Dynoed the 74mm Part #2 - New Best 1000AWHP/716TQ @ 48psi!

Nice power man I thought you had enough ponies already.

Thats a great idea. At what power lever did you find yourself having issues with the head before? What did you machine the dowels out of?

I would say it is a benefit to anyone running higher than 30psi and having head stud torques above the specified 86 ft/lbs.

I have not seen a head as bad as mine for casting deflection and elongation of the boreholes and seat crushing; but I have seen many with the symptoms and this part is also a good way to repair a cylinder head that has crushed seats or fixable damage so you don't have to throw away an expensive cylinder head.

How about a mass production of these to help all the high boost guys out with another great upgrade and more piece of mind about their build

I am already on it. I am going to do some testing and development first though to confirm product design is good or if I need to make changes in dimension or material.

So sick Tim, congrats!

 

[viperlp01]

Ill help test for ya Tim. I had thought about the idea but I decided on keeping head stud torque at 85 ft/lbs and let the 1/2 in head studs do work. BTW congrats man.

Nice job Tim! You have one mean car! Wish I could see it run at the shootout this year.

So your the one who got them cool looking slugs from a machinist i know, im not gonna say who as its up to you to tell or not but i know now what those things were for and i may need a couple sets if they work out.

 

[Miasma]

I too will be interested in those pieces. Please keep us all informed on the testing?

Congrats on achieving the 4-digits. Very well deserved. Hope to see it put down a good show at the shootout.
