Hi Guys, In this engine I have brought I have a set of BD10's....

What kind of BHP can I expect from these before I need to change the inlet cam?

Cheers
Dan

 

whats the rest of the spec ?

 

Ok here goes...

200 block 4x4
Ported and polished head with kent competition lifters, 3 angled valve seats & bronze valve guides
GRP A headgasket (although set to change)
Belived low comp bottom end (although its going for rebuild before I run it as I'm not sure of its condition so better safe and all....so if its not already low comp it will be when rebuilt/before run)

Just that the heads only done a few k since having 1300 quid spent on it and going db14 inlet means i'll have to chance to double valve springs.....I'm happy at the 420-430bhp mark so whats your take?

Cheers
Dan

 

i would use the 14 inlet 10 exhaust but tbh 10s are ok but seem to promote a laggy feel and on a t34 when i used them my boost peak went from 4k to 4.8 k the standards will do 420+ on a ported head and a t38 but i think the best combo for that spec would be a 12 inlet standard exhaust cam

 

I agree 100% with you mate....thats just what came with the engine and its virtually a fresh head as it was only done recently and to a good standard. If It was me speccing the head no way would I have gone for 2xbd10's..

I might sell the pair and buy a single bd14 inlet...that way it'll set me up good for when i want to crank up the power at a later date..and the std exhaust cam is alright for 450bhp isnt it?

Cheers
Dan

 

yes the standard exhaust cam will cope

 

any ideas what the 2xbd10's are worth? and what a bd14 inlet is worth?

Dan

 

you can get a BRAND NEW from blank BD14 from woodford for £160 outright

 

Mine did 406bhp/428 lb ft torque on pair of BD10's and T34.63,has had headwork,L8 live mapped by MSD on greys,cams dialed in by MSD too
Rolling road operators commented on how nice the curves are

 

cool, was that with a 4wd manifold as thats whats on this engine and I was wanting to change it....but anything round about 400bhp i'll settle for as the extra 20-50 bhp I was looking at just isnt economic at the minute...so my 4wd exhaust manifold might end up staying for a while.

Thanks for the info guys

Dan

 

2wd manifold on mine
