i see everyone around 8-10lbs of boost on a ls1 (10.5-1) with a d1sc, i keep forgetting my lq4 is only 9.5-1, wonder what kind of boost i can put in this hog?

 

if you are on stock pistons and no meth id stay in the 8-10 psi if you have forged rod and pistons......boost it to the moon

 

here is the only vid that i know of one of my 10 sec passes

I have seen that guys have been pushing the stock 6.0 truck motors a lot farther than stock ls1's as far as boost goes. I would say aim for 10lbs to start and go from there.

 

awesome thread

 

bump guys. these turbo builds are a dime a dozen

 

Here's my setup. Not an LS series engine, but a procharger nonetheless. Its a D1SC I got from EPP. Looking to dyno it this spring. There's just one pipe missing when I took the pic, but its all done now.

 

hell yes man thats cool!!

 

I started tearing the old stuff out of my WS6 this week... I would do a build thread, but I don't think anyone is that interested in a plain old run-of-the-mill D1SC build. I'll update here as I go.

Anyone else have a hell of a time getting the fan shroud out of those retainers on the radiator? It's like that badboy is glued on or something... I'm about to break out the BFH.

 

Yes it sucks. I used a hammer and a screwdriver.

 

Best thing to do is hit the bottom of the fan with your palm. Really hard lol. It will pop out.

 

Subscribed, Im going to be selling my NASA SU Series Championship Car so that I can complete my engine and SC my baby. Im going to miss my NASA car, but I hardly race her anymore. ( On the plus side, I want my TA to be at WHP level Im happy with, and I hope to one day hand the car down to my daughter who is currently 4yo and has a better tool collection then me already

 

Just had my Procharged car tuned last weekend with the 4L80 installed. Stock bottom end with the stuff in my sig listed.... 620rwhp/548rwtq. 13.7 psi at 6500, with meth of course.

Cant wait to see what itll do at the track.

 

^^ NICE NUMBERS!! makes me not want to spend the money on going forged

 

Spend it lol. Were on borrowed time and all know it.

 

man that big numbers!!

 

Nice numbers. My completely stock motor '02 Z28 put down 542/488 on 10 psi, running out of injector at 5300 RPM. Have upgraded the injectors and am going back to the dyno soon. Hope to hit 560 RWHP now.

 

10 psi and as high of timing as you can go without knock should easily make 560+. Do you run meth as well? Well an update on my car...I got into a small fender bender on sunday night. Its not to bad but it sets my plans back a little bit. Windshield needs to be replaced as well as the dash. Guess I need to wait to do the EPP cam lol

 

383 D1SC in a 70 Nova. almost done, still need to weld the pipes up and get rid of all the couplings and have the alcy/water pump checked out. it sat up for a year and now it is not working.
