Just got mine done. It's good. Very good.

The power increase is very noticeable, but what has stuck me the most is the smoothness of delivery. Throttle response is superb.

Hi Andy, cool board eh? :cool:

Sounds good to me, where did you get the manifold mate?

I ask because my ITG filter has coming up to 60,000 miles on it now and i am looking for a replacement, the manifold is the only original part of Scarlet's exhaust system left and i feel it is an unnecessary obstruction and the Trophy TB has been on the cards for a while now. Have you heard about the Vauxhall TB? Dieter has sourced a TB from them which is a straight swap and has a couple of mm more internal diameter than the Trophy one. It does need a custom bracket made up however to take the throtle cable. This is also an avenue i am investigating.

Hi Andy,

Yeah - it's pretty well featured too. It's like UBB but fast!

It's the original manifold. Mike re-welds the pipes to the flanges on the outside then grinds off all the crud on the inside and enlarges the bore a little (2-3mm). Obviously this isn't for the entire length of the pipe but it's a darn sight better than a wet slap for 3 hours labour.

It's fast. Much improved. He also had to grind out the inlet on the plenum because the TB wasn't lining up properly. Wasn't as bad as the other one, but it was still about 1mm across the top half of the inlet.

PiperX is really easy to fit (not like that huge maxogen thing!!). Mike's kit comes with a few extra parts from the standard box and it fits like a dream. The one thing you do have to do is drill a couple of holes in the bell mouth at the end of the feed pipe otherwise water will collect in it.

Sounds cool mate :cool:

Mike has obviously been keeping busy! ;)

Am on the lookout for something 'a bit special' for this years EU tours (Le Long Weekend and Treffen 2002). I have started with the fitted luggage and have made enquiries about Mike's Sprint Kit front bumper, hmmm last i heard he had a prototype made up, but the trail has gone cold since then. Any news mate?

Oh, this forum has an automated 'signature' function, therefore you don't need to sign off (you end up with 2 lots of signatures). Not a problem, 'cos you can edit your posts as well!!

Only thing this board needs is more contributors (MEGA need not apply!).

Oh, check out the fitted luggage thread for pics of my latest additions... :D

I found that out after I posted the message! Set it up then forgot about it. Couldn't be bothered to go back and fix it :))

I'm cheesed off with the entire troll thing on the MG BBS :mad: It seems to have taken what was once a thriving, supportive community in to essentially a "mine's bigger than yours" bun-fight. I refuse to get involved - it's pointless.

Mind you, I haven't seen anything interesting posted on there for some time ... :eek:

Anyway, you have mail :D

Cheers mate. Nice to get a bit of 'insider knowledge' ;)

I know what you mean about the MG BBS, its a real shame as it has by far the biggest 'membership'. The minority ruining it for the majority. :mad:

Still, this is a superb forum (if we could only poach some more members...) ;)

Also, the MG BBS is one of 6 MGF specific forums i visit, so i aint too worried...

Hey

I know this seems to be the modification of the moment. However, for those like me who know nothing about it can you list the parts needed and the work that has to be done.

I would like to put this on the main site as it's a very useful mod for those who are out of warranty. :D :D

Standard 48mm Body p/n MHB000080
160PS 52mm Body p/n MHB000261

Can get them from Rover, PTP, Mike Satur - the usual suspects. Expect to pay between £100-£120 excluding fitting.

It's a straight swap for the existing unit, so you have to remove the air filter hosing, and exchange the TB off the side of the plenum chamber. You have to watch the alignment on the plenum chamber though. Shouldn't take longer than a couple of hours as long as the alignment's OK!! It's also good practice to reset the throttle body once installed (ignition to position 2, then fully press accelerator 5 times).

...Latest news... :cool:

This just in from our Scarlet correspondent, ITG Maxogen ordered from Mike Satur on Thursday, also have made arrangements with 'Dieter the Data' for a GM throttle body (55mm bore). According to our German information, the GM throttle body is more involved to fit than the Trophy, needing some 'fettling' prior to fitment. 3 brackets need to be fabricated and the mounting bolt holes re-drilled to align with the the inlet plenum chamber.

Full details can be found here:

The info

Scarlet/Andy

Useful info - obviously relevent to all "K" series users. Had another look at the Dieter link - very impressive - lots of useful information. Therefore, don't plan to duplicate his site or yours for that matter on XPower.

You certainly know your MGF stuff!

PS. Did place the TB info on site!

Thanx, but i can't really take credit for all the work Dieter and his German pals have put in. I spoke to him about this on last years' Treffen tour and he was very excited, as it was the 'hot' topic for discussion on the German BBS at that time, although he hadn't fitted one yet (in fact he showed me an un-modified one he was intending to fit).

