Default Going with Cartuning turbo guys. Question

How much boost can this LS4 safely take? The kit is pre set to 7-9psi with water meth. They claim 500fwhp and 640 crank
Seems like a bit much to me with 10:1 and hyper pistons with stock rod bolts and mains. I'm thinking of just using 5psi. I like there kit cause its tuned and I have heard nothing but good things about Kevin and his work. I'm not going to go custom or anything like that I'm just woried about blowing the motor. I don't care aout the tranny. When it goes it goes
Just wanna hear what you guys think.
This kit will be installed in Oct since I'm still waiting on my heads and other stuff. My stock cam is going back in and intake manifold. Dod is gone for good do to my lifter swap and valley tray. LS6 TPIS manifold in the future but for now their kit makes more then enough power with stock parts.

I will call them on Monday and see what they say. I should probaly just run their kit out of the box as is. I am going to miss being N/A and will always wonder what my prev planned set would have made. No going back now... parts are sold minus CAI!

Good luck with the new plan, please post up progress as you go along.

Personally, I wouldn't go over 8 psi with 10:1 compression. That should still put you over 400 whp.

Since I've got the headers (still not installed), a rear mount turbo, ala Rossko, seems like an interesting concept - If I do that, all of my cars will be turbo...

I'll keep you guys posted for sure. Stuff just takes time. For now I am working on getting my stuff back together and preped. I might look for another block and work on putting parts together for it shortly after getting the trans reworked next spring. If it lasts that long.

Or you can just sell your headers for 650.00 since there new. LS6 intake and VLOM tray and use that money to put towards the Cartuning turbo kit. Again.. It makes more then enough power with stock parts!

I don't care aout the tranny. When it goes it goes
oh and it will

You should be fine with 8 psi. Go over to the turbo section and ask some of the guys over there, they are experts on the subject and will tell you how it is.

If your changing the cam and going turbo, what about the gt2-3 or 02 ZO6 cam? I think it was the ZO6 cam I was looking at?

I'm back to stock now except for my head work and LS7 springs. Just shipped my headers and sold my cam.
The cartuning turbo kit is more then enough, and if I want more I'll be forced to go internal. I did install non dod lifters and buckets with the the Kartec valley cover. Screw dod!

I think you and I were kicking some stuff around Dave about the fuel pump and using e85 instead of water meth....just be careful man...Mark with the silver monte ss had a chk valve in his meth kit fail and blew his ringlands all to hell...i have the rewire kit for the fuel pump too...and the 255 walbro...you will be good with the rewire...but if you want more power and safer all together...I would recommend doing the pump and the rewire and full time E85....theres some downsides with the corn juice though...like, have to tune for the "winter" blend...where its around E70...but a good compitent tuner can take care of that for you...its just a matter of fuel values....put simply..LOL...

and ive taken this car up to 10psi on e85 and still was nice and rich and making power....so its all in the tune guys...on 92-93 octane...I WOULDNT WITHOUT METH LOL...but the E85 gives you the constant source of octane!!

E85 sounds promising, but we don't have any of that stuff up here in Pacific north west Plus I would need to swap comptuers and cam gears from what I have been told. A new fuel pump is definitely in the near future and the rewire kit is a must for the time being. I'm not really too affraid of the water meth kit. I have a buddy at work who uses it on his super charged t bird, and he swares by it. I really don't understand what happend to Marks engine. Maybe we need to run a filter before to meth kit. The directions warn aginst running low on the meth and if we ever run out then we are supposed to re prime the pump. Stuff is scarry indeed and I'm thinking I might just stick with 5psi and play with a boost controller. Thanks Ross..
