"challenge Spec" Gear Ratios?

[averyaaron1979 0]

anyone every heard of challenge spec gear ratios and know what they are set up like??

 

found that a set is sold from the likes of abmotorsport but i can't find anything on what the ratios are.

Probably best to give Andy a call to see exactly but probably one of the following:

 

either std Be ratios (1.9 or 1.6) with a 4.8 cwp - used in the std 1.6 challenge

 

or the Quaiffe close ratio hybrid box used in the 1.9 challeneg - think this would probably have the 4.8cwp as well

 

Hope this helps

cheers for that, just trying to work out how this would affect my set up with running an xu7j4 engine which shall be tweeked to roughly 170bhp.

 

may be good for sprinting

Depends on the cost. I just run a standard 1.6 box in my 170bhp Visa. 1st gear is a little low but then I have 13" wheels. May be cheaper to get a 1.9 8v box and a 4.4cwp from a Mi16 and have some rebuild it, that will give you the best gearing with a low enough top end and a long first for the starts

They use a 4.88 diff in the challenge all info can be found from this link.

your talking about the gearbox on ebay right? i looked at that aswell, said it required a diff as the lsd had been removed.

thats the one, they stated it was from yukspeed who show no parts for pugs either. the seller doesn't know what spec the ratios are either 1600 or 1900 but i think it's too far for me to travel on a hope

I remember a while back there was a box doing the rounds with this so called gear set fitted so a mate of mine bought it only to find out it was a std box so prompty sent it back, Cannot remember which dealer he got it from now thou

I sent him a question thorugh ebay about this to ask if the diff had been sold with the crown wheel still attached & if no what numbers were stamped into the crown wheel but he hasn't replied so I didn't bid.

 

I spoke to him last week about his 83.5mm pistons & liners but that was only a bare block with the pistons, liners & a water pump but no crank or rods so I left that as well.

 

Graahm.
