It was done for the previous owner, I booked it straight in with Mark Shead to put a decent ECU on it as the loom was old and ugly and then he recommended the EFR and it all snowballed from there.....

Dave actually said the 9180 was a bit laggy so went back to A 7670, but since then has reverted back for some reason probably id imagine as he likes the numbers

Ive used Vince at Turbo performance and couldnt fault him for my c20let turbo

Caddyshack

When I was with him at the rolling road he said that he didn't find it that laggy for something that made such big numbers...oh well I still stand by the point that if there was a better product out there he would be using it already.

I know that feeling all too well ..

Mark Shead

Caddyshack

Yes mate. Since being on this Cosworth journey I have considered an Escort Cossie or a 3 door and I end up thinking that all too many of them will need a whole heap of work to bring them up to scratch, you see a lot of engines that have not been touched since the 90's

Caddyshack

Those extra CC's really make that much difference? No replacement for displacement

This was what I was thinking and look where that got me! Cracked manifold after 800 miles then absolutely terrible service when I went there! I would now recommend to do the opposite!

Caddyshack

Oh dear, who made the manifold?

turbotrev

Totall agree (with the turbo bit, I don’t know Dave so can’t really comment on that lol)

Cheers Paul

turbotrev

Why!?

You said you don’t even like turbo cars! Ha ha

Cheers Paul

I would buy either of those Cossies on looks and what they mean to me DESPITE their Turbo (which would need to be swapped to EFR and taken to Mark Shead )

I PREFER a naturally aspirated engine but as I also said before sometimes the manufacturer only made a turbo and I still want the car i.e. if they made a 330bhp Naturally aspirated Escort Cossie then I would take that over a 330bhp Turbo one.

In my opinion Turbo power is "dirty power" but it is a means to an end sometimes.

The best engine I own is my 2.0 16v in my 205 gti, much better throttle response and nicer to rev...it only makes 168bhp though.

My T34 0.63 powered car was a weapon on the road and made the same torque as horsepower on a harvey gibbs 400/400 engine.

Certainly better than my GT3076r engine.

If mapped properly then the t34 car is a weapon and mine peaked at 32psi and held 2 bar at the redline

Caddyshack

Interesting to hear. My friend has a GT3076r on his 500bhp YB and he said his supercharged 320bhp car (both similar 205's) would have trounced it in most instances as the 3076 was so laggy with and the std ratios too long for the car.

I found with my T34 that you waited for the boost and then when you changed up at about 5,500 / 6000 revs you had to wait for the turbo again on the next gear and if dawdling along at say 60 in 4th and accelerated then not a great deal happened, it was OK if flat out but anything less and it felt very lethargic, mine was topping out at about 1.8bar IIRC. Maybe my setup would have benefitted from a live map. We were originally just going to do that on the new ECU

My GT3076r was proper laggy and i hated it - it only lasted a couple of roads after finishing and back in the garage it went and got stripped.

My T34 was an animal mate - pull hard in every gear - i went from a t34 0.48 to a 0.63 and there was a little more lag but it more than made up for it in the top end as the boost didnt drop - was live mapped by ahmed and mark from grove and was a completely different car than when it went in.

Caddyshack

I have a feeling mine was an Ahmed chip as opposed to live mapped and you never know what numpties do to the car without having the map changed.

Mark Shead

It’s all relative to what you are used to. Once you have driven something better than you had you now see that it’s better than before.
Just like if you have no experience of it you can’t understand how it can drive better than what you have.

Mark

Caddyshack

Very true, I am still amazed how good my efr is and how much better the car is compared to how it was originally. I think more people should go in my car and see just how fast the turbo picks up.....will be even better on the stroker.

costina

iTrader: (1)

Such a true statement. I might even like how a efr drives but I cannot comment as I have never driven or been out in one.
Been in lots of cossies with different set ups and power levels best for me was about 12+years ago 632bhp 4x4 saff built by Norris Designs.

Its all about choice and tuning cossies has come a long way since the late 80's

Caddyshack

Come and try mine when it’s finished

turbotrev

I don’t wanna drive an efr equipped car now, imagine what would happen if I liked it ha ha

Cheers Paul

Caddyshack

All this negativity and you have not driven an EFR car? What is motivating you?

costina

iTrader: (1)

I will hold you to that Toby.

Caddyshack

No probs, any time. I will let you know when it is up and running

turbotrev

I don’t have any negativity toward them, it’s just not for my application.

