Yes Greg, I use the ford/cosworth stud kit on the TDIs and they work quite well. So is the new kit ford/cosworth/tdi??? LOL
no the cosworth studs #251 4701 number are CM , and are back cut , designed for a gas application and torque to 88 ft lbs they are just a little better then the use one time toss away head studs . they will not hold when you’re making any power.
I sent a block and head to ARP , and we worked on the correct length studs . In the mean time I found a stud that was .200 longer, and the engineers at ARP blessed it, we used it on Project X, and it healed the lifting head problem , you had to use two washers, but it was no problem and was a interim until we got the new length studs made.
We sold over 50 of those kits and had zero complaints; it fixed the issue without pulling the head.
The new kit was ready, and we started shipping the new kit # 204 4701 before anyone else knew about its nice when you have your picture of the ARP box, and in a few ad’s. We have sold over 200 of these new kits, and they are dramatically better on clamping load, and material. The new kit is ARP 2000 material, and torques to 125 ft lbs.
if you torque the cosworth kit to anything over 95 you have yielded the stud, ruining it forever . .
The TDI world has need a complete set of studs for years, I went to work and pushed ARP to make the product , the other kits are close behind.
Oldpooper is jealous of that; I’m not one of the groups of Nazis over there , and they openly allow any one of the right side of the fence to do anything they want , while jumping on my , not allowing me to show a piston, or a ARP studs kit .
I don’t sell parts , to TDI people , I am a racer over there , but it’s a one sided deal, and if you not in the click , then your on the outs ,
I’ve done more for the TDI engine in the last 8 months then most could imagine. Studs , pistons , rods , cylinder heads , and now I have a 5.0 V10 , wow , oldpooper , wouldn’t you like to know where that came from free , and its brand new .
I am under a mandate to achieve public relation Opportunity for the VW clean diesel motorsports application, and outside of TDI specific events , I challenge oldpooper to come outrun me at drag week, in fact, I challenge any one in the TDI world , in a TDI to come and outrun me , at any venue I go to , Hot Rod Drag week, Bonneville , and the Texas Mile .
Oldpooper where is the rocketcrap guy , and all his minions, come , want to put a little bet up .
$1000 , to the winners charity , to anyone that can come to Hot Rod Drag week 2010 and beat me
