Upping boost to 10 psi

Ok well whenever I get it out of the shop that is <img src="gr_images/icons/wink.gif" border="0"> . Having timing droped 2 at wot. It should put me at 17 i think. I was running 19 before i sent out the comp(still stock tuning). I can run 7psi on the street with 94 octane but I figure that is getting close. So 10psi will probably be a track only type deal unless i can find a place that sells 100 out here.

Good luck <img src="gr_stretch.gif" border="0">

I was able to run 10+ on 100 octane and 16° mid range, then ramping to 21° by 6200

And from what i've found so far in the motor, things were doing well. <img src="gr_grin.gif" border="0">

Re: Upping boost to 10 psi

I'm guessing 10 is ok, but i was pushing over that on many occasions.

I've tested the durabity of the head gaskets, and i was getting close to the edge <img src="gr_stretch.gif" border="0">

Do you know what your power level was at 7psi? Either that or the mass flow?

I am really close to giving Cartek a call to get larger injectors, up the boost to 6.5 - 7, and have them tune it with thier LS1 edit.

Re: Upping boost to 10 psi

I dont know the hp numbers but its hella fun when you hit the gas <img src="gr_stretch.gif" border="0"> . I'm running about 75psi(fuel press) at full boost. I figure anyway. Ordered my FP gauge today <img src="gr_stretch.gif" border="0"> . I also have #42 injectors. Which I think should be a must. I think 10psi and #42 injectors will be fine for my car.

Re: Upping boost to 10 psi

I was ramping up to 28' with 10psi on the topend and starting with 24' with 7psi in the midrange.Stock compression.
