O-ringed block with copper o-rings, mitsu MLS headgasket and standard ARP's have worked very well for me on my street car. I am running 41psi on E85 with a GT4094.
All those super high horsepower v8 drag cars must be really missing out:rolleyes:. How fast are you planning to go? 10's? a good factory restall is all you need, if you sweat high trap speeds so much, put a 5-speed in it. An automatic is all about ET.
So if 60AWHP is your point, then you are going to run the converter "locked up" all the way down the track? Or just lock it up on the top end for that extra .005mph?
Also if you play with the numbers just a little, things change. If my 26" tires actually grow or measure 26.5" at 148mph then the slippage would be closer to 8%
Those numbers are accurate, but the car is most likely going through the traps at around 9000rpm on the 148.9mph pass. It is a 11" converter and it only stalls to about 3800rpm without any boost, 5psi its about 4100rpm, and 20psi at about 4900rpm which is where we launch it. The car pulls...
The 4.422 number comes from the Mitsubishi factory assembly manual, go look it up. The Hughes converter is tight but it will spool a 67mm T4 and a 4094R without nitrous on a 2.1 or a 2.3l (somewhat slower on the 4094R). On a 50hp shot of nitrous the spool is very fast.
It works great, its my preferred method of shifting. Going down the track all you do is shift the 1st switch off for second gear then the 2nd switch off for third, it is very intuitive and easy to remember.
