287.6 BHP and 281 ft lbs woo hoo

[gmw9666]

Well a few personal bits n bobs yesterday meaning I didn't get on the rolling road until today at Shropshire Automotive Services

Great weather, arrived at midday



Then it was time to strap the old girl down and see if we've got any issues



Mid range issues highlighted and after some digging and root cause analysis the injectors were identified as potential issues so time for a clean which means off with the plenum




Let the cleaning commence




Omg how much crud came out of these




Screw the lot back together cleaning and replacing any needy parts



Ok let's see what see'll do after all the tweaks :-)

Ear defenders needed to watch this!!!!!



And what did we get, 287.6 BHP at 5794 RPM with 281.3 ft lb at 4811 RPM.........very pleased with that and the drive home tonight was a real hoot

She pulls like a proper monster

Great...Sounds awesome...Keith was the closest with the figures...Good power there..Theres only one thing missing...The pops and bang on de-acceleration..Enjoy the new beast...Ziga

[KKson]

As Mark says - awesome. Looking forward to hearing it in the flesh next Saturday. Cheers.

I knew she had it in her. That inlet manifold looks standard 38mm too. More to come there me thinks.

[mrzigazaga]

Actually thats very good power...What was the spec of the engine..Big valves?...Ported/Flowed heads?...Out of interest what do the 450SE push out..270-280bhp?..Thats a healthy amount of torque as well...Its impressive.....Ziga

[gmw9666]

Hugely impressed with the work MA did with Mike at SAS today

@wyn, indeed it is standard, so potential there if I needed / wanted

To say she did 293bhp back in 1993 after the rebuild dropping just a few ponies is not bad at all

The set up and throttle response now is savage it really is

@mark, may not have popped or banged in that video but on the road its like a gattling gun lol

All in all money well spent to fix the known issues that came with the car

One happy chappy :-)

Not bad... my 390 made 280lb. ft. but a paltry 256bhp at one of the Wedgefests... tuned by the seat of my arse

These are some serious numbers nice one The 500 Gredge is doing 297 with 312 Ftlbs with a kent 216 cam and red top injectors.... just wondering which cam you went for?

Hi Mark if I remember correctly when Wyn put his black 450se on the rollers at the wedge fest it made around 283 bhp not sure how much torque it produced or what the spec of Wyns black beast was ? But I'd say Glens 4.5 is bang on the money regarding what its capable of producing !! Both Glen's & Chris's motors are some of the very best wedges out there IMHO and both cars prove if there is a need for more horses put in the biggest V8 you can lay your hands on !

P.S It would be great to get both cars in head to head guys if Zig can organise another visit to the strip at next years BBWF

Great result Glen. Looks like the trumpets are shortened, or is it an illusion? With BV heads and 4.5l you should definitely get some benefit from 45mm trumpets and a blended inlet manifold. You don't say whether the throttle body is standard (65mm IIRC) but if not, that also worth doing - typically go up to a 73mm throttle disc. All it takes is money!!

Good eyes, those trumpets are indeed shortened and another good spot on the throttle. It's the full fat NCK bored out version :-)

Good result there, i'll bet that goes like stink now.

Nice one Glen. Hope to put mine on the rollers at Neil's at the w/e I'll be well chuffed if I get any where near that!

See you Saturday Ade, will come and cheer you on :-)

[Mr WST]

287bhp bet your well pleased with that. Anything near / above the 300 mark, got to feel good in the wedge.

Now wondering what mine could produce

Fantastic result Glen, that is only 13BHP off my Griff 500, I bet she flies!!! Mark Adams is a guru when it comes to getting the best out of these cars.

Stunning wedge she looks and sounds great.
