Hi,

Could anyone tell me what kind if performance figures I can expect from a bog-standard 2.0L pinto EFI from a Granada in my Locost? I guess I will need to modify the EFI unit on top of the engine, will this have any detrimental effect on performance?

you may not have enough room under the bonnet for an efi inlet manifold without cutting it to bits! i wanted to use an efi system but was advised against it, im using a pair of twin webber 45 DCOE's now (well i will be) with some heavy engine mods, but in standard form the engine will still be pretty quick in a locost chassis!

that wasnt realy any help, sorry

This isn't much help either, but as standard the efi pinto chucked out about 10bhp more than the standard carb version.

I'm going to be fitting the same engine to my Dutton, well as soon as I get around to pulling it out of my Sierra! I know theconrodkid is also fitting an efi pinto and has tried cutting the plenum down to fit under the bonnet better.

good luck, I'm more worried about sorting the wiring than making it fit

Hello,
I can't tell you about performance (as I'm still stripping my 2litre injection sierra) but according to the very informative website of puma racing (http://www.pumaracing.co.uk/pinto.htm)

'The standard 2 litre was rated at 105 bhp (more like 100 bhp in reality) in carb form and 115 bhp with injection. Much of the extra power came from changes to the head design though as opposed to any inherent advantage in the injection system. So a good carb engine can be expected to show about 80 to 85 bhp at the wheels after transmission and tyre losses. '

So if you wanted to swap the injection engine to run off carbs instead you shouldn't lose too much performance. So you're onto a winner with your engine anyway.

I'd make a guess at weight of car around 650kg,
power output of engine (after transmission losses) 90 bhp

Gives you around 140 bhp per tonne which should be around 0-60 in 7 seconds?

It's a very rough, ready and pessimistic estimate. Your car may be lighter and the engine can be tuned up to give 120bhp or more, but I reckon it's always best not to get hopes up and then be pleasantly suprised. I'm sure people here can quote actual performance in their cars? Provoking response?


Cheers

Be warned: there are possible issues with fitting carbs to the injection head. The reason being that the inlet ports are pear shaped as opposed to the carb's round ports.
Burton do an adapter so you can fit a standard manifold:

It's £87+vat tho!

ChrisG told me a way of making a template up yourself though- designed using the inlet gaskets from each type combined.

HTH,

James

ive decided to go carb on mine now,im thinking of welding a blob on the manifold where the injector should go,thatl plug the hole

just use the genuine ford inlet manifold
gasket for the carb manifold and you should be ok done this to to loads of
ford capris when fitting the injection head
also did it to my own 2.0l capri and its done over 30,000 miles with no probs

Dax use standard Injected Pinto in one of their Rush. Even thought it sticks out of the bonnet a little looked OK. They said that it worked really well as you get all the benifits of injection for very little cost. Might be some pics on their web site.

See attached dax rush. Looks ok

Could even put one of those nice little humps in to cover it
Rescued attachment dax.jpg

perhaps im in a group of one, but that smacks to me of an afterthought!

looks bad

Make that a group of two!

peet bee,it was the lack of inlet manifold that cause a change of plan,the wiring is straight forward as i have the loom,the cutting down and rewelding wasnt a big deal either (till i chopped it toooooooooooo far)

Fair enough, it's not that I'm getting panicky about making it fit and then making it go, honest!!

I spent last night looking at the Haynes wiring diagram and think I know where some of it goes now.....

i used the loom from the car and the haynes manual for my cologne v6 and it started first time!

just make sure you understand what each wire does, put it where the manual says and you should be fine!

Thanks very much peeps, I think the DAX looks ok with the EFI unit through the bonnet. Is it SVA compliant to do that?
At risk of flaunting my stupidity, what actually does the alloy EFI housing carry? air or mixture? and what is the optimum condition (temp/pressure etc) before it enters the engine?

Just wondered what effect Dave Wilsons EFI mod (taking manifold out the bottom) would have on power.
Cheers

the majority of the stiky out bit is the plegnum chamber.

This is a big box that holds the air thats drawn into the intake tracts. The volume of this and the length of the intake tracts smooths air flow to improve torque / power.

If you shorten the tracts you can reduce torque, any mods to the chamber MAY affect power as its there to act as a 'buffer' to smooth air flow.

still think it looks a bit crap - a bulge would look better....

Thanks Steve,
I'm going to keep it as standard as possible and I agree, a bulge woiuld look better.

I think there's slightly more height in a Dutton's engine bay than in a locost and I could hopefully raise the bonnet a fraction too.
