15psi forged 347. not as much of a DD anymore due to me getting a bike now but i also have a DD, so my TA is pretty much DD/FUN car.

 

Running 9# on a forged 403 LS2. Good enough for 610 RWHP and I just went 10.16 and 10.17 Wednesday night.

 

8 to 10 psi mostly driven during the summer forged pistons scat crank & connecting rods 6spd

 

14 psi daily dr 14 mpg city 22 mpg highway six speed and speed density and luv it!

 

8 PSI with a true daily driver with a 100% stock LS2 engine.

 

14-15 psi on forged LS2/402

 

7-8psi making around 600rwhp. Does fine for tooling around town!

 

that is one bad *** caddy!

 

9 psi on a daily driver stock block, no problems, 3000+ hard *** miles its a second car that only goes out to get beat on

 

10lbs stock bottom LS1 making 623/513. I'm thinking about running 12-14 with the addition of a alky kit. Quiet a few guys on CF making 700rwhp on stock bottom LS1's. Its all in the tune!

 

very interested in seeing how something like this can handle a 2200 mile roadtrip or something like a long haul on the power tour. just having a problem on deciding which hot air kit i want.

 

7psi here. Stock bottom end, upgraded valvesprings, pushrods & fuel system). Turbo's went on at 89k and just rolled 103k just over a year later. Street safe tune and running great! It's been on a few 1,000 mile weekend visits to NY and back. Still gets 24-25mpg on the highway and 17-18mpg around town.

 

Thats good to know that its working good on the long road trips. This is one of my big concerns for putting mine on. Granted I'd rarely go on a long trip, but I'd be running the same 7psi on stock bottom end and have it be safe.

 

I have driven my car 2 times since I have owned it so I cant help on this one!

 

Same here, 7lbs upgraded fuel system, cam, pushrods, springs, and the stock bottome end is holding up fine. Ive gone on a couple 800mi road trips this year with zero problems in drivablity and reliability.

 

5 on low and 8psi on high. Mainly stays on 5psi. Flick of a switch goes to 8psi.

 

I am running 41 psi on a destroked 283 ci forged LS3. It has an LSX low deck block, AFR 215 cc LT-4 heads, and a GT3037586358014 on a T4/T6 hybrid canooter valve flange. The heads are amazing they are siamesed port cathedral oval port heads with 2 valve / 4 valve combustion chambers.

 

Your post= Epic Fail

 

that's my setup my uncles brothers nephew who put it together told me, he has built numerous 4 cylinders for the top engine builders in Nascar, and they just double them up and put them in the cars.

 

I'll be doing 8-10 lbs on my stock bottom end. We will see how long it lasts.
