2 litre pinto hp gain

[Aodhán]

Thanks for the reply Alladdin.

I'm looking for a fast road with plenty of get up and go(145-160bhp). The spec I am thinking of is as follows:

2.1
Kent FR30 or Kent GTS1
Stage 2 or 3 head (maybe)
Twin 45's
Ashley 4-1 manifold

Any other ideas or improvements that you may suggest? Thanks again for all the help.

[Graham]

you wont get anywhere near 160bhp on those cams, 2.1 or not!

[Aodhán]

Thanks Graham for the response, with the spec I suggested what kind of performance would you expect? I am looking for fast road with plenty of torque, from your experience would you provide some suggestions on what I could do to achieve 145-160bhp and plenty of torque please ?

Any help grand would be great, thanks in advance.

[Graham]

the FR30 with the rest of the spec your talking about should give a very torquey engine which will still rev quite well, power will be in low 140's

[Aodhán]

I think that would be enough power for me and is there any additional information you could add that would benefit or improve the engine. Thank you again for your advice Graham, you have been great help 👍🏽 cheers

[Graham]

if you have a choice of heads the better head will always give more power everywhere in the rev range

Yes well I am looking at the Stage 3 unleaded head from Burton Power, would this be a good choice or would you suggest a different head? Thanks

[Graham]

Burton head is nothing special, but will do the job, but you will probably get a better head from vulcan engineering

I have just had a look on the above link for Vulcan although I am not on FB. It's good to see old school engineering values and heads hand ported in House which can be very time consuming in hours to finish the job. Most performance heads now have gone down the CNC route which I believe some of Burtons are.

Long may companies like Vulcan flourish in these very uncertain times and should I ever require a Pinto head modifiying in the future they'll be towards the top of my list.

Also the price between a burton and a vulcan one might be a little different

Thoroughly recommend Vulcan
I have a Vulcan Stage 1 head with a FR30 cam, on bike carbs.
Steve recommended this for my build as its used as a weekend road car only.
Very easy to drive and gave 153bhp on rollers last year. Plenty enough for how I use the car.

Anotjer thumbs up for Vulcan, Steve Curson is a pleasure to deal with and very open about his developments, no secrets like other builders, he did the head on my Pinto which made over 200Hp

That's the kind of power I would be looking for, what is the car like driving on the road, is it fast and plenty of torque? What bike carbs have you got? I was thinking twin 45's.

Thanks for the responses to get a Vulcan head, has anyone got a price range that a Vulcan head may cost?

[Erikmex]

Prices are on their website.

Engine has very good manners on the road. Tickover/idle is also smooth and you do not need to feather the throttle at standstill in traffic.
I drive around the Brecon Beacons area and the car pulls hard on winding country roads. If I want to have a bit of fun, the engine will also rev sharply, but maxs out around 6000rpm.
Carbs are either Honda Fire blade or Blackbird with longer custom intakes for a bit more torque.
Head is flowed with both valves standard and was around £1100 set up with cam included and supplied by Steve. Thus was around 3 years ago, so probably a little more now.

That's sounds exactly what I'm looking for indeed, that's brilliant thanks for this advice and help. Lastly what would the power range be like on the bike carbs compared to twin 45s? As I'm near sure I seen someone say before that the twin 45s are much better, any clarity on that by any chance or is it just people's preference?

Also who did you purchase the bike carbs from and what would the price be for such a setup?

I've never run this engine on 45s, so couldn't give you a personal comparison. However, my bike carbs were initiatially a pain to set up. Bought them off a local guy who had them on a Manta.
Manifold and trumpets were from DanST Engineering. He is very helpful and would be able to supply everything for you, if that's the route you decide on.
What I do find with these carbs is that the engine is very sharp on snap throttle.
If I had the money and was doing it all from scratch again, I would like to go down the route of throttle bodies. Probably Jenvey or Omex.
I'm not against 45s, as I've had them on other cars and they are really sweet when set up properly. I only went for bike carbs at the time as they were the cheapest option, where I had a budget to stick to.

Yes I understand , that's brilliant thanks for all this help. I have been in contact with Steve @Vulcan and think I'll be going for FR30 Cam stage 2 head with 45s or FR32 Cam Stage 3 head with 45s. So just weighing up my options which setup to chose? Hmm...

Thanks again for everyone's help, this is truly a great wee forum and I'm glad I joined 

We used to skim early blade heads 1mm on exhaust side down to zero on inlet, gave a good increase with flowed head without getting into piston/valve clearance issues, heads have dowels anyway and there's enough space round the studs.
They'll make 140+hp with a decent system like this, lost count of how many we did (to the point we kept early and late heads in stock ready to go) but never had a failure

[Erikmex]

Eh! none of that makes sense, what did you skim exactly??

[haadee]

I think he means they milled of the cylinder head face at an angle, to get a better angle on the inlet.

[snapper1]

The cheap(ish) option is to fit an injection head with a thinner head gasket then consider what cam you need and what carbs to use.
Bike carbs are a good option
