TBIG Thanks Bruce it's Gone
TE44, 009's,, Razor Alky, Tial ext. gate. Was experiencing surge car would run well to about 8psi anything above that car would break up, boost gauge would get eratic,car would buck,alky would come on and off, now if I just put the pedal to the metal the car would run . Who drives around at WOT. Did numerous searches on turbo compressor surge. Seems like there is quite a few of us that experience this and live with the menace . There were not very many answers to the problem, lot of theory, hypothesis and opinions though. Except for one Mr. Bruce Plecan's fix that actually went against the majority of thinking.
I was at a loss bummed out, thought it was the ext.wastegate replaced that with no success, maybe a BOV but my friend uses one and it doesn't help at all, maybe a adjustable pres.relief valve before the VBC to adjust how fast boost comes up, get peak boost at part throttle instead of WOT. Then Dr. Boost responds toTurboJimmy's question on surge and the use of a BOV . Dr.Boost says one guy on here said that a Tornado get's rid of the problem but that most don't try it because it doesn't make sense. Well I'm willing to try anything at this point.
Actually a member here ROC87 had just upgraded to a 60 series turbo. He had earlier punched into the high 11's here at 1mile high with a smaller turbo.
He had Brian or Bruce one of the expert tranny guys I believe rebuild his tranny,new TC ,tranny built to the hilt, put his new 28" slicks on and went to the track. Thinking now that the tranny isn't slippin and with a larger turbo, and larger slicks for better mph on big end that he'd easily be into the low-mid 11's . Car experienced such bad SURGE that he was lucky to get into the 13's. He even had a nice shiny BOV on the up-pipe that didn't help with the comp. surge one ioda. Car was doing the exact same thing everyone else's does during Surge good to about 8psi then it breaks up, bucks like a bronco at part throttle. If one bypasses part throttle and goes directly to WOT car gets down the road. He was disappointed and parked her till the spring. Another local and member Bigair was experiencing the same when he upgraded to a larger turbo. He was thinking of putting the smaller turbo back on.The dreaded Surge.
Well all I can say is it may not make sense, all I know now is that I'm a firm BELIEVER now because it WORKS. Now with the Tornado inplace it has smooth linear throttle/turbo/boost response thru-out the entire rpm range. What a difference I was chasing my tail trying to figure out how to control this menace of Surge. Drop by your local PEP Boys and pick one up. They are made of Stainless and are tack welded don't have to worry about one falling apart and making way to the Comp. wheel and eating the blades. TBIG:biggrin: :biggrin: :biggrin: :biggrin:
TurboJimmy sent you a pm get model ki-100 it's 4" or 100mm should fit fairly tight in your hose. They actually are a tad bigger by a couple millimeters but compress to fit a little smaller hose that's like 3" 15/16ths- 4"1/8th.If your worried about it migrating put a clamp over the area of your 4" inlet/intake hose and tighten it just enough to keep it inplace you don't wanna crush it. Mine set right up against the lip of turbo inlet no way it could migrate forward as the inlet is beveled toward the smaller te44 compressor wheel. I did put a clamp on to keep it from migrating backwards which I don't think it will, it was in there pretty good and tight but with all the vibration and stuff it wouldn't hurt to put a clamp over that area of hose directly above Tornado. Might seem like Overkill but hey better safe then sorry. Yeah I'm excited that it worked so good, I was ready to park her for a season too, it was frustrating and there were no Answers to remedy the problem. TBIG!!!
