All FIRE engine cam specs needed

As the title says, i'm looking for all the cam specs for the entire FIRE engine range to create a database. So far i've been able to acquire parts of specs but nothing complete so i thought the more knowlegeable members could give me a hand on this. This is to help people looking to upgrade their cams and i have no personal interest in it, just want to make my site into a complete FIRE engine information source which is proving to be a little difficult

Thanks in advance

Re: All FIRE engine cam specs needed

There's 1.7mm more lift on a Punto 75 cam than a 60/cinq one from what I've been able to measure. Can have a play to try and figure out how many mm lift that actually gives you, if you like.

Re: All FIRE engine cam specs needed

This is one old thread!

No idea which cam the 999cc engine uses. But the P75 cam is avaliable fairly cheaply -- well worth a go. All I can say for sure is that it will fit. You may be able to gain more by si8mply using a bigger throttle body -- assuming the 999 is fuel injection.

C & B might offer some advice if you can translate the request into Italian.

Re: All FIRE engine cam specs needed

It´s a Uno 45s 1992, no fuel injection, carburator. I want to make it faster but my buget it´s low. I race it the uno. The only limitation is the cc and no turbo. Just a litte faster and reving. Want can I do using parts from another fiat´s? Thank you. Sorry for my english.

Re: All FIRE engine cam specs needed

I'd try cam. If it's not restricted, there is a category for the 750 car club (big, prestigious clubman scene, often frequented by designers prior to and after their F1 career) which hosts a category using the 1108cc FIRE engines. See here. Somewhere on the Guy Croft site there are photos of one such engine -- with a single "split Weber" (they were popular on racing Minis) and a long, long, intake manifold.

Alternatively, if carb per cylinder is allowed, you might try bike carbs (as small as you can get -- 400cc, maybe).

Re: All FIRE engine cam specs needed

Not sure what cam was originally fitted: you need to know that first -- the Uno secition might know.

Columbo and Boriani do lots of cams for the FIRE engines -- but they're not cheap.

I don't know the regulations for your races -- I think you'll need carb and cam, at least.

Some more here from the Guy Croft site.

yes but the 75 cam does not have the lobe to run the fuel pump which is mechanical on the carb engine.. can be done with a low pressure electric pump and using the mechanical pump minus the shaft as a regulator..
