Cheers Ammo, but I am staying away from the messing around at the moment although if you come up with an adapter for that Cosworth single piece roller barrel to fit a K-series........ 😬 Oh and congrats on the 300bhp+ Emerald run..... David

I just can't help feeling that there is a huge margin put onto throttle bodies for what they are.... is there any reason why they are cast and not plastic moulded, they don't have to deal with heat there function seems simple.... unrestricted air flow direct to head, throttle mechanism, horns and filter..... or am I over simplifying things... force of habit!!!!! David GF04RCE.... every day is a Caterham day!!!! He heee!!... pictures here. Problem is every day seems to be a GT4 day too...!!!

I am starting to think about what throttle bodies I will put onto the K4 head I picked up from the MG auction.... a few questions... (basically trying to reduce the cost) 1) Why are bike throttle bodies so much cheaper and are any suitable for the K-series? 2) Is there any real competition to Jenvey/QED direct to heads? 3) Has anyone come up with the adapter for the new one piece cosworth roller barrel set up into the K-series, as discussed in previous threads...? (Ok not really reducing cost on this one ) It just amazes me how expensive throttle bodies are when they seem mechanically quite basic...... I guess it must be a volume thing....

Sugino An amazing example stunned I am, I hope this car comes to the UK so that we can all get a closer look at it...... Rear suspension is in CSR territory, I am still totally taken aback by this car...... For those that know Anthony... please don't let him see it, he'll only end up starting his car from scratch again.... David GF04RCE.... every day is a Caterham day!!!! He heee!!... pictures here.

There was a recent thread that showed an excellent small bar attachment to make up something that looked like a bumper... looked really neat and a great idea.......

Looks like you got two spotted in one trip....... Well done!! David GF04RCE.... every day is a Caterham day!!!! He heee!!... pictures here. Problem is every day seems to be a GT4 day too...!!!

Hey Grubbster, hadn't even considered that I might have to start thinking about re-packing.... interested to see the picks when you get them up..... yet another example of me utilising your handy photographic abilities in progressing my 7.... cheers!!! Might be worth a look inside as having camcoated my exhaust not sure I will see any straw colour effect.... David GF04RCE.... every day is a Caterham day!!!! He heee!!... pictures here. Problem is every day seems to be a GT4 day too...!!!

Never know what the appropriate recognition should be when you spot someone in a 7, whilst in a tin-top..... waved but I'm sure that can only confuse..... Anyway Nice hat!!!! A14 about 4pm Sunday...... David GF04RCE.... every day is a Caterham day!!!! He heee!!... pictures here. Problem is every day seems to be a GT4 day too...!!!

Take it to Dave at Powerspeed..... they have perfected it and make a lovely shaped hole...... GF04RCE.... every day is a Caterham day!!!! He heee!!... pictures here. Problem is every day seems to be a GT4 day too...!!!

Nick & Kevin, great conversions..... a much better way of doing it than just leaving the stubs...... David GF04RCE.... every day is a Caterham day!!!! He heee!!... pictures here. Problem is every day seems to be a GT4 day too...!!!

Hey Jonathan.... will be there next week....... David GF04RCE.... every day is a Caterham day!!!! He heee!!... pictures here. Problem is every day seems to be a GT4 day too...!!!

Dave F - the spec of the engine is a standard 1.8 Xpower 140bhp, which actually came in at a bit under 140bhp when first run at Emerald..... The best way of describing the change was as though the engine had just eaten a whole stack of airwaves...... I state again... get powerspeed to fit it, they do a really really tidy job on the hole cutting..... David GF04RCE.... every day is a Caterham day!!!! He heee!!... pictures here. Problem is every day seems to be a GT4 day too...!!!

Take the opportunity to jump to a powerspeed 4-2-1, you'll get 10% increase in torque and they will cut a wonderful stylish new hole for you...... there is talk of a bulk buy going on at the moment..... David GF04RCE.... every day is a Caterham day!!!! He heee!!... pictures here. Problem is every day seems to be a GT4 day too...!!!

You see I told you it wouldn't rain if I didn't come this time..... 😬 See my pictures linked below... I finally put up the Emerald chart showing the run pre and post fitting the powerspeed 4-2-1 exhaust....... The dyno curry is a great way to log the development of the upgradeitus addiction.... and see how where you money goes...... David GF04RCE.... every day is a Caterham day!!!! He heee!!... pictures here. Problem is every day seems to be a GT4 day too...!!!

10% Increase across the board.... CHECK out my pictures from the link below..... I have finally scanned in the graph of my before and after run from fitting the Powerspeed Exhaust.... Looks great and very satisfying knowing the money was well spent...... 😬 😬 😬 David GF04RCE.... every day is a Caterham day!!!! He heee!!... pictures here. Problem is every day seems to be a GT4 day too...!!!

Highly Recommended..... very happy with mine from the last bulk buy... Did a before and after rolling road run at Emerald, clear 10% increase in Torque and 4bhp increase, the plots look great against each other..... IMPORTANT: its well worth getting Dave to fit the exhaust, they do a fantastic job of cutting out the hole a really neat job..... David GF04RCE.... every day is a Caterham day!!!! He heee!!... pictures here. Problem is every day seems to be a GT4 day too...!!!

Cheers guys.... I think I'll have a go myself....... I have to do something as its just not right at the moment....... David ps I'll especially try and avoid the speeding bit.....well getting caught anyway....!!!! GF04RCE.... every day is a Caterham day!!!! He heee!!... pictures here.

Hi, I have standard adjustable blistiens and have just moved back from 13inch to 15inch CR500 (it was a winter tyre and money thing) anyway I think I need to adjust the ride height as I imagine when Caterham fitted my 13inch wheels they would have adjusted them as the fronts have a lower profile than the rears. What is the standard method of measuring ride height, and is adjustment as simple as turning the collars on the blistiens eg. two turns on each side...... just need to know how they work as I have not adjusted them before and don't want to do anything stupid...... Cheers David GF04RCE.... every day is a Caterham day!!!! He heee!!... pictures here. Problem is every day seems to be a GT4 day too...!!!

4-2-1 exhaust gave me a clear 10% increase in torque and an additional 5bhp. From a standard 140bhp 1.8 Xpower measured on the Emerald rolling road (138bhp actual) as measured when car was standard, to a second emerald run after a power speed 4-2-1 exhaust was fitted. I have a lovely graph with the two runs plotted and the whole line is shifted up showing a nice 10% increase in torque along the length of the curve....... very happy.... the best way I can describe it is as though the car has been fed multiple packets of airwaves.... Dave also made up a 4 into 1 converter attached to my old silencer for future mot tests..... David GF04RCE.... every day is a Caterham day!!!! He heee!!... pictures here.

There is always my alternative....... 😬 Check out this months low flying gallery or my pics have an example of how I got around the problem of mounting a bike to a seven......

Hey Bruno YHM and first dibs on them!! David GF04RCE.... every day is a Caterham day!!!! He heee!!... pictures here. Problem is every day seems to be a GT4 day too...!!!

aahhhhhhh I see..... thanks Ray I understand why I was confused now...... Doah!!! David

Hi Rossybee, my preference is to keep it as straight forward as possible..... so if you could find someone that wanted the tyres and it made up to the asking price, it could be possible.... David

Be careful, the advance planning function is a pain in the 🙆🏻 you can plan point to point in advance but if you are at point A and you want to plan a future trip between point B to C to D it can't do it without starting you at point A (your current GPS location).... David

Doah!! 😳 Well spotted..... Thanks... I think I might revise that to...... Less than 1k miles since new...... David
