Hi All,

Can anyone help me with info and tech stuff for a set of throttle boddies and ECU etc for my Puma ?

What do you need to know? I've got Jenvey direct to head bodies and Omex 600 ECU on my rally car - but it's only a 1600, so no VVT. There are spare outputs on the ECU which could be programmed to switch the VVT at a set speed if you wanted.

If you want to talk about ECUs, Omex phone support is fantastic - can't recommend them highly enough - so you could give them a call.

What specific info are you after, or just advice and other peoples experience?

Hi All,
Can anyone help me with info and tech stuff for a set of throttle boddies and ECU etc for my Puma ?

I'm currently converting a 1.7 to an Emerald ECU and throttle bodies - I converted a number of Zetecs/Duratecs before but for this project I'm undecided whether to use Jenvey bodies or modified bike TBs. If you're mechanically minded and doing the work yourself(ie not paying for labour) the bike TBs can be made to work fine (spaced appropriately, modified fuel rail, new manifold and linkage)-if not, you're better off going the Jenvey type route. If you want to keep the standard Puma immobiliser, you'll need to add a second Emerald/Omex ECU - either way you'll have to modify the engine loom. The VCT can be controlled by the ECU (eg gear change light) or if going for more interesting cams, the VCT is usually removed as in the case of the Puma, it's more of an emissions type benefit rather than power. I did a couple of dyno runs with the VCT connected/disconnected and found very little difference.

For the TB conversion job using Jenvey parts plus mapping budget between £1,800-£2,300 for about 30BHP - a bit more if you have a good exhaust manifold/system
More power is available if you change cams but the cost goes up as head/piston/valve springs mods may be necessary depending upon the cam profile - have a chat with Kent/Piper

PM me if you want to discuss this

Common Chris, make a comment about NOS lol

Thanks for the replies Im looking to make my puma a little quicker. Im told that better cams have been fitted, and a Puma racing Inlet manifole has also been fitted. Its running at 148bhp at the mo. I need to fine the best way to get to 200bhp with out losing the reliability to much.

Im up against 106, MGZ R, 205 etc with 200bhp ish. So any power increase would be a start.

Are there any gearing tricks ie using a 1.4 box to increase take off.

Any help, pointers is always good

Cheers

Could remove the toruqe limiter

Dom36 Give me a clue what thats all about

torque limiter* even

Its a restriction put on first gear up to a set number of revs to help protect the (gearbox I think)

Simple snip of a wire, or switch in the wire and it can be removed.

Notice how older pumas are slightly quicker? Thats becasue they have less restriction on the limiter.

You're not going to get 200BHP without compromising reliability somewhere along the line.

A 1.4 box will increase acceleration by lowering the final drive (3.8:1 to 4.25:1) though at the expense of max speed. Do you reach the rev limiter in 5th ?

My mod list would be along the lines of
Good quality ported head - don't just look at headline flow figures!
Throttle bodies
Decent ECU (Pectel, Motec, Autronic, DTA, Emerald)
Raise the compression to 12.5:1 (max for super unleaded)
Custom cam grind to your spec
Dry sump kit (pace products do one)
Custom pistons and rods
Lightweight flywheel with 184 mm (7 1/4" paddle or sintered clutch)
Oil cooler
Stack rev-counter (you'll be revving way past 7,000) and sequential shift light
Custom 4-1 exhaust, free flow cat (I assume your car will have to race with a cat next year) and 2 1/4 mandrel bent system
Quaife LSD with Quaife S/C gearkit (someone does do an IB5 5-spd dog gear kit at around £4000)
Decent 4-pot brakes, pads, fluid
Bias pedal box
Suspension such as Proflex, Chassis Dynamics, KW (competition spec)
Take out as much weight as the regs allow - and ballast in optimal places if underweight

That lot should give you in excess of 215 BHP - wont be cheap though
