Went down to Santa pod yesterday in the SAPH and parked her up on the north London / herts group stand, had a wicked day etc etc

i've never been worried about bhp numbers but just to the side of me was the dyno dynamics rolling road so I thought fuck it I ll see what she's made of....

There was a stage one SAPH on before me which made 264 which was about right, I pulled mine up and they strapped her down for the 4 runs....

I was completly shocked at what the outcome was 437.5 with 419 lbs/ ft !!!

Spec is

Standard bottom end / head ( 58k )
greys
t34.48
group a pump
500 cooler
4x4 inlet with 14mm spacer
holding 30psi to the limiter
a1 rallysport l6 chip

I will post the graph up later

what are your thoughts ???

 

easy, the rollers are not calibrated properly, or maybe the dyno guys inflated the figures to make a load of happy customers

 

I thought a T34 couldn't pump more than 380 ish??

Cracking figure if its true mate!

 

A brilliant, if not suprising figure

 

Absolute load of bollocks .

 

After I had got past the shock I mentioned the calibration issue had he repled with a 10 minute lecture about dyno dynamics rollers etc

 

Did you tell him that you have a turbo that physically can't flow that much air, so as good as the DD rollers are, they can't make your turbo defy the laws of physics .

What power was it at the wheels?

 

That was at the wheels mike does sound to good to be true mate as long as it feels good on the road i wouldnt worry dont get caught up in the numbers thing

 

Yes I did tell him that ain't he but he was quite offended when I told him his rollers where out. It was ( apparantly ) around 360 or sumit at the wheels I can't remember, I'm at work at the moment but will post the graph when I get home

 

on t34/0.48 never

 

Will be interesting to see what mode it is in . I blame operator error, as the DDs are usually a LOT close to the real world than that .

 

Carlo Im not intrested in numbers jus thought it would cause a stir on here and see what people say, If I thought it was a true Reading I wouldn't have argued it with the operater

 

Be good if it was true

 

Get it on the rollers when you see him at the next show as you'll have the T38 on it by then!

Should get 550 big ones piece of piss!!

 

Fucking right it would, thing us I've got a 38 to go on I should have fitted that them I could have seen the magic 500

 

Beat ya!!

 

You don't need a T38, you've already got the power one of them will produce .

 

 

It's weird how the car before you made the right sorta power.
And my m8 ran his Capri and they said it made 748bhp but last time he had it on a set of dd rollers it made 770bhp, so they read a bit less for him yesterday. But he said he had a slight miss when goin up the 1/4, he thinks down to plug boots. Not bad tho, he ran 11.2 on 888s with the miss.

 

Fucking right it would, thing us I've got a 38 to go on I should have fitted that them I could have seen the magic 500

 

I told you them tanks were good for a hundred brake

 

graphs now added

 

if you cause more drag by touching the brakes or something like that when the wheels are slowing down it will give you a bigger bhp result because thats when its trying to work out the transmission losses

phone up and say you want your fooking Ł45 back

 

Thats some figure.Does your car really pull well and does it feel that powerfull.

 

Sell your car while its big power on ebay make some cash to start again with a T3 600 BHP as fast as rods

 

It does feel strong but it aint a 400+ car, Fact

im pissed off because ive wasted 45quid

 

FPMSL I cant belive the people on the rolling road was trying to blag your head to say your car had that much power.

 

I hope mine makes that on my TT T38 when i get it on a rolling road

Steve

 

When is that then Steve?

 

Never seen a t34 make 400bhp....

normally the max is 380 and thats screaming the aasss out of it...

 

Think Ray still managed to take fastest rwd ford though didnt he? Noticed it wasnt as quick as normal as it usually runs 10.5 at 140 every time iv seen it.awesome car mind and a genuine road car.

 

Ł45 is that the going rate?!

 

Need to build the bank balance back up, done almost 4k on it

Steve

 

mine did and just as much torque


turbo was changed/rebuilt every 12-18months tho

 

lol....

Fair enough - mine made foook all near 400 on a rr but made a magic 405 on the dyno

My t4 makes good power though

 

Only 405 ding-a-ling. tut tut

 

He's obviously not an accredited DD operator, you can see that by the graph.... .

I'll let Christian explain .

 

dont wave the carrott and take it away ...........................

 

I've just had a quick look at the graphs and as much as I'd LOVE to pick holes in it, it doesn't appear to be far out in terms of procedures. OK, so they used Shoot_4F, not what we would do. But strictly speaking its the correct mode. We tend to use Shoot_4, which is for N/A but gives a slower ramp rate and a more realistic boost curve. They used 4th gear, which again isn't quite right, it wouldn't make that much difference.

I can only suggest it lost traction. The fact that the peak in power is almost precisely where it comes onto hard torque, I reckon thats what happened. The power drops after that, which is a shite power curve really. It's not too hard to imagine where the power would have been, had the torque not ramped to 420lb/ft, but to a more believeable 360lb/ft.

Oddly, they measured the Intake Temp at 4° colder than the Ambient Temp. Not quite sure how they did that?!!? In any case, that would have caused a negative compensation.

 

weird
sue them for false info lol