For 550hp or below and if you don’t mind the cost they seem to be the setup to have

Cheers Paul

Caddyshack

Cool, mine will be 630 bhp if I use 7160 and I am not aware of a better Turbo. Although mine is a 2.2 it would make same power on the same turbo at standard cc but same spec.

turbotrev

I’m still amazed the little amount of cars I’ve actually seen that are running efr turbos, I go to a fair amount of Ford shows, track days and meets as well as know people in the scene and I’ve only seen maybe a handful, strange as they are so popular

Cheers Paul

Caddyshack

There are quite a few out there but not compared to the amount of Cossies.

Not that many are prepared to pay the money, I guess. I got through over Ł6k by the time I had done exhaust, manifold, turbo, ecu, loom, injectors and mapping and that’s without the engine being opened at all, you can do another Ł4k on a standard rebuild and another Ł5-10k easy if you add Long studs, porting, oil squirts then pistons rods and crank and you easy go over....hence my new Engine was over Ł20k plus vat. You can obviously re-use the crank at 650 bhp ish but it risks the rest of an expensive build if you do the rest without changing a 20 plus yr old stressed crank.

What power are you planning and what spec of build in terms of cams, head, pistons, rods, crank?

c20tbo

iTrader: (1)

Toby, whats a 7160 good for, im 7670 and aiming for around same power, im not stroker but long rod 2.0

Caddyshack

Sorry mate, it is a typo, I meant 7670, the 7670 maxes at 630bhp (ish) but stays very responsive, it is only about 500 revs behind the 7064.

Adam-M

Do you have a graph with your 7064 toby

Caddyshack

This was on a Mickey Mouse intercooler so Mark had to hold it back, it was also on a standard inlet. My cooling system was pressurising and he thought it might have been head lift...turned out to be fault pressure cap on expansion tank (sounds like racing driver excuses but all adds up) this was on the bog standard 2.0.<br/>

Caddyshack

I think the new Engine will do 525/530 on this turbo but may spool up a bit too fast on the stroker, Mark thinks the turbo might not hold the power past 6000 rpm so very likely we will go next size up on turbo.

costina

iTrader: (1)

Makes my graph a little slow on the uptake lol.

Adam-M

Does seem a good turbo especially if you had decent inlet cam, inlet manifold and inter cooler and ran it at 2.5 bar boost lol

I want to try one once mines is on the road I’ve convinced myself it should spool like my t3 but make power of a t4

Caddyshack

Yes, with those extras it would be it’s full potential. Decent pocketed pistons and crank you are not scared to rev it would do more.

turbotrev

No point in revving it anymore as it’s be on its knees come 7500, even earlier on a stroker.
Your just trading the top end power for bottom end power on that setup

Cheers Paul

Caddyshack

I wasn't thinking of revving past 7500, I was thinking of being comfortable revving it that hard. 7500 / 7800 is probably as far as I would ever need to go on any spec YB. I don't think the strokers need to be revved hard but think my new engine may have been mapped up to 7800??? Will need to check the graph.

I do not think I would be comfortable revving a bog standard engine much past 6800 on a very regular basis or for sustained durations / hard track use on a 20 plus year old crank with 500+ bhp, it is a highly stressed engine. I know plenty probably do though.

I am sure Mark Shead can comment but I think the turbo can hold 1.8 to 2.2 Bar at 7500 with the right spec engine. Surely you would not need as much boost to make the same power with a well ported head and correctly specced cams?

I think 800 bhp on here is expecting that his new engine with the new head will make a little more power with less boost and better response.


Am I right saying that most turbos could cope with an engine at 10,000 revs if they were only being asked to supply under 1 bar of boost?

Agreed on the Stroker, we are unsure at this point if the 7064 will hold power later in the revs so it is likely we will be upgrading it. It may well struggle to hold 500bhp at 6000 rpm... We are yet to see one this small on a stroker at this level although Mark has done a similar Evo.

turbotrev

A 7064 will just keep on dropping in power after that, prob even earlier if it’s a stroker, it will just run out of puff

Strokers don’t need to be revved but if you have a huge turbo and the engine is built right you could still rev the nuts out of it no problem, and make the most of your powerband if needed

Cheers Paul

Caddyshack

The stoker was built with a t6 on it, that’s a dustbin sized turbo

I know it will run out of puff on the 7064.

My engine aim is as much low down torque and power as possible. It did peak at 555ftlb on the old turbo but not sure what we will get on 7064 or the next one up.
