Sounds fun though

Guess you will need a full 3" exhaust system to properly make use of one of these, as a 2.5" won't cut it..

the Harrop needs the 3" exhaust otherwise power will be around 330bhp

[ArticMonkey]

Swirl pot for fuel as joes upgraded pump didn't cut it on the RR map. Or get a 68L PA tank and bigger pump but that's ££££. I still think 2.5 would be fine. Maybe loose the cat for a silencer but for high end figures you might loose power. Thing is there's not many out there who've done this conversion. We need people to find out.

I do not have an uprated pump, but i do worry about starvation with the tank i have. I have just gone and got excited about it now... better commit : 1. Davemate

[NickB787]

Dave you will need an uprated pump I would recommend a swirl pot setup IMHO

[Mike (Cliffie)]

Swirl pot and external pump is mandatory for anything past 330BHP

Does it not also need the head porting as you hit a limit of flow?

All the stage 3 engines I've built were designed are ready for a Harrop

I already have an uprated fuel pump, and a stage 3 designed and built by Vocky

it a second fuel pump and fuel pump a major task?

[JG]

not really no, it can be quite expensive in parts though if you do it properly. see Jimmy's thread.

OK, I will get landed costs and won't confirm numbers till funds are sorted and everybody is happy.

[Zuber]

I was thinking of getting an SC conversion for mine next year (Jo and Lee). Would it make sense to consider this instead ? How much extra wonga are we looking at all in. I use mine as a daily, so it would need to be reliable easy, to drive etc.

[siztenboots]

A harrup SC would be no less / more reliable than any SC conversion. But it would have a lot of headroom for extra torque , whereas most are running the Eaton M62 flat-out , or even beyond its efficiency zone
