looks good mate. is that a bogg brother manifold ur using? what you using for spark control?

its my mates car, but yes bogg brothers inlet and they supplied the modified carbs as well.
the igniton is done by edis 4 off a mk4 escort hcs engine. it just requires 2 powers and a earth to make it run

rs220bhp

This is mine, zx9r carbs with R1 fuel pump. Running on megajolt but soon to be omex.

scottyd

i have just got esc for mine. what you guys think about the esc system?

rs220bhp that loos good mate, how well does it run on the carbs? also you plan on selling ur megajolt when you go for omex?

that is the same as edis 4, it will run fine and make quite good power. but if you want mega power you will need a propper management setup

scottyd

thats spot on. not looking for mega power just now just want to get it up and running then start to upgrade parts and get more power.

rs220bhp

ESC is better than edis4 Edis alone will leave you in a limp home mode and has no advance.

ESC will advance slightly with the MAP sense connected

Yeah the megajolt will be for sale after christmas once the omex etc is fitted

scottyd

any more zetecs on bike carbs?

any one knoe what would be the best carbs for me? i have a set of r1 and a set of r6 carbs already. plan to run a 1.8 for the time being then move upto a 2.0after a while. what you be the best set to use?

I've seen the way you pedal that Clio mate, so you should be able to lay down some heavy competition to most folk at Knocky...

My old Mk3

here is a few i have done over the last year.

I know not all of the set-ups are fitted but as i was making them up for ppl i just took the photo's as they were near completion.

scottyd

nice one mate. its me that bought the 1.8 and carbs from you.building another 2.0 just now aswell. its just finding the time to do it eh.

cheers
scotty :P

I have my single seater/Zetec/R1 carbs now completed and ready for a test day. I simply fitted Weber main jets instead of drilling the bike jets. It is running Megajolt with the Eddis 4 unit and seems fine. Manifold by Danst in aluminium. Can't see how to attach images.

Nice engines.

wot sort of power do these make on bike carbs 1.8 and 2.0 ?

redturner37

My information is that they will be equall to a standard injection set up and without changing cams or anything will give 160bhp. I fitted them because I dont have room for the Zetec injection package without cutting chassis tubes and the Weber system is so heavy compared to R1 carbs and the alloy manifold. A set of cams should give 200 bhp.....

Is there anyway of identifying bike carbs? I have a set for my Zetec lump that I've been told are ZX9R parts, if I get some pictures up will anyone be able to identify them?
Thanks
Ben.

redturner37

Why dont you look at Danst Engineerings web site or see him on Facebook. He will have pictures up and he certainly has drawings of all his manifolds. He made the manifold for my R1 carbs in ally and it's brilliant craftsmanship. Well worth a look and then ring him.

mad73

is there any running probs on bike carbs , as i saw a fiesta on bike carbs and on tick over it sounded like it wanted to stool

redturner37

Absolutely not. Mine runs great and although it hasnt been revved in anger, ie up to full revs I cant see me having a problem. The main jets are Weber 180, (dgv) saves having to drill the originals and of course I can buy whatever size I require to get it set up perfect.

Adam31

My brother just bought this from a guy in Aberdeen, looks good. Any more info on it?

Adam

mad73

wot sort of cost would i be looking at to ditch my injection and run bike carbs? i found a site that sells everything that u need 750+vat would this b about right or could i save a few hundred quid getting secondhand stuff

redturner37

Not really qualified to answer this as mine is fitted to a single seater racing car However, mine cost a lot less. Carbs, air filter and manifold were about Ł300 and the Megajolt already fitted cost me Ł120. A few bit and pieces to complete throttle cable, bracketry etc, about Ł20. I did the engineering and a friend did the electronics....

mad73

sounds better than 750+vat,,, power wise would it b a power hike between 40 and 50 bhp to a std 1.8 and more if i do exhaust and cams would it squeeze around 200 bhp from a 1.8 and more than that if i use a 2.0 rs2000 engine

redturner37

A decent exhaust system and a set of cams will take you over 200bhp, but remember if you are going over 7000rpm, you should remove sump and fit some proper rod bolts, but they arent expensive. I would suggest the 2 litre as it has solid tappets and oil cooled pistons. You could look at Graham Blackwells site at Zetecinside for more info into tuning the motor and whats involved, a friend who has done it all.....

mad73

thanks for the advice i will defo look into this as power gains r good and a hell of a lot cheaper than going the turbo route.
thanks again

redturner37

and a lot cheaper than going the Weber 45 route.....

Im doing this conversion soon just a few questions atm ive got a 1.6 cvh efi wht woul i do with the vac hoses? One comes of the brake servo and the other goes in the inlet part just above where the brake servo goes in? Pleasee help!

redturner37

I dont need the vac hoses on my set up, but DanST engineering who did mine offer to put a stub on the manifold for the brake servo and for the MAP sensor as well, though I have fitted a seperate tail to each inlet port on the manifold. The hose should run straight from the manifold to the servo.

rhysdavis

im abit of a begginer here so what would i have to do with my vac hoses to get my carbs running right?
cheers mate

redturner37

Nothing really. The carbs will only feel a negative pressure when the brake pedal is pressed and this wont happen when the car is on the rolling road. The pipe will be required to be fitted unless the suction port on the inlet manifold is closed off or you will get a totally wrong reading and of course you wont be able to even road test it without the brakes working properly.

Here is my mk2 escort running zx6r carbs... i would suggest to anyone building a 2ltr on bike carbs to use 1000cc ones as mine feel a little restrictive at times...but as a starting point my mk2 kicks its arse out in 3rd in the dry off the throttle... only had it on the road 2days now but worth every penny and the stress lol...

redturner37

We had to lift the needles a couple of notches and that gave a very flat a/f ratio. Have you been to the rolling road yet, ?...What power do you think you are getting.

thefiestadude

ZX7R carbs, 1800 (130hp) silvertop on megajolt.
I've binned the filter and now run them open.

redturner37

I have posted pictures at Photo Bucket but cant seem to get them to attach to this thread.

tjRS500

How easy is it to get the megajolt fitted and running?
