On this engine buildup that I am currently doing now is leaving one thing that is making me wonder......what size studs should I use if I am going to run 13:1 C/R? I was told that I can run 8mm Bugpacks or Racewares as long as I got the case savers and I do have the case savers, but will it hold? Or should I run 10mm studs? It is going to be a 2387cc engine. Thanks, Chad  |

IMO If you have a choice I would go 10 mm!

Call Raceware and ask them their opinion. I did and I'll always run 10mm studs.

When I bought my aluminum bubble top Autolinea case I had the option of 8mm or 10mm so I went ahead and got the 10mm. The case also has case savers for 10mm studs included. So far so good on my 2332 and I like knowing that if I ever run a turbo or nitrous I got plenty.

Question, isn't the OD of a case saver the same size regardless if it's a 8mm or 10mm ID.

Yes, but I believe it uses a ½” insert |

The stock VW 8mm case has an insert from the factory. You can buy an insert to thread directly into the case and put in 10mm studs with no machine work. Scat sells a 1/2 inch fine thread insert for 10mm but the case needs to be drilled and tapped to use them.

Thanks, Chad Please let's all of us know about your stud size. You well see the black spots on the side of the heads when they lift. Good luck |

I'm running Raceware 8mm on my N/A 2276 drag motor. No lifting isses at all.
Same setup on several high hp motors.
There is a reason they cost so much money...

 Has any body had any success in removing the stock inserts? They were next to impossible to get out on my older Brazil case. This is a pic of my case where the stock inserts were tapped (on a mill) for 10mm. The cheap 10mm crmo studs are going in my engine, and we'll see how well it works. |

Martin,
How did the "cheap chromo studs" work out for you?

I have no experience with such high CR ratios, or aftermarkets studs, so take this for what it's worth, but I've never liked running 10mm stock studs on the street; the 8 mm seem to hold their torque better (in my experience).
My 1.5 cents.

I went with the 8mm bugpack raceware style chromoly studs. They have their regular chromoly studs, and then they have their race prep type studs with the 12 point style nuts.
