304.1bhp and 330 lb ft

Just thought I would post this up as I was pretty pleased with the results at a rolling road day at 'Surrey Rolling Road'
This is a standard 5Ltr.

Wow well done, that is very good.

[JamesK]

If that's accurate and a standard engine that's truly exceptional. Do you know 100% it's standard?

The beards seem to accept that 280bhp is a very healthy 500 and not many make even that.

[SILICONE KID]

Mine made 339bhp after the thermal insulator and a bit more tuning..

I thought yours was far from standard Daz, what with megasquirt etc ?

OP, very good figures ! how long have you had the car ?

[BeastMaster]

My 94 500 made 238bhp at the wheels a few years ago - was told at the time it was about right. Not sure how to get to flywheel figure or how much difference between dyno's.

Thats what my mildly modified 450 made a couple of years back. I believe it was 278 at the fly

Had the car about 30 months, been through the vast amount of paper work/history and it was very well looked after. Regular service and maintaned 'regardless of cost' One invoice was to have an indicater bulb changed £55 But there is nothing there to indicate or suggest any engine work or upgrades.
Charlie at Surrey Rolling Road said to expect between 250 and 280 bhp and after the run said that he had only seen one or two standard cars previously with that sort of BHP.

Nice one Barrie, remember chasing you around the roads on one of Tony's runs and it's a superb car.

Offer of blat in the Cerbera still stands, go on, you know you're tempted

[haircutmike]

That does seem like an exeptional figure!

At Roar 08 on the Saturday, the highest scoring 500 was about 270 bhp on the Crazy Horses rig.

I knoe Barrie ran 109.4 mph terminal over the 1/4 so the performance is there to back up the bhp IMO.

I am not sure about that crazyhorse rig at Roar. I 'only' got 332 bhp on there in 09 and ran 11.8 @ 120 the next day at Shakey.
Power was down about 25bhp NA compared to a dynojet i had been on.

I should imagine SRR is consistant.

Alexdaredevilz alledged 4lt ran about 250 a couple of monthes ago which I thought may be over reading but imagine my disappointment when my 4.6 only turned 271 and 304 torques

By that token the OP's figures are bleddy great!

My car is now banished to the garage with it's top end stripped, packaged and ready to go to V8D so we can find some more ponies!

[Vixpy1]

Best standard 5L I've ever seen, by far

Hasn't he just posted engine number indicating its actually a V8D 4.6? In which case 250 would be a pretty weak result indicating some fundamental problem.

[SILICONE KID]

I`ve had the car about 3 1/2 years.Its been on the rollers since this read out..now 339bhp

Yeh I agree spend.

It seems to have had some port work done by previous pics but may have standard valves and a tame/standard cam.

Could also be as simple as timing retarded a couple of degrees?

Really wow, that's the first I've heard of it, well done.....

Do you have a graph you could post up?.... I'd love to see the power curve...... If it included before 14cux and after even better.....

I bet his cats breath smells of cat food
I wonder which TVR owner simpsons character i would be. Otto maybe
Maybe a new thread

Good idea Quinny, Daz when you post your graph can you add the words MARK & ADAMS too please

Oh and some MPG figures would be nice.

[SILICONE KID]

Who is Mark Adams ?,never heard of him.I will scan the new graph for you..It could be a bit weaker in areas but the tuner likes to keep it a bit rich to be on the safe side..Does it look a bit rich..I got 28mpg on a run 70mph 31mpg about 60mph ,knocking around and the odd blast 22mpg and driving like a nutter about 14mpg . wonder what i will be getting on the track,got my silences so im ready to rumble..The only place i know its rich is on idle in the 12`s..
