 @5300rpm
max TQ : 143.6 @2800rpm
57k miles
stock engine
empty cat
MSD 2 coil
cold air intake
2' more timing than stock


Comparing my previous best run on the dyno which was ran without air cleaner or cat vs the new coil, with air filter and cold air intake installed, i gained nearly 10hp and just about 13 ftlb of torque! This is the highest power iv ever heard from a stock engine

Not sure on the brand of the dyno - these are the guys who did it: http://www.lsv8power.co.uk/

They do a lot of work direct with the manufacturers (Aston Martin, Porsche etc) to make sure cars off the production line are putting out what they're supposed to, so whatever it is it's pretty well trusted!

Would everyone agree the drivetrain loss for a 5-speed Delorean is around 25%?

I was doing some math and that would put my engine close to 190HP at the flywheel with 141 HP at the wheels. If drivetrain loss is only 20% than at the flywheel it would only be 175-180HP.

Wow! That's not bad. Almost 6hp from the CAI alone. How much did it cost to have the exhaust ceramic coated, if you don't mind me asking?

Quote below taken from Stephen Wynne at DMCH recently on another thread...

"Many people got the chance to drive the Stage III at the track during the DMC Open House this past October, and it's now available for installation.

Performance numbers are an estimated 233hp and 230ft lbs of torque at the flywheel (based on the generally accepted 32% transmission/tire loss for horsepower and 20% loss of torque). Over three runs; one on a 90degree day and two the following morning with the temp in the mid-upper 70s, the max horsepower at the wheels was 157.53 and torque of 184.48. The low numbers on the 90 degree day were 153.97hp and 179.64 ft. lb."

I agree with the power loss DMCH quoted. Most stock engines (known 130bhp) dyno just under 100hp at the wheels. Josh I fiqure you at 185 to 190bhp. Nice numbers for a NA motor!

If you go buy what Stephen said for HP drivetrain loss (32%) then actually I would have 207HP (207HP-32%=140.76HP) and 175TQ with 20% drivetrain loss(175TQ-20%=140TQ)


If you do the math, 130HP-23%=100.1 HP which is what most cars chassis dyno.

Therefore at 23% I would have 183HP at the flywheel which sounds more realistic to me than 207HP.

Am I doing the math wrong?

Stephen said "max horsepower at the wheels was 157.53 and torque of 184.48" with the stage III supercharger. So my NA car is 16.5HP and 44.5TQ less...I would think there would be more HP out of a supercharger setup. It appears to have alot more low end pull.

Does anyone have stock torque specs on the chassis dyno? I believe 160TQ is stock at the flywheel?
