Edelbrock carb tuning
Having roared around the south coast all weekend, I can tell the engine needs a tune. The IVA showed it running fairly weak mixture on tickover and at
2000rpm it isn't smooth at all. I knew I'd have to do something with mixture/jets/etc. as I took the Edelbrock carbs straight out the box
and attached them to the 3.9 RV8.
So, my question is, anyone know of a good engine tuning place around Southampton/Hampshire that knows their stuff on Edelbrocks and V8s?
Thanks
Tim

There are some good videos on the edlebrock website. However I still couldn't do a good job. I eventually got my brother over and he tuned the
idle screws etc. He has 30 years experience as a mechanic. No subistute for experience. I would be interested in what rods and jets are used if you
get if professionally mapped. I have a identical setup.

How does yours run?
I did think about playing with the jets, but I don't fancy buying lots of different ones to find out they're not right - plus I
don't have the kit to measure the exhaust output / emissions, etc.

You need to get yourself over to http://www.v8forum.co.uk/forum if you've not already done so....
I assume it's a edelbrock/weber 500?
If so, everyone will confirm that the carb is set way to rich for a RV8 with out the box settings. Same case for mine.
Can't remember what rods/jets I now have but definitely needed changing quite a bit and now runs much better (and uses less fuel too!).
Cheers,
Gary.

We use Tom Airey for pretty much all of our rolling road tuning. He's close to Southampton. He is in his seventies now and is proper old school.
There isn't much he doesn't know about carb engined cars.
Might be worth a call.
