GT 240 Options

I have a GT 240 built on Intercontinental cases, running Dellorto 30mm carb and BGM Clubman exhaust.
It’s a superb engine but I’m after a bit more power.
I’ve heard that an expansion chamber can really wake these up, can anyone recommend a pipe that’s not too peaky and not too noisy?

The recommended expansion is (I think) a Fran Race, which is what I use on my GT240. It does give a nice power band once you get over 5k rpm without taking too much away at lower revs.
I've never used a clubman so can't say how it compares, but I did have a borrowed JL3 on this kit initially which delivered a very flat power delivery, which I found boring & much prefer the Fran Race.
I notice Eden now lists a 64/110 crank for sale which I think would go straight in to your cases. A much more disruptive change of course, but thought I'd mention it as it could be something to consider on a future rebuild as that would deliver a few extra cc's & power.

Thanks George that new crank does look interesting.
How do you find the noise level on the Franspeed Race? Is it a similar level to the JL3?

It was a few years back so hard to remember but I think was around the same.

I've heard the Ron Moss ex-boss works really well with the GT240, the latest BGM clubman isn't great, in reducing the noise they have reduced the performance of the pipe by quite a large margin compared to earlier versions. Franspeed Race is the preferred expansion, I have one on my GT186 and that works great, another alternative is the CST7 which I know a few people use

I'm using the BGM clubman on the EVO engine and it goes like stink BUT it has had the internal baffles brutally operated on and it is louder.

I’ve been trying to track down a Franspeed Race, but looks like they are no longer made.
Has any one tried the Fran Supertourer or JL RST with a 240?
I’m not looking for a high revver just a bit more kick than the clubman.

Have you rang Andy Francis he may advise ? I run a 240 with the race pipe it’s the best one to get the best out of the kit IMHO

Just be aware of the VAT, import charges and courier fees on top of the prices advertised

Thanks for the link but SIP are out of stock too. Yes Andy Francis said they aren’t being made at this stage.
