anyone any idea of the expected power of a 2L zetec on twin 45s?
cheers 
Should be max 165bhp.
Why 45's? Already got some...
exactly
165 hmmm thats not too sporty
could you get more with cams etc?

i got 175 out of a 2l with 45s on properly set up it was a really sweet engine with loads of torque make sure you get them set right or you end up with a huge flat spot at about 2500 revs thats how mine ended up at the roling road drove me crazy an hour with a man in the know and it was sorted.

Bit nasty that comment, First car i built was a RH with a 2.1 pinto on 45's after spending a small fortune on the engine i got this up to nearly
170BHP, a standard 2ltr Zetec on 45's will give 165Max if setup correct, i.e carbs setup, mapping correct and a good rolling road session, if
money is no object then with better cams and a lot of headwork, good exhaust system, etc etc etc then +200 can be obtained, I run the 1.8 Zetec with
the 130 cams on 45's and it just gets to 155BHP which is more than enough for me in a little Westfield.
what model RH do you have, If the 2B variety with the heavy tube frame then why not go VX Redtop, more power output as standard and the chassis on the
2B will handle it, if however the RH is the earlier Stainless mono jobby then my opinion would be to stick with less power due to the body flex,
(i've built two of these in the past) hope this helps Steve
I had 173bhp from mine running on 45 DHLA Dellorto's with 36mm chokes. Not too sporty?? Was pretty quick as far as i was concerned!! Still - a 197bhp car was nice on a set of Piper cams when i test drove it.

yeah its the mono job! I could strengthen it up but that would kind of defeat the purpose of the extra power![]()
just looking at a cheap power upgrade from the pinto, XE is a bit more work and cost and just not worth it on this chassis.
All RH should be taken off the road they are a danger to other road users.
good for you....
I have a 2.0l zetec with some raceline bits that is about 165 bhp. Due for tune, but even now it kept up with the best that a recent Pistonheads run had to offer. At least until one of my cycle wings detached!

aye my pinto is fairly sporty (getting setup on the 45s at the minute) but I know Ill want more.
I think 200bhp is my ideal goal

Id put the money into management (griffin or emerald or something) if I thought there were bigger gains to running carbs but if I have them already
and they work well no point in binning them.
sure we will see how the pinto performs. was pretty limp before on the 40s so hopefully the 45s will being a bit of extra life to them 
Have you looked at the dunnel website? Thats what Pete has. Im sure similar gains can be had for less money.
I'm not going into anything about whether a RH is suitable for 200bhp as I havent a clue but if 200bhp is your aim then why not consider a
Duratec?? They give pretty much that sort of power without any internal mods and so must be worth considering when you do your sums. The exhaust exits
on the same side as the Pinto too so that may help.
Chester Sportscars had a Tiger Supercat with one in running on a Webcon injection kit and the standard exhaust manifold and that was quoted at 203bhp.
Not sure on what mods are required to get the engine to fit but it might be more cost effective that fitting a Zetec and then forking out for a ported
head and cams to get yourself 200bhp. The Duratec is lighter than the Zetec being alloy - i dont think a Zetec is significantly lighter than a Pinto -
maybe 15 or 20kg??
Some pics of the engine install here
This might be useful for anyone looking at a Duratec install

the chassis should be fine btw, few examples running v6s in excess of 200bhp
its also been on the road for 8 years odds so far so cant be that bad
BT - here is a present for you, come back when the painters are gone

Pleanty of Robin Hood owners clubs around,
Every model of Robin Hood I have looked at since the original Triumph 1500 based car has had a really serious design defect usually connected with
the front suspension. The 2b front suspension in its original form was particularly bad.
