Bump



..


Reliabilty testing. All day in boost driving it hard at 17 psi for 1000 miles and counting on a stock engine. No issues. Wana see how much it handles before taking the gasket at 15-17 psi.

.. by the way i checked the ecu and it has a chip on top of a encryptor.. so the rom cant be copied. who makes em this way?

Im now running 18psi stock all day and been holding up. Headgasket hasnt blown. Ive reached my max on the 450cc
Runing 65psi Fuel pressure and getting 14's on the AF
been blending some gas with e85 to keep the af under 13 mid 12.

Beat on it and hold 18psi for miles non stop topping out 5th on a o2j.

If i have time this weekend ill hit the dyno on 18psi if i can manage to get some 650 cc injectors and run full e85. And see what numbers i get.
Then ill be satisfied and throw in the arp studs and a cam and see if it likes 24psi. I think its as far as id go on stock internals.

This again is a bone stock 98 cabrio Engine.
loving the o2j no more blown out spider gears lol.
I was having to replace 5th gear on 15psi.
