280ZX dyno session

[Mr.F]

Not something you see everyday - a 280ZX on a rolling road. This session done recently at Thurston Engineering's dyno facility with Peter in charge. Having scared him with a 500bhp run with a Z32 last week, this was a little more docile!

This coupe has a six branch exhaust and a larger throttle body. Produced 153 bhp at the flywheel but with a diagnosed ignition advance problem (too much too soon) and a rich mixture. Owner Digger Broderick has gone away to rebuild the distributor and investigate the cold start enrichment mechanisms...

Is that a manual?

Hoping to dyno mine at the end of the month, although it's an auto (currently)

 

[Mr.F]

Yes - manual gearbox.

Just inquiring
Is that definitely rwhp Mike as the dyno sheet says "corrected"
Plus 153 rwhp is around 190 flywheel which you would only see with some compression and a cam

Yes I know some dyno operators dont like flywheel as its "a guess" but the dyno at Thurston does have the facility

Corrected my post - having a blonde moment of wishful thinking...yes, flywheel horsepower as anyone who has tuned a stock injection 280ZX would have realised...

153bhp. Not bad for an early 280 motor with problems. Still 13 brake up on standard!

 

[SKiddell]

Very good result, must pull nicely

What year is the car - was it 140 to start with or more ?

 

[racer]

Early car as all our 2 seaters were, but with late bumpers. Early cars had 140bhp, 147bhp for the facelifts.

 

[SeanDezart]

Deeeeeerrrrrr !

Another blonde moment - only looked at the rear and saw what I thought were 2+2 seats.......!

Thanks mate !

 

[Mr.F]

Seats are US spec leathers with 2+2 style headrests.
I forgive you your sins...

 

[SeanDezart]

Thankyou father.....but I don't feel totally absolved - I should have noticed the space between seat top and head-rest.................I'll go and light a candle.
