I would like to see pics of this rotating *** you speak of.....is she hot???

ohplz

well over here, depending on your taste, i nice rotating *** will throw u back about 350 - 450 USD

ohplz

well in our model cars here with the ls1's ls2's etc... we have a bit of a problem...

inbetween the tailshaft to the diff, there is what they call a " donut " which is a rubber thing that the bolts go through to aparently stop shudder etc.. ( its good in theory, but once u get over 400rwhp, they useless! ) and as im at 500rwhp, i snaped a bolt off it... so im getting the tailshaft extended, balanced and directly bolted up to the diff...

this is a picture of one, no mine.. as i kept twisting and distroying it!

you should probably go with a good set of dual valve springs and alot bigger injectors. what gas do you plan on running? meth?

ohplz

we have 98 octane here! (called BP ultimate) do u guys get that in the states?

ModularTurbo

iTrader: (14)

nope only 93 maybe 94 in some places

ohplz

hey guys just a quick question again...

im a little worried that the tc78 wont give me the power im after...

whats other people getting on there 346 forged + tc78 ( power levels etc )


i know its a great spooling turbo etc... but i just want to confirm power output on the 346/347 etc...

Several folks on this board are over 700rwhp with TC units and some I think have pushed over 800rwhp. If you want quick spool, compact size and awesome warranty...that is the unit to get.

they rate their octane differently, not apples to apples comparison of octane.

ohplz

yeah im not sure on how we rate our octane, but i know the guys here dont like running meth... god knows why... just dont like the risk i guess ( on street cars ) my current one is tuned on 98 at 500rwhp standard motor with the gt35r at 12psi ( 8 on low ) and runs fine! just snaps bolts and tyres really!
