Hi guys, ive been collecting parts for my 12v v6 to make it into a turbo but i was thinking of maybe just having an all out drag car so maybe changing to a alky 24v cosworth engine,
but there lies the problem, how do i change to run on alky? and with a kkk k27 attached to an alky 24v cosworth what BHP can be expected?

thanks in advance

Andrew

You need bigger injectors to run on ethanol, with E85 (85% ethanol and 15% gasoline) you will need at least 35% bigger injectors

With a KKK27 and 14psi you will achive around 400-450bhp. I don´t think the turbo will give more than that

well i believe that ethanol means you can run big psi set ups even with high compression?

your ethanol is that our methanol? or two different things?

what power can the engine handle then with a bigger turbo like a gt40r?

and will 1000cc injectors be ok?

Ethanol and Methanol are two very different fuel. Ethanol works much better for "daily" use and isn´t as hard on the fuelsystem and engine. I would not recomend methanol!

With stock cosworth 24v engine i guess you can get 500bhp but it can blow up anytime. I you change rods, pistons, cams and so on i dont´think 600-700bhp would be a big problem

1000cc injectors can handle 650bhp on ethanol

OH!, i can get methanol but not sure about ethanol, to be honest it seems to be a lot of work and money in comparision with doing a 12v turbo version, but its good to know its possible.

do you know if subaru injectors work on the ford v6's? you seems to always use bmw injectors what other makes work?

im actually in touch with a company who are experience in the 24v cosworth engines and they recon from about £4000 you could get a fully set up engine with managment pushing out 1200hp, interesting hey!

oh mikael im correct in saying that you guys just do this for fun your not actually a company are you? do you do work from people, if they pay of course?

Actually i often use aftermarket injectors. It´s hard to get hold on big injectors from a standard car. Don´t now anything about the subaru injectors

we are just doing this for fun, the fun stops when you are making a business of it Smile

You can easily wiki the both to see the differences, but just to make it even easier.
Ethanol is Pure Alcohol, good for you and your car!
Methanol is Wood Alcohol and you don't want to drink that, but your car can! Smile

If you are aiming a little lower, 323whp (Based on Mikaels Sierra with an original 2.9 12v turbocharged), then you can run on premium gas. It's fun and cheep to build and money well spent!

mikael, just a quick question about your bmw ford, you engine was the m50b25, is there a difference between that and m20b25? what you did to your engine could you do the to the m20b25?

sorry for off topic but thanks

Here in sweden the goverment wants you to use ethanol, but not really in our cars. The think we should buy enviromental friendly cars Smile

M50b25 has 24valves, m20b25 has 12valves. They can both handle much power but you need a aftermarket camshaft on the m20 to make as much as the m50b25

im not sure if it is in england, i looked an no where said no, so maybe,

oh thanks for info, looked up your dyno run, nearly 600bhp outta that bmw engine?? wow.

oh mikael never knew you had a soft spot for ford fiesta's :-) i liked your build actually im gonna give it a go i think , how much that cost you?

mikael the big question is capri or seirra! (or fiesta ah!)

on the topic of 12v turbo if your running 460hp which is what internals can handle does that mean if u used a 100 shot of nos it would blow the internals or does that not happen? im not nos expert to be honest.

thanks

I really dont want to think about what my cars costs to build Smile around 7000£ each i guess

Capri looks nicer but the sierra handles better

The problem with cologne 2.9 is the head gaskets, with around 460bhp they live on the edge, i dont know what strains there is with NOS, but i don´t think the engine will last long with 100shot nos on top of the 460bhp Smile.

The BMW engine is much better but it´s a hard job to mount it in a Ford

no money worries! lucky you.

i wasnt sure about the nos thing Razz

is the bmw engine living on the edge with 600bhp?

fiesta build past times hey!

oh actually have you ever thought about using water/methanol injection on your engines to increase boost? AEM do a cheap kit.

Yes its on the edge with stock interior. If i change the pistons and rods and so on it can easy take that and more. But it´s a small cost of course Wink around 2000-2300£ i guess

sorry for the thread hijack just wanted to ask your opinion on running a hybrid T3 from a cosworth on my standard 24V, what kind of power would it make reliably ? i want a fast road car it needs to be pretty aggressive on acceleration and boost up quickly, the only reason i chose a hybrid T3 is because i have one already and a standard 24V is still running on the original auto box.
cheers steve

To small turbo, your engine will have problems breathing and will lose durability with to much exhaust backpressuare
