Everyone on SF seems to agree the sequential isn't the best on the #2 life of the turbos. It might be great on stock boost but when you raise the boost it changes the game I guess.
To me the risk wasn't woth it and lag wasn't bad, so went with it.
On the exhaust its like giving it a bigger...
the ecu controls the timing on the valves, you have no control over it. You can only control to make sure then work.
I was talking gaining power from removing the valves, I have no egvc or iacv anymore
hahaha
But seriously what would not function correctly on the Sequential system to cause it to be more prone to blow #2? Only think I can see is if the timing on the EGVC and the IAVC arn't right cause surge or IAVC opening too early or maybe even the EBV not opening so the turbo is at 0 rpm...
ahh Reading off mkiv simply have the valves wrong.. If the EGCV was opened without the IACV it would surge, with ebv the flow would be Fairly minimal but it really wouldn't spool up the turbo, maybe a few thousand rpm if that as the exhaust as no where to flow as the egvc is closed..
If the turbo is spinning and the compressor isn't flowing it will surge, just like your throttle body closed when the turbo spooled.
Because 1 turbo is Flowing 15 psi. If you add in turbo 2 the flow is cut in half for each turbo. I probably shouldn't say overspin, cause I dont have a...
so #2 will surge until 4k when the iacv opens.. sounds like a winner to me..
Still doesn't do anything to counter act the #1 turbo overspinning to create 15+ psi in the intake
yes it does have more torque from 3000-4000 but its not that big of a difference..
I did have everything for the TTC I pulled it all off as the downfalls of the system outweigh the benfits..
running the single #1 turbo at 15 psi is like running the twins at 30 psi.. The single turbo is flowing 2x the amount it should, on elivated boost levels it makes it even worse...
ttc seems like bad news with a modified car to me..
say you're trying to boost 18 psi on the first turbo.. you'll be overspinning the turbo till ~ 4000 or so when the 2nd turbo kicks in shortening its life.. then the rear turbo goes from 0 rpm to 120k rpm in a split second... that isn't good...
so you're going to be running a walbro in to the 044 in series? Sweet I cant wait to see how it turns out.. I was thinking about this setup for my 1.5jz to get to use like 720cc injectors..
I never ran my twins on sequential but ttc is fine imo.. I was comming from a 67 1jz, so lag wasn't noticable at all to me..
TTC will keep your #2 alive longer though
