well got it in at last at SCA i got, 193.6bhp, and 256lbs of torque, was hoping for over 200bhp, couldnt keep it down though, keep wheelspinning off the rollers

might try somewhere else now

quite pleased though, the graph had a nice smooth curve thanks to the mapping by Gary@apt

what do you boys think, i think i should of have over 200bhp, but the torque was good!

 

If gary mapped it, why u roll it @ sca?

 

cus apt dont have rollers? and sca are the only accrute ones nearby perhaps?!

 

That is why!!

Unfortunately, we dont have a spare Ł50k lying around at the moment!!

Anyway, Nathan, you have Email.......

 

to me then

 

thought it would have been more my mate had his turbo corsa on there an that had problems staying on rollers that only made 190bhp went to that rolling road day at auto point it done 240bhp so must have somthing to do with not keeping it down...

 

I have explained to Nathan, that his car definately has a harsh Boost Spike, which is causing it to break traction. The result of this is an inflated Torque reading.

RS Turbo's are always tricky to RR, because they have brutal Power Delivery, which is what causes them to lose traction and also break Gearboxes, so any RR Operator will struggle.

Having looked at the graph and knowing the spec of the car, I would easily say that it is beyond 210bhp and would estimate that 240-250lb/ft is a more realistic indication of the Torque.

A Standard Head is a good way of maintaining the strong feel to a mid-powered RST, but by porting the head you smooth the peaky Torque curve out and it will feel a nicer car for it. This helps it to produce more Torque higher up the rev range, but probably less Torque in terms of a Peak. The other symptom of this is that Gearboxes will last longer!

Hope this helps.

 

Good result there mate

And top explaination by Mr C

 

thought it was a bit weird not being over 200bhp well at least thats explained

 

yeah well done christian, thanks for your help mate, pity autopoint is shut, anybody used Henstead's rollers?.

Another thing been booting it around allday, and the clutch is slipping!, think i need a paddle clutch now!, oh well lasted 2 months!.

 

dont go to hensted heard lots bad things there rollers are way out too try courtneys they now have auto points old rollers and they will do any car not just vauxhall's

 

cheers jon, will give them a try

 

looks like i better get me arse in gear with the car then eh! ..lol.!

 

AWESOME torque figure!! I'd be over the moon with that mate!! Rather have a high torque figuer than bhp to be honest

 

had mine set up at interpro today!! 223 bhp 246 ib/ft torque at just 14 psi
