Had the car on the dyno yesterday - now at 16K miles, 3k miles past rebuild to 'latest' std spec. The dyno I use is trusted to be very accurate, but the figures were quite a bit down on what TVR claim for the 4.0 SP6 (surprise surprise)

330bhp @ 6800
280lb/ft @ 5300

anyone else got any comparitive figures for their SP 6 engined car?

cheers

that's very down on power.

all the sp6 cars I've tested have been bang on the money, one car (the ex jon lewis bollox car) made 373bhp from a std engine (well it being a ex dealer demo car we were wondering if it was in fact red rose spec, though there was no documentation or marker pen to support this) ..

your car is losing hp somewhere though if your dyno is somewhere near the mark ..

Shirley it depends on the dyno? from what I've read they vary quite a lot

the dyno in question is within 10bhp of another 2 dynos Ive used on my Elise. They also have an engine dyno, and the RR dyno gives similar results for a given engine on the bench and the road. I dont doubt the accuracy - I could understand it being say 10bhp out...but not 30-40bhp

May take it elsewhere for another 'opinion'

Problem is they have the software to map the ECU, but apparently its locked by TVR so they cant see whats going on/adjust the map in anyway?

yup, hence austec investing a lot of time and effort into getting some software written especially for them.

My local rolling road build teh engines for Noble, they're remapping MBE ecus all day long, but they had nothing to ulock the tvr version .. you're stuck unlees you goto austec or substitute another ecu.

Yep 330 bhp seems a little low, however your Engine has only done 3k since it`s rebuild and these engines feel more powerful as the miles increase, IMO, whether it will gain it`s lost 40bhp (2003 spec)is questionable? 330bhp is still more than MOST RV8`s AJP`s though

yup, but the midrange is some 70lbs torque down on a good ajp8

how close are you to chesterfield? fancy a run at Nobles for comparison to all the other tvrs that go there?

I hear what your saying about the Torque figure, TVR only claim 310lb/ft as you know so it`s not going to compete on torque is it normal for torque and power outputs to lose the same amount? It`s about time WE Tuscan owners got together to have a dyno session, I can feel a meet coming together after ive finished the TUSCANEERS weekend
Not sure how many voluneers we`ll get after all the "stories" on here mind

The yorkshire lot are looking to organise a rolling road day and are talking about Nobles as a possibility. If it's the one you use they must know what they're doing.

The 4.0L SP6 is well into the 300's in terms of torque - so yours is quite down

i thin on a one-off basis it's 50 notes .. probably less for a group booking basis.

I take it they're not open at 8 in the evening?

£50 isn't too bad... must get something arranged while the air's still nice & cold & dense.

finish at 5-30 i'm afraid.
doesn't matter about the air being dense .. their booth has a chnge of air every 10 seconds or so and can maintain 4degC in summer.

I had my Red Rose on a rolling Road last year, but as it was for a photo opportunity for the German software company who had just updated the rollers software, they did not fully strap it down so it made 330 bhp at 6382 RPM before it was wheelspinning with smoke pissing off the tyres. They said the power curve was still going straight up(as a curve can) so it had a fair bit more in it.

I have not got around to going back there, also I would prefer a Rolling Road that has been used before for comparison, maybe Austec or that one over west country way that was used a few years ago for all the cerberas and one Red Rose tuscan turned up and spanked them all.

cheers
