If you had the car on the Aldon Rolling Road which we all know is pretty damn accurate then you would see 20bhp less than that figure if not more.

Looks to me that that rolling road you used wasn't accurate.

I had the same spec as you a while back and got 150bhp at Aldon and i know of many others who have simliar specs which run 150-155bhp.

Post by: hardchargin40 on September 20, 2009, 10:25:04 am: Is that two runs shown on the graph? Or wheel and predicted flywheel power/torque? Seems pretty unrealistic, sorry dude.

(Torque X RPM) / 5252 = Horsepower

Id guess by the bottom torque curve that 150lb/ft * 5716rpm / 5250 = 163bhp.

Post by: chris2911 on September 20, 2009, 03:21:01 pm: think that rr is totally inacurate im running same spec and a big valve head and putting out 155bhp
i got mine done at the g40 rr day at aldon.

My engine had the same spec in the last owners car and had 157bhp at aldon!

Post by: hayesey on September 20, 2009, 07:53:35 pm: I've never seen a g40 with a spec like that make anywhere near that power. The standard head especially makes me think it's not possible. Unless there's something else you've done you're keeping secret ;D

Post by: grey G on September 20, 2009, 10:53:25 pm: The overlap shows before and after the custom manifold over a supersprint. I know the results seem high but having said this keeps level with a bmw e46 m3 and jaguar xkr to 130 mph. The torque is very consistant.

Post by: polo classic on September 21, 2009, 10:39:20 am: My car isn't even making that with ported head, custom cam and custom mapping.

I do not think your numbers can be reliable

Post by: grey G on September 21, 2009, 07:00:55 pm: Well nah nah nah nah nah! ::)
Joking aside I can see where you guys are coming from thats partly the reason we posted it, but saying all this JP race said the standard diff was the worst they had seen due to the torque, has also snapped driveshafts and kills cv joints. It does outrun audi s4's and lotus exige's to well over a ton. mk5 gti's are destroyed!ha ha. Will get it on another dyno just to see. This dyno was 2 years ago we just thought it would be good to post it up, cheers guys.

Post by: SamG40 on September 21, 2009, 08:36:15 pm: I always say that as long as it is quick enough in feel then any nice dyno figures are a bonus. I do agree with the rest for most part but didnt Michelle's now Pettsy's white machine make silly power for the mods done years ago? Although wasnt that at stealth?

Looks a nice car though, get some more pics up!

sam was that the white one?

Post by: SamG40 on September 21, 2009, 10:06:29 pm: Yeah it was white, running 15" ATS cups when she had it.

Post by: grey G on September 23, 2009, 07:05:13 pm: If for example the power was over reading does that mean the torque will be too? By the same amount?
Title: Re: 1272cc G-Lader Dyno Print Out
Post by: hardchargin40 on September 25, 2009, 07:29:28 am: Should be as power is a product of torque and rpm.

...unless the operator really messed something up inputting data before the run.

Do you know if he did a tranmission loss run down or just got the loss figures out of a book?

Post by: Yoof on September 25, 2009, 10:26:19 am: Power is torque x speed divided by 5252, so yes, they are related.

Only time you'll be able to differentiate between them is if you only apply a correction factor to one.

Correction factors are a calculation (If done to ISO standards) which rely on barometric pressure, relative humidity, air inlet temp and ambient air temp.

Your spec points towards the mid 150bhp area, which isn't to be sniffed at by any means :)
