but that is more cash !


Ouch! Guy Croft was very complimentry of the Longmans/Jenvey inlet manifold. When he flow tested the head with and without it he noticed a marked increase in flow. He went on to say this is very rare as most bench tests he conducts with a bare head flow better than ones with an inlet fitted. (Obviously he radiused the port with some plasticine for his tests, not just a square edge) Is there some hard data to prove that Colin Satchell's inlet is actually better? I don't doubt you for a minute, I just can't see it bieng hugely different as they both have to have a similar bend radius in them for the bodies to fit under the bonnet.

it might on its own flow quite well and I don't doubt Guy's figures one bit

but this is not about flow directly at all, its about the pulse tuning regarding the cam timing, throttle body port diameter, trumpet length etc.

the point regarding the off the shelf manifold, yes the initial radius may be the same as Colins design, but that doesn't mean the bodies will be at the right angle to get a decent length tract if the inlet is too short, you'd need a sharper radius with that length manifold to achieve a decent length overall.

surely a fabricator of your skills could knock something up though?

obviously this is purely based on observations and experience of other peoples work, not my own, I wish it was! and also a brief chat with Colin about them.

as for the hard data, I don't know if there are any direct comparisons on an XU, only that Sandy and Colin's approach gives quite a lot more usable torque bands, I think Sandy has a comparison an a TU engine build from Jenvey to sandy/colin inlet.

I would ask Sandy if there he has any hard figures he'd be willing to part with, as ever its about looking at the whole package rather than a single item or pair of items in isolation.

im sure all will be sorted at usc this year. i was told that matt jobling designs and profiles his own cams which could be what the differnce is. but it all comes down to driver tyres etc. nicks car is dyno proven 264bhp i belive

BTCC regs meant standard lift only, but duration was unlimited.

was on 48s m8 but 11mm lift cams same as nicks engine in the 205 rallye richard said it needs 48s to get the correct airflow as 45s struggle after 230ish bhp

Bummer, mine may have to go then.

sorry my mistake for slagn off richard longman when the engine was set up on differant management and on a rolling road and not engine dyno.. and it didnt have the 13mm lift cams to make the 270bhp that it should have as colin advised that it would be a pig for road use thats why 11mm cams were fitted ....

You can't, 48s are a different casting and the butterflies would all need changing too. I'm beginning to wish I bought those ones off Pete when I had the chance.

With regards to the inlet design there was a 2.1 16v xu build which Sandy was looking over (not a unit he'd built). There was a before and after rolling road session recorded with the inlet design the engine had been built with, and then with the revised inlet fitted and map adjusted accordingly. The difference was huge. I have attached the link to the thread. Shows how important the correct inlet design can be on an engine!

Interesting reading, I wonder if it might be worth me giving him a call?

Im wondering wether or not to go in a new direction for my inlet manifold. Looks like there is some pretty compelling evidence that the Longmans/Jenvey one has some fairly serious flaws in it's design. If a different manifold design and a change of injector location can net a gain of 20 odd bhp then it's got to be worth looking at.

Mine are 12.5mm so roughly 14% more lift than standard cams.

Send him a PM, he is registered on here i think. Would be worth giving him the build spec and current inlet design and see what he thinks. Could possibly make quite a difference.

I should keep quiet really, otherwise if you do another day at Combe i wont stand a chance!

Ah, but your local knowledge must count for something, I've only managed about four laps there too. LOL
