supercharging pinto engine!!!

Have a look at Robin Hood for their Pinto bike carb ecu set up. Much cheapness!

My Engine is from 1991 and has run 40000 kilometers. My assumption is that the internals are in perfect condition. I have developed my own PCB to control the engine (Full controll over all parameters). I make use of a stainless steel inlet manifold (custom made and prepared for supercharger). I use VW Corrado G60 injectors, these can supply enough fuel. It is for me not easy to change the engine because of govermental rules (I can only replace it with an engine from equal type, I live in the Netherlands).
The amount of are suck into the supercharger is linear with RPM of the engine. This means that when the number of revenues go up (for eample 5000) and the engine efficiency goes down (less air in cylinder) there is more pressure generated and the air is pressed harder into the engine. The torque of the engine is almost constant over the entire RPM range.

When I use an over pressure of 0.4 bar (approximately 6 PSI) at the peak torque RPM (without supercharger). In this situation I get a torque increase of 40%. At this moment my torque is 165 Nm (Newtom * Meter), this becomes 230 Nm.
When I use the formula:
Power = (Torque * RPM * 2 * 3.1415) / 60
Power = 230 * 6000 * 2 * 3.1415 / 60 Watt = 144500 Watt = 144.5 kW = 196 bhp
The supercharger takes 10 bhp of power 196 - 10 = 186 bhp.

Do I make a mistake in my theory?

Try amazon...

I found the book a couple of days ago and have to admit he doesn't talk about supercharging, it's all about turbocharging a pinto. Still a good book though...

I know this is an old thread, but if anyone really cares but Ive supercharged, turbocharged, and ran nitrous on the ford 2.3 liter engines with great success and I still play with them! I have learned a lot and can help you if you are still interested. I currently have an eaton m90 on my pinto coupe from a thunderbird supercoupe and a 100hp shot plate under the carb.

I think we may be talking about a different engine here.
The OP would be refering to the 1.6 or 2.0 engine used in the UK and known as a Pinto. I suspect the engine used in the US Pinto car is something different.

Can anyone confirm?

I might be wrong but I think the US version of our Sierra XR4i (XR4ti?) used a 2.3 litre turbo "pinto" engine, but not sure it is the same block otherwise tuned 2.3 pintos in the uk might be more commonplace than 2.1s??? I think too Andy Rouse raced the US spec turbo car in the British Touring Car Championship up until Ford kindly invented the Sierra Cosworth for him to play with...

Have a look on the forum of www.turbosport.co.uk it's for old school fords, plenty of info on Pinto's etc there, there are a few Pinto turbo build threads if i remember correctly.

Could always sell the Pinto and fit a Cosworth YB engine, that'd be a lovely improvement!

Yea You are right, I forgot yall had a different engine....you lucky guys!! Ford blesses yall with the cool stuff....wish we had half of the cool stuff yall get!! The trick thing here is to find a Volvo B234F DOHC 16V head that was designed by cosworth for Volvo and bolt it on out "Pinto" 2.3 engines. It required minor machine work to make it functional but it is pretty impressive! Our "pinto" engines are also used in Ford Rangers, and mustangs and most parts are interchangable from 1974-2000 ish

Try looking at Corky Bells book on Supercharging. (http://www.amazon.com/Supercharged-Testing-Installation-Supercharger-Systems/dp/0837601681) Covers selection paramaters etc.
Also on MX5nutz.com there is a thread about using the mini M45 supercharger and modifying to fit an MX5. May have some ideas there.

I don't understand why you would do this. Wouldn't it be easier just to fit the Volvo 16v and turbo it? It's relatively easy, as Volvo made a turbo 8v.

Hello, I hate to dig up old threads but I have been searching for a long time on this topic. I have a 31 model A hot rod with a 2.3l pinto engine in it and I have a m90 that I want to put on it. I'm looking for all kinds of info on what I need. It is carbed and I want to keep it that way.
