Many Many Questions
Hey guys I have a few questions about Y/T products as I am keen to start throwing some at my s/c vs calais.
1. How much are Yella Terra's 1.9:1 roller rockers.
2. Is there a whipple conversion kit available for the L67, and if so, is it worth doing and what price is it?
3. What water to air intercooling options are available from Yella Terra and at what prices?

1. The newer style Ultra Lite rockers are $697 set inc push rods and mounting hardware.
2. It is in production, price not finalized as yet but expect $5,500 - $6,000
3. We have a stealth cooler kit 25mm thick $1980.00 and the Tower of Terra cooler kit 57mm high $2980.00 and we are working on an intermediate cooler about 32mm high to replace the TT, as there can be clearance issues with the TT.
Cheers.
Mark.

Far greater power potential.
The M90 is big enough to supply air for about 450 hp
The W140 can supply enough air for about 750 hp
First car we fitted one on is making 402 RWHP 299 RWKW
Cheers.
Mark.

What other modifications has it got to be making that kind of power?

It's a hamburger with the lot.
Forged pistons, ported heads, mild cam, roller rockers, custom pipes, CAI etc.

I have a question, are the pushrods included in the 1:9's available in 5/16"s?
I have a series 2 VY, and apparently the standard pushrods do not work correctly, not allowing for enough clearance. Thanks in advance.

You would be talking about those "other" rockers, the YT rockers have no such dramas at all. I run 1.95/1.84 spilt ratio YT ultralite rockers with the YT supplied pushrods with no problems at all!

Split ratio means, i'm running 1.84 on the inlet valves & 1.95 on the exhaust valves. YT have found that the split ratio is good for keeping the nasty detonation away and also yields good power gains aswell.
