It has done 10 psi easy on my stock long block LS2. I keep at 7 psi when my wastegate fittings don't come loose.

 

Do you have any track times ACCLR8N?

 

They work on 6.0's with small cams and lower rpms but run low 10's in few trucks but so did Foose '04's 4.8 ran ow 10's with the 4.8 and a little n2@!

 

My car is only 3500#s. And i dont really want nitrous. I want power on demand. I dont want to have to keep refilling bottles and such. With the turbo, itll be there as soon as i want it. Not knocking any one on nitrous.

 

Sorry, no track or dyno numbers. All I have are EFI-L data logs showing boost holding steady +/- 2 kPa and not dropping off. I can't speak to how it is at boost levels higher than 10 psi if that is your goal. Its great fun on my street car.

 

Would a TSP 228r on a 114lsa cam work well with the ebay gt45 and a lq9?

 

do you remember if it was a GEN three or GEN 4 4.8
