im going to be coating my manifold/downpipe soon… so in order to avoid having to do this twice ive been doing a lil more research to make sure my current turbo is up to what i need
the GT series DEFINATELY spool up faster and its very noticable. they boast full spool by 2200rpms direct from garret…what is your redline? id like to plot it out to better answer your question IMO
GT35/40R will be my next turbo. What kind of pricing are you finding on the 35R? I see them at $1225 shipped, which I couldnt justify compared to the full T4 I picked up for like $600.
Viper966 - If your car is only going for track duties, I would not waste money on the R sand save some cash. But if you venture to drive this on the street, the ball bearing will definitely make a difference in response (duh!) so if you can afford it, go with the 35R.
i am going to be purchasing my gt35R very soon for my SHO, looking at those dynbo graphs gets me all worked up because if a smaller displacement engine can spool that turbo by 5500-6200 then my larger 3.2 should be interisting with the 2900 stall converterit won’t be full boost but should be a pretty good kick in the ass on the launch.
I don’t know much about the SHO stall converters but to get the full utilization of the turbo, you might want to get that stall a bit higher. On my DSM, I have a 4000 stall and I can get full boost at the line (22 - 25 psi)…
that is the stock stall and with what i’m about to say you have to rember the sho community if a pretty small one, one of the few boosted ATX’s was recently(2 weeks ago) completed and he was running 330whp for 2 weeks and then he stripped the stator (he did constantly beat the fuck out of it as wil I) out so that is one worry of mine so i wil run a bit less power then him since the TC seems to be the obvious weak point although he is running a built trans with stock TC.
i guess my way of thinking is if a smaler displacement I4 can spool at ~4K than a 3.2 V6 should be able to spool it at a lower rpm and make good boost. i don’t want a higher stall converter because i like the driveability that comes with a lower one but i wil have to get a stronger one probably around mid summer.
Sure, the raw displacement is larger but you have to take into account airflow as well. I have 272 cams, a ported head, SS valves, etc so the airflow might be larger than yours/rev. I am not saying I am going to out spool you or anything but those factors play a big role…
