You'll enjoy that. My last Caterham was 400bhp.

 

Sounds awesome, how much boost will you be running?

 

If they don't use a MAP sensor what do they use? I was under the impression that most companies ditch MAF sensors in favour of MAP sensors.

 

Alpha N tuning - no MAP needed.

If the MAP is there i'd use it though.

 

I would defo use it. Maybe for a non boost application but with boost be silly not too.

 

Yep or you will be relying on the assumption you have fixed boost per rpm, which you generally do with a SC, but any belt slip and you will be overfuelling plus the MAP takes care of ambient changes in air pressure.

 

I would be wary of any company that wants to tune a car with tps based tables on an application that isn't both na and using itbs. I would always use speed density for forced induction.

EDIT

Also a point worthy of note, on a traction drive supercharger like the rotrex, the temperature of the oil makes a difference to the amount of boost generated and from datalogs I have it can be as much as 2psi.

 

Partial throttle won't be nice! If its a track only car then it won't really matter

 

The F20C engine is such a tight install in the Westfield, because of the engines height, and the low bonnet line, that there's literally no room for the factory MAP sender - it's the highest point in a Westfield.

Obviously, it could be relocated. But apparently, Westfield have gone with TTS & Omex's advice that it (the MAP sender) won't be necessary.

 

Last saw your car a month or so ago, when I was down at the factory; was looking great, love the colour choice by the way. Congratulations, should be a cracker of a car!
