It's your wallet. Good luck.Well Donnie I have the JS box, it should warn me and take action to prevent the damage from even starting. The main thing is to have good street manners with good spool up.

Using the alky with the pump gas is a for sure. The sim runs with the pump gas look ugly. Don't run low on that alky. You gots no safety cushion, except for your JS box.You are correct, I will attempt also to find out which cylinders are knocking, by upgrading my fast dash to 1000 frames per second, if it does not work I'll find out in a hurry looks like. I am still going to go for 9.5 to 1, I may have to use alky now though.
That is a valid point however, I can rig up something in the XFI to prevent boost from rising without alky pressure pressure present, I will have to come up with something for sure. On another note I will be changing the rear axle ratio to 3.89, this might help also. What do you think?Using the alky with the pump gas is a for sure. The sim runs with the pump gas look ugly.

A lower gear will allow rpm to rise quicker, possibly allow boost to rise quicker. As long as you have a good boost control system, you'll be OK. You certainly can't afford to have a boost spike when running on the edge.That is a valid point however, I can rig up something in the XFI to prevent boost from rising without alky pressure pressure present, I will have to come up with something for sure.

I wouldn't call trying to skirt the limits of one's static CR, thinking out of the box. That's a very common occurrence by those that just don't know better. I myself was guilty of the same thing, and have the scrap metal to prove it.Norbs,
I'm glad to see your running something a little out of the box although I don't think it is as sensitve as Don would make it seem. I'm sure Don would agree that you don't go faster doing what everyone else has done.

I'm afraid you right, however I want the engine to be responsive OFF boost, I do not like lag at all. I'm limited to converter because of the overdrive I will not be able to loosen the converter at all, right now stall speed is 2500 off boost which is perfect for driving around. Is 9.5 to 1 going to be that risky?I'm afraid, Norbs, that what you'll end up with is an engine you'll be scared to push on. It's a completely different state of mind when you're pushing on an engine that has a clear limit, compared to pushing on one that proves to be almost impossible to blow up.
I'm sure that 9+ to one in a modern supercharged engine doesn't necessarily translate to a V6 designed in the 70s, but it sounds encouraging. Is Norbs going to be upgrading the design of the Stage II V6 to the level of modern engines now?Don,
I know you're concerned about running a 9.5 to 1 compression ratio in a street car but you're aware that GM builds factory supercharged engines for the Cadillac CTS V and the new ZL 1 Camaro that have a static compression ratio above 9 to 1 don't you? I know it's not a Buick but I'm sure GM did their R & D prior to deciding on going with that compression ratio in lieu of something lower. These engines come with a 100K warranty also.
