camshafts

ross261983 · Nov 25, 2009

what are the best possible camshafts to get for 172 ph 2???

Gray · Nov 25, 2009

open question...

what are you wanting to achieve?

ross261983 · Nov 25, 2009

more power

Gray · Nov 25, 2009

LOL!

what spec engine are you building?

mini-valver · Nov 25, 2009

Road car? Standard pistons and valvetrain?

ross261983 · Nov 25, 2009

172 with throttle bodies

K-Tec Racing · Nov 25, 2009

CAT 421 cams work well. 215bhp ITB's 421's

work well, linear power delivery.

i find them a bit too peaky ye olde 421's

f**king LOLOLOLOLOL they're far from peaky!! they give masses more mid range than 428s

Fred@BTM · Nov 25, 2009

this was on a car with stock (ported) inlet, it had NOTHING until 5.5Krpm, they might of been 423's i forget (BB's old demo car)

sideways danny · Nov 25, 2009

probably a dogshit map. IIRC they also retarded the exhaust cam a lot to make it idle on the stock ECU

421 cams, ITB's

Nice spread of torque.

Fred@BTM · Nov 25, 2009

pretty sure it had 423's thinking about it, was on stock timing though this one, idled at 1200ish IIRC, but was naff below 5.5krpm, just nothing, nothing, nothing, nothing, goes mad, limiter, nothing nothing nothing etc etc

i'll have a search through and see what cams it had

K-Tec Racing · Nov 25, 2009

that sounds more like 423's which are way too wild for a stock engine

Fred@BTM · Nov 25, 2009

you mapped benP's engine?

K-Tec Racing · Nov 25, 2009

that was his old engine, not the new one........ we power ran it as it was mapped after we fitted bodies about 2 years ago with its previous owner.

characteristic of a map designed to make you think a car is fast. make it flat as f**k, then bring in the power hard

Fred@BTM · Nov 25, 2009

what when it was still Stoodies?

no idea on the map danny, bottom end was rogered anyway!!!

sideways danny · Nov 25, 2009

Fred said:

no, philty had the bodies fitted. Ben brought it donw for a health check and a power run, and to have the pops and bangs removed

Fred@BTM · Nov 25, 2009

ah yeah i remember, philty bought it off stoddie, then ben had it then rebuilt it

K-Tec Racing · Nov 25, 2009

yea, then didnt like it and broke it and sold it

Fred@BTM · Nov 25, 2009

(again!)

sideways danny · Nov 25, 2009

not that he's easily distracted or anything

K-Tec Racing · Nov 25, 2009

std 172 with itbs, vs itbs and 421's

K-Tec Racing · Nov 25, 2009

btw its not turbod... footer on graph hasnt been changed.

Fred@BTM · Nov 25, 2009

or the date!

sideways danny · Nov 25, 2009

Fred said:

that's today's date

the comparison graph was JUST done

Da · Nov 25, 2009

So are 428's a good all round compromise for basically a stock engine with a remap to suit?

Tucker · Nov 25, 2009

are you mapping?

sideways danny · Nov 25, 2009

Tucker said:

no. I meant the comparison graph was just created from 2 old power graphs

K-Tec Racing · Nov 25, 2009

428's are currently the only option in that range to run on stock managment

421's or above wont idle

Brian172 · Nov 25, 2009

I was thinking of getting 428's fitted and mapped and then at some stage getting throttle bodies.
Would it be best to just wait and get 421's at the same time as the TB kit?
Is there that much difference between 428's and 421's with throttle bodies?

K-Tec Racing · Nov 25, 2009

K-Tec Racing · Nov 25, 2009

about 10 bhp

Brian

I would always start with the management as then you have an open book as to which direction to go

So Yes personally I would wait

Dont bother with cams and TB's in combo.

For the total cash of these you could just about have a supercharger conversion kicking out 250 bhp with the potential for silly power

marinemackay2003 · Nov 25, 2009

^^how much would it roughly cost for ITB's if i already had an omex 600 and 421s fitted ect as like the lok of the graphs i have seen noise aint bad either

feel free to pm please Mr K-Tec (Andy)

I have thought of the idea of a super charger kit.
Im not after huge power though, but it is something im looking at.

K-Tec Racing · Nov 26, 2009

Brian

Yes..

SC power isnt HUGE! but it is very fast.... but very tractable..

As Andy says cams and itbs are close to SC low boost cost... but they are different in delivery..

camshafts

mini-valver
