Need more turbo So it's getting to that time where my turbo set up isn't going to make the power I want. Current set up is a on3 78/75, ls6 intake (waiting on my hi ram) 317's, Wally 450 and 80lb injectors, also looking for a bigger cam like a tu2 or tick stage 3 turbo. This is on my 383 with eagle everything. With this being a 6sp car I'm trying to get as big of a turbo set up as I can and not Waste to much time spoiling after shifts. What do you all think. Should I go to something like a s480 or buy another 78/75 and run twins. Goals for my set up is 1000whp and in the 9's. Oh and yes my fuel system is gonna change to something like a magnafuel 750 with 160's or 210's. Thanks in advance

Yeah there would be more fab work. I figured the motor would make up for the lag but wasn't sure if the big single would help or hurt with the 6sp. Of course there's that blue 6sp camaro in the 8's but I'm on a bit of a budget compared to him lol
It would take forever and a day to spool twin 78/75's with a stick and those cubes...Honestly at the right weight, you already have a setup that will run 9's and spool quickly. You dont need 1000whp to run 9's in a stick. That said, if you want low 9's you will have to move up in turbo. I would look at some of the billet/BB stuff to keep the lag down.
we have ran 9.40s with that turbo at 3550 lbs on a 5.3 and 10.31 with it at 4300lbs in a Silverado 6.0. for a 1000 hp it is not optimal but for a quick spooling street car that can run 9s it will get you there for sure.
9.40 run was 20 psi boost.

Thanks for the info. Does anyone have experience with either the tu2 or tick stage three turbo cam. I've sent out a couple emails to these guys to see what they recommend but would like some info from other sources as well. I know the tick has more lift and lsa seems to be better for boost but maybe there's something with the tu2 that just works. I'm not a cam expert just going off what I've read on here

Verdad Gallardo as far as cams go I will just say keep it conservative and it will run good. shoot for best average power not peak hp numbers . a good fast spoolup will out run a high hp slow spooling setup everytime. just my opinion but I do built street cars not drag only cars.
the Camaro that runs 9.40s has a isky triple 12 cam and runs great to 6600 rpm shifts.and will go from 7 psi launch to 20 psi boost in less than a second.
and for comparison we are installing a borg s480/83/1.25 /t4 turbo and doing a test to compare the two turbos.with no other changes except turbo and the downpipe

I'm not sure 78/75's would be all that hateful on 383ci. I run 69/73's on 325ci and its not bad at all. If he decided to go with a larger engine in the future it would be right at home with the twins. However, the S480 could easily meet his goals so it just depends on what he wants to do. That said if he decides to go with larger twins I would cam it more like its NA and rev it out since backpressure wont be an issue like it would on a single. I had a smaller cam single 7875 setup before doing twins, the big cam and twins went faster on almost half the boost.
If you have a two step to leave off the line shouldn't be bad at all. I currently run a 231/239 113 in my 5.3.

I agree a 2 step is a must. Track would be a different story than the street. I think it would be very laggy on the street, but you're right, if you cam it NA and are cool with shifting over 7k, it probably would be ok. I guess twin 78/75s just seems like overkill to go 9s.
Mines set for 7000 shift light and rev to 7500 if I need too and it sees that fairly often.
If you've ever been into imports what they consider laggy vs domestic guys is laughable. Coming from that scene I haven't seen a laggy domestic yet! Even totally out of boost our cars accelerate decently.
Absolutely overkill! Isn't that the fun we have modding cars?
