well heres where i sit..

i bought a one off basically a copy of a TTi street..

i'm having a local stainless shop basically make me a jig and make some changes for me.. first and fore most.. the log is going to be 3" with 1 7/8 runners angle towards the turbo not straight in.. and it is getting a custom header mader for the pass. side 1 7/8 to a 2 3/4 collector and the crossover will be 2 3/4.. thw wastegate is off the end of the log.. turbo goes down waste gate goes straight out..

heres the only down side.. IF i had a stock K member it would limit me to a 3" downpipe.. however thanks to the PA i have room for a 3.5 off the 80mm

do you think having these changes are worth it?? i would like the kit to be capable of more than 600-650 but i REFUSE to go under the kmember..

this seems like the best option.. do you think the added tube volume will be enough to support what i want.. or should i sell this bitch and do my originle idea which was twin 60-1's

any other ideas?? i'm going to probably have less than 600 into the entire coldside set up.. so i figure its worth it..

that pass side header may be too big, as well as the cross over pipe. The reason why the log needs to be so large is due to the fact that both banks are running through that section.

very true.. so maybe stay 2.5 in that area?? with maybe a 2 5/8 primary

theres a thread about going to a 1 7/8 primary, and Jim(speed inc.) was saying its really not even worth it and it would contribute to lag etc., and this was for a 4xx build with an 88mm, i would say go no bigger than a 1 5/8 primary,

but what about the benefits of the 3" log

youre biggest problem will be the on center housing youre going to have to use. Thats the draw back of the street kit. ~600 rwhp is about the limit.

i tried telling you about the street kit.....as far as what you posted
a) those primaries would be way to big for the lil 346/7 you wanted to do
b)if you really wanted to do a 3" log and 2.75" crossover theres ALOT more volume you have to push to fill that....itd be ok id imagine when your leaving off the T-brake with the 4k+stall with a small shot,but around town it would be laggy and bla....
c)dont focus on the downpipe size as thats not the limiting factor hp wise yet
d)if you get that cam forget about this turbo kit,or vice versa your backpressure would be terrible....log header with large traditional split cam=no
just bolt on this kit as it is so youll have like $1500 into an entire turbo kit and run low boost on a stock shortblock with meth and enjoy it for awhile,get the car going and see how it does with that setup,then change the turbo kit around and what not if you want more.

ill call u later to figure it out so u can get the rest of your stuff bought.

low boost.. there is no such word..

Th 1 7/8 primary on the log isnt bad. I believe thats what the T76 TTi log uses, but the 1 /7/8 on the pass side is too big.

ddnspider

iTrader: (26)

exactly....it wouldnt make much sense running 2 different diameter pipes then u have to worry about uneven flow and backpressure.

Country Boy

iTrader: (24)

TTi does it with their T76 upgraded street kit? The pass side uses the stock manifold.

well hell i made 698 with a stock bottom end and a little spray.. if a turbo is that much easier than nitrous on a motor.. 7+ should be cake..
right??


i love this ****

With the right combination, yes its easy to make that power.

ddnspider

iTrader: (26)

so Ryan K had the wrong combo on his car with meth on a built motor with more cubes but with the "right combo" he's gonna pick up another 50rwhp?

Country Boy

iTrader: (24)

Where did I say that? Read post #6. I didnt say he could make that power on a TTi street kit setup. Ryan had bigger cubes, AFR heads, cam and meth to make some nice numbers. The street kit setup can only make about 600.

He was just asking about 700+ with a turbo kit, not a specific one.

ddnspider

iTrader: (26)

edit....Ryan did "670 with 18.7 psi at 4800 rpm that would gradually drop to 15.5 psi at 6300" he figured backpressure in the 40-50psi range.

and blacktransam was talking about that specific street kit thats why i said what i said.
