What's the average BHP for a 1776 engine, does anyone know? Just a ball park figure for a stock engine!
I would reckon about 60-75, possibly more, depending on what cam, carbs, crank you've got? You still have the twin 34s?
all depends on the heads and cam really... exhaust and carbs will make a difference too full spec would help
Good point. I had my stock 1795cc tested a few weeks back. It recorded 61 bhp at the flywheel and 37 bhp at the wheels. 24 bhp was lost to the transmission!
i thought standard late type 4 2 litre was the highest "out of the box" at 70bhp so can't be much more than 60? on a 1700??
On the rolling road we got an estimated 80+ but couldn't give an exact reading as there was no rev counter but even not being flat out we got 80 so i guess that's good then. 8)
I think my 1800 type 4 is 70+ off the top of my head. That's stock apart from dell 40's. I did better than VW Yours sounds about right, slightly more than a wet fart but less than a ride on lawnmower. Are you sure your rolling road number is bhp and not speed? What output did you get, I don't understand how they could get any readings if they're not recording any rpm on their equipment?
No idea mate, he had things plugged in and got a print out of something. Let's put it this way, it pulls better than it ever did and sounds superb. He wrote BHP at estimated 5000rpm 80, up 19 from 61 when it started. 8)
The type 4 engines all had a similar power output Rick, the difference is in the torque curve, gearing etc. A 2 litre will be less laboured than a 1700 but won't be any quicker.
He had a machine that recorded stuff, he didn't max it out as the engine is only 600 miles oldish however the machine has lots of dials and stuff lol. ;D http://www.dnbaccounting.co.uk/dnbconsulting.co.uk/aireytuning.com/services.htm
Tezzah man so you'd recomend a trip up to see this bloke? being at Petersfield he wouldnt be far from me. did he do all the work jetting of carbs etc just that I remember an old post saying he was getting on a bit and you would have to do the crawling round for yourself. keen to get on a RR and see if my bus can be improved.

He was alright to be honest despite my reservations, i took the carbs out (he's flipping 77 and looks 50 but has trouble bending now lol) and he took them and rejetted and all that. There was a massive difference, just google the guy, he's used by a lot of classic owners.
He will explain everything to you and has all the tools you'll ever need and row upon row of old carbs and plugs, a real treasure trove. 8)