Dieter's web site is vast and a real gold mine of information, the majority of it with English translations (his English is certainly far superior to my German!;) ) I sometimes feel like we in the UK are lagging behind the Germans in the modification department, they certainly seem to be more willing to try a lot more 'off the wall' ideas, rather than just buying the latest and greatest from a small group of MGF specialists and MGR themselves. I mean, it had never occurred to me to try another manufacturers' throttle body on the K series, but the results from Dieter are very good indeed and if you are prepared to do the 'fettling', then there is no reason not to do it (especially as the one i am getting hold of is less than ½ the price of the Trophy one!!!:D )

Another group of people who are 'experimenting' at the moment are the Belgians. One of them (Eric Baekelant) has just fitted a Trophy splitter (from Smith and Deakin) AND a KH splitter! :cool: His web site is also worth a look, URL follows:

>> http://mgf.rulezz.com/ <<
>> http://mgf.rulezz.com/MO_EX_SP_SD_itfits.html <<

One of the problems with the KH splitter is that at high speed it can cause the front bumper to deform (it being a more flexible material) and this can lead to paintwork crazy paving. The Trophy one doesn't have this problem as it effectively stiffens the lower part of the bumper, although aerodynamically it is less efficient. By fitting both, you loose some of the ugliness of the KH one, gain it's extra aerodynamics and stiffen the front bumper - very clever IMO.

Andy, have you had a chance to get your car on a RR yet? (So this is where you've been hiding matey! LOL Long time no hear! How's the car, and how's it looking? Missed you at Silverstone last year)

Interestingly, the manifold mod is something that Rog told me about some time ago... so obviously a good idea with plenty of folks on a similar wavelength. Did you get to see the inside of your manifold before the work? I was startled at the restrictions that the manifold makes to the outlet airflow when Rog showed me one of his 'spares'.

The biggest question in my mind is how this modification compares to the EBD 4-2-1 manifold. This system has a HUGE reputation in Elise circles, and for the last year I've been meaning to get one for my F (you saw one with me Scarlet, at one of those Essex roadster meets). However, the problem has been with the lack of a flexible union. As the engine moves on its mounts under differing load conditions, having some flexibility in the exhaust system is a 'good idea' if you want it to last for any duration! ;) Up until now, the only solution has been to junk the cat in favour of a flexible union. However, the MGCC Sprint regs stipulate that if a cat was OEM, then one must continue to fit and use it.

However, I've had a brain-wave that should enable me to fit a flexible union in the system by hybridising a post-2001 exhaust back box to a pre-2000 cat on a 4-2-1 manifold...

EBD can be found at http://web.ukonline.co.uk/grahamf/index.htm

The big downer on this plan is cost and proofing new parts... oh well... ;)

Andy, my manifold will be better than yours, nah nah n- nah nah! ;) ;) LOL

PS loads still on the old BBS - but I agree, a question of filtering out the noise! :)

Oh, I've been a lurkin'. Been over to the MGBBS quite a bit, but I'm sick of the Ford Focus UK Product Manager clone chipping his mindless two-penneth in. He seems to have buggered off now though.

No rolling road test yet I'm afraid. I'll see what I can do.

Car looks pretty much the same if you saw it at Silverstone. Just a bit more leather and some of Mike's roll hoops as far as cosmetics go. I looked around for you, but I guess you must've been off sprinting!!



Oh yes - I saw the inside of the manifold. Didn't have the camera with me unfortunately, but in a word I would describe it as "crap".

The welds have been ground out now, so the openings of the pipe are no longer restricted, but there's room for improvement with the overall diameter of the pipes. I suppose this is where EBD come in. If I recall, Mike has had something in the pipeline for a while regarding the exhaust manifold, but the problem is getting someone reliable to make them!! So I went for the simpler option of grinding the "crap" out of the existing manifold - quick results, and I'm very pleased.

... and don't worry about your big manifold. I'll have my big valves and bored out head by then (although some would argue that my head has already been bored out ...) NAH NAH!! ROFL :D

:D Chuckle! Big valve head then? Hmm... been thinking about something similar myself- but this would need my doing some research into the 'Road-Going Modified' class regs.

Yup - I missed you @ Silverstone probably because of the sprint. I rematerialised at around lunch time for about 3/4 hour... found a few people then. Then I had to wait until the end of the day to catch up with those mad and hardy nutters who'd stayed arround until 5 pm! Bet they were glad they did; we got the opportunity to look closely at and under the Extreme MGF when they opened the enclosure to get the LMP675 car out... :)

I'm very interested in Mike's mod - from what you are saying you are getting quite alot of power for not very much outlay... Hmm. Certainly SIGNIFICANTLY cheaper than the plans I had in mind!!! LOL
