Winter Engine Upgrade

[Jon Green]

Hi Guys and Girls,

 

This winter I'm planning to do some modifications to my 2B+ engine. I'm currently running a 205 block 2.1 Pinto sucking through twin dellorto 40's, standard 4* 1987 vintage head and blowing out through 4 into 1 RH manifold and RH stainless silencer, standard cam and electronic distributor powered by Ford amplifier.

 

This was the set up that I took to SVA a few months ago. Before I'd even finished building I spotted an FR33 kent cam on Ebay, and it's lived under my bed for the past 18 months and so I think it's time that I used it! I'd also like to get away from the 4* head and having to use lead additives.

 

I would like to install the cam.

 

So my proposed set up will be:

Twin dellorto 40's

Injection head-Port matched and basic DIY gas flowed

FR33 kent cam

Same RH exhaust system (94 dB's at SVA)

Modified advanced curve as per Dave Andrews instructions

standard Ford amplifier

 

Does anyone else have a similar set-up..? same cam..? any estimates on BHP and driveability..? offer any advice!!

 

Cheers,

 

Jon

 

P.S. next winter's project is a pug MI16 engine transplant!

Mine was about 100 BHP at the wheels... but it wasn't a 2.1 & didn't run 40's... You should probably get about 115 bhp. Think it's similar spec to Longboarder who gets around this... (135 - 140 flywheel)....

Jon, Thats a similar set up to mine.

I have twin 40 Webers, FR32, injection head with larger inlet valves.

136bhp at flywheel, about 112 at the wheels.

 

Very drivable, loads of torque, I wish Id gone for the FR33 instead now, it should still give plenty of low down grunt.

Cheers, Bob.

mine would be the same , apart from 45"s. but standard head (soon to be sorted ) 285 cam, 115 to 120 est ?

[Guest salty_monk]

I had the 285 cam on standar injection head & a standard 205 block 2L. Using a 38 DGAS. Flywheel figure 121 on rollers.

Thanks for the advise!

 

Off to the scrap yard in the morning to search for an injection head.
