My god! I am very concerned about this, what is the full title of the law and the bill number? As a solicitor I would be keen to read the full ramifications of this law and the insurance company and case if possible

So you don't work down the local car wash anymore then Ben?

Mmmmm, suits you sir. happy birthday LOL

Ben, you smell of bad cheese

I can't believe some of the s**t i read on the internet. Tight PTV my arse. Shock statements to make you go to them for the work. Its bollox.

Buying a decent wideband lambda logging facility might be a small part of the job too

If you have to go for a bike engine, don't use the R1. Its has about 70 ft lb torque. Hayabusa is around 105 ft lb stock or 140 lb ft at 1500cc. The R1 won't pull the skin off a rice pudding! I've got a lot of autograss customers using bike engines. They have spaceframe chassis weighing...

Yes, car too heavy for those motors. Hayabusa is the way to go if you do it. About 180bhp at gearbox output shaft with a decent exhaust, 240bhp with 1500cc conversion or up to 700bhp with turbo. Both last options will cost over £5k and that's before you've even fitted it in car. Oh and the...

No no no, he's trying to run michael jackson over chamone

Rumbled again!! You don't miss a trick. He told me i wouldn't feel a thing

Lol. Cant believe you found that picture of me. Also can't believe he let me sit on his lap

Yep. Thought driving my racebike around in a transit would have the same thrill ....... sadly i was wrong. Looking for a toy car to make up for the long hours now.

I did this mod to my 172 cup and it made a noticable gain without any further mods so doing the above mods as well should work out really nice for you. Awesome website Ben. Long time no speak. Looks like things are going well.

Ben, Check your email. I've sent you some thoughts on the flow figures and some of my pfa data.

I'd have one of these http://www.bath.ac.uk/~ccsshb/12cyl/ in my mini LOL

Has anyone here ever put one of these engines on an engine dyno and know what they really produce? Manufacturers always claim way more than vehicles really make. I recently built a 1400cc hayabusa engine for an autograss customer. He took it to a local dyno where it measured 140bhp at the...

A trip to Prague with the boys. Worth more than any car and you'll never forget it ;)

As stated below, its a time thing which means cost. All manufacturers leave engines like this. Very rarely they hand finish them but you pay for that when you buy the vehicle. Its not just the inlet manifolds that have discrepancies like this, you will find it throughout the car and engine if...

My opinion is it needs to be removed as swirl should be created later on by the entrance to the chamber. The last thing you want in a port is a dead area. There is a lot on mixed opinions on the subject of creating turbulence and port finishes. One of the most radical yet is this one...

I'll be very keen to see rpm levels and their reliability from anyone who goes this far. Still seriously contemplating racifying mine. Yes, the builder is the key.

Not trying to hijack this thread, but keep seeing posts on costs of TB's and it shocks me. How can throttle bodies cost 3.5-4k? I hope that comes with ecu, loom, fitting and setup? Just a thought, but why not use tb's from a bike. Example 46mm off a hayabusa, 45mm off an R1 etc probably cost...

Its is very simple to fit as long as you've got a half decent tool kit. Its about a dozen bolts and you have to remove a bunch of connectors and a couple of pipes.

Mostly i'm involved in circuit racing (superbikes and supersport). Do work for the autograss community as well. Don't get to any other meetings. My business is called Race Developments. Not familiar with roger uperton.

If you look closely at the picture i posted you can see the plenum marked up in blue as well. I did both but the worst and most important bit is the manifold to head join. If you want the plenum cut open and heavily modified as mentioned earlier then speak to BenR. I just haven't got time for...

Depends what you need. Drop me an email to tim@racedevelopments.co.uk or phone me on 01452 305343

That would be why the tuning potential is so limited then compared to stuff like the duratec.

How much bigger could you go on the valves before you get shrouding from the cylinder walls?

Don't forget the 2kg of BS i also have to carry onboard:D

Honda have the time and money to put reliability into performance. Their car engine technology is only 10 years behind motorcycle engines whereas all other manufacturers are 20 years behind.

You can just use a marker pen instead of engineers blue
