I know there's ball bearing turbos and hybrid turbos but is there any turbocharger that has little or if I dare say no lagg???


I was browsing through the net and OMFG look at this!


 

oops I should've returned it too a smaller size.

It's for a Fit! LOL......  

My HHR S/S has a Dual-Scroll set-up, with very little lag.
But I can`t say that you could buy one on the aftermarket just yet.
Of course direct injection could also help.  

Direct injection does help, but can it be tuned?... I think so, you just need a lot of money (bribes) to get the owners of companies to grant acces to the correct ECU Hex code and voila!
      But I was also wondering of working with the turbo itself. A racing blow off valve like the one on the Porches in the American Lemans, and those in Champ Car races sound like a loud "Sigh" Yet the only ones you get on the aftermarket for regular Turbocharged cars sound like "Psht." Which holds up air and releases it. Sounds cool, but its not as efficient. I wonder if they sell one of them "Sigh" ones or if there's a test between the two.

Tunning the Waste gate? External only desing?

Heres a tremeduously stupid Idea and I say that, because I think it has nothing to do with the subject and might be too expensive. How bout a turbo with counter-rotating fins inside the housing it'll increase the velocity of the air at exponential levels. Kinda like when two currents of air collide at the tail end of a Concorde at supersonic speeds. Probably too expensive and might not show much on reliability and performance, but so where the turbos of the eighties.... Am I making sense?  

every compressor needs to spool up.  There will never be instant boost with zero lag.  Even the smallest turbo out there needs to spool up.

BUT

Anti lag is the solution you are looking for.  When you let off the throttle, the turbo spools before you even need it.  so when you are back on the throttle, instant full boost response.

I'm sure most people know how it works, but just in case - it basically ignites a spark within the exhaust manifold / turbine, making it spool without having to give it throttle.  As you can imagine, this is ridiculously harsh on the turbine / manifold, so its only used on race cars.  you would need to replace your turbo once a month on your street car.  

Yes I've seen anti-lag on Rally Cars, and I like the sound of it, but it will destroy your turbo. Unless you're a fully sponsored racing team wasting about 2-3 grand a month isn't quite practical.  How bout a mini flywheel on the shaft housing with expanding counterweights that keeps the momentum in between shifts or in turns when you need to leave of the throttle? To stupid.... I know.  

master shake u need to become an engineer u r full of ideas that \i would have never thought of holy crap man u are a thinking machine!!!!!!!!!!!!!!!  

Huh?! If you knew what I did to keep my mercedes running all these years you wouldn't call me an engineer. I once de-gunked my engine using Royal Purple and when it sprang an oil leak from a broken gasket I had to re-gunk it.... Don't ask me how, lets just say it costed me .79 dollars a quart. and I bought a lot of quarts, (and a lot of trips to drop off stuff to get recycled at autozone.....)  

lol    thats crazy man u shold start a post called crazy ways to keep ur ride running  

dude throw a gt45r on the fit and lag will be of no concern haha.  No but in all seriousness what turbo comes with the kit  

It says that its a T25 with whatever comes in the picture.... Hmmm a turbo on the fit. (My mercedes had a turbo, but it was a diesel.)  
      Hey how come my mercedes only had 120hp when it was 5cyl with a T3 compressor? The Focus in Europe is almost the same thing apart from being gas instead of diesel. Would it of had more power if I put in (if it ran of course) Methanol based Biodiesel. Its leaner and more clean than regular diesel. (I see this website with a bunch of hippi-type colledge student making it out of used oil drums and fish tank pumps.)
      What I don't get on turbos is the codes they get. Is that the model number?....Or is it by manufacterer. T25, T3, T3/T4 (i know what that is.) GT28-30-36-..........102! Oh my how confusing!    

hey i bet ur benz had like 250lbs of torque so idk y it was so under powered like u said  

I never got back to you on that one did I? well about the power issue.....Do you know what I had to do to keep my mercedes running all these years?        Lets just say: You know you did the job right when it ran and you had extra parts in your hand! LOL I always said afterwards while the car was running "That went there, but where?"  I got to be the worst mechanic ever.... or the greatest!

I didn't know jack about cars when I started messing witht the thing and I was taking intro to auto in high school then and all I had to go by was old black and white pictures of buicks.  

Ive got another stupid idea about minimizing turbo lag. The problem is getting the compressor spinning more quickly. Variable geometry turbo tech seems to be the most practical everyday solution to date for daily driven cars, but VGTs still require a buildup of exhaust airflow to them before the compressor wheel really starts moving.

Why not mount a high flow air compressor just before  the compressor inlet and have it only actuate at part throttle or low boost situations? It would take a pretty serious burst of air to get it spooling, but it would only need to supply that airflow for brief periods until its really spinning on the exhaust airflow

A heavy duty alternator could supply the electricity for the air compressor and there would be no added parasitic loss. I don't know enough about air compressors or forced induction to say whether this is feasible, but it makes sense to me. the performance would be entirely dependent on timing,duration and intensity of the air compressors output, but thats nothing new in the world of tuning.  

I was thinking the same thing, but in the use of a pulley or a belt with a fan clutch based disengaging mechanism that..... --sounds too complicated doesn't it? Who cares!...-- would disengage at a preprogrammed level based on the theoretical view on when it should achieve spooling related to RPMs.

I love idea or think tanks like these. You just fling Ideas around until one makes sense.... yay for science!
