I have a k20/eg hatch and I am starting to build a block for a huge power turbo build. I have been looking around at turbochargers and I cant seem to find many dyno charts and specs from people setups. I am looking at the t3/t67H.O. turbocharger and I have seen how much power it makes on a 2.0 b series motor but I haven found anyone with a k20 with a turbocharger that large or anything close. I am trying to get a rule of thumb I guess, I am looking for a turbocharger that will support 650whp or so and will achieve full spool by 5-6k. A guy from a near by town is making 750whp on the t3/t67H.O. but this is on a 2.0L b series but I dont know when it sees full boost or what psi he is running. I do know that he is reving the motor to 9500rpm so I would guess that it has about a 3500-3000rpm power band.

I hope my question is clear, I am just looking for a big power snail that will see full spool by 6k. And if anyone knows, how much faster a k20a2 spools a larger turbo than a b series if any.

 

Get the T67 Ptrim and a lil shot if nitrous.. it will make 950+whp

Damn, I thought you ment you made 650 on the k20a2

Thats not a k20???

 

i hear the k trannies like to grenade after a lot of power?

I havnt heard that.

What I am really looking for is a dyno chart of a k20 with a large snail on it. The largest I have seen was a t3 gt35R and it was at full spool @ 5500rpms I guess. It was making 640 something whp I think.

 

fukkit i say go with a gt42r

go big or go home right? he got the k20, might as well go with the goodiess

isnt there a guy from pacman whos got a k20 with a gt42r in it? or was that a 35r? either way tho.... some sickkk **** mos def. keep us posted.

Hehe. There are several turbos that I've configured that have put the GT42R to shame. (Which is a BOLD statement to say, I know.) I'm re developing w/ Borg-Warner a configuration that uses the same characteristics as the GT42R w/ 3psi of less boost, good to over 1600whp.

PM me if you'd like so a turbo can be configured to meet your needs than just blutting out sizes and housings with no background.

I'll say more when I get back from SEMA.

There is no possible way you can have a turbo produce 1600whp and provide even close to the same powerband as the GT42r. It simply will not happen. If it did, the material and design would be soooo far a head of the game that it would cost thousands of dollars. No chance a sub $2000 turbo can do it.

 

you really dont know who you are talking to do you?

he used to work for garrett designing turbos for a living.... he designed mine for me... 500whp on 93 octane at 18psi.

Shut the expletive up

Obviously you've never looked at a compressor map as you would clearly understand where I'm coming from. If what he is saying is true, everyone in the world would have a turbo that could spool at 3000rpm and hold full boost at perfect efficency to infinity. What he is suggesting isnt plausible. Not even close to plausible. Its so far from plausible that its near impossible. The day he produces a dyno sheet that shows a dyno of a GT42R vs this turbo he is "making", and the turbo he is making produces full boost roughly the same time as the GT42R and continues to make power till 1600whp is the day I'll buy into this. Until that day I'll take it for what it is, a bunch of crap.

Lets look at things from a numbers perspective. GT42R according to garrett is good for 500-1000hp. So since hes using maximum, lets use the GT42r's max. So we have a 1000hp and 1600hp. Now that means the Shodan turbo produces 1.6x the amount of power. Lets use turbos we know. Using the GT42r as the big turbo, 1000hp/1.6=625hp. 625hp is on the high side of a GT35r(600hp projected). So you are essentially telling me that a GT42R can produce a broader powerband than a GT35r? Do you see how improbable that is? Like I said, in order for this to be done you would need to be on the cutting edge of technology thus resulting in the turbo costing extrodinary amounts of money. There is no way it could cost the same $2000 a GT42r does. If you told me it cost $15k and told me it was made out of fancy material then maybe id buy into it. But thats only because shiney things catch my attention.

espically the "expletive" part!!!

 

before the bickering really gets going. If your goals aren't much beyond 650 or so you would probably be better off with a GT40R, unless of course you have goals of way more than that later. Plus you will definitely have full spool by 6k or pretty close to it.

Go check out Geoff from Full-Races dyno, or The Tea-Father's dyno after he switched to a GT40R. Yes they are on 2.0L b-series but it will give you an idea. Plus I figure if you are going to build a K you are probably sleeving and boring so your powerband will very likely be even better.

where in his post did he say full boost at 3k at efficiency forever? what he states is that the turbo exibits the same characteristics as the gt42r but makes the same power with less boost and can support more power... god you cant read

/yourself

 

stop the arguing and give the man some suggestions.

Genius reply. Do you understand what illustrating a point is? He is essentially claiming the impossible. Hes saying that the turbo will flow tons of air with no loss of powerband in the lower end. Like i said, go look at a GT35r vs GT42r compressor map. It will clearly illustrate my point on how improbable it is to have a compressor wheel essentially flow 1.6x the amount of air without having conciderable losses in efficency at lower flow rates. If he found a wheel like this, we would all have turbos as i described above. If you cannot understand what I'm saying go take your average of 12 posts a day and take them else where and let the big boys talk. I know honda-tech is notorious for sticking up for their friends and such but I'm sure shodan is a big boy and can make his own arguement on why he made the claims he did. He doesnt need you to make ridiculously ignorant posts. Also I should note this isnt bickering. This is called constructively or destructively discussing concepts. When someone makes a claim like he made you cant just say "oh wow, that sounds great!" Thats why for 2+ years everyone thought EL manifolds spooled the turbo faster than a log manifold. No one bothered to openly say, "hey, that doesnt make sense. do you have any proof of that?" You MUST question what is going on to have a sense of awareness so you are an educated consumer.

The one thing valuable the Shodan said and I 100% agree is find someone that can actually read a compressor map and understands a turbo is only PART of a SYSTEM and have them work with you to make choices to have the SYSTEM work best. This picking component by component crap without any clue on how things work together is useless. Going on Honda-tech and asking what turbo you want is pointless because other parts need to be disucssed. For example if you planned on running a log manifold i would suggest a larger turbine wheel to attempt to displace more exhaust to reduce the exhaust manifold pressure in a last ditch attempt to increase exhaust scavenging. While if you planned on running a long runner EL manifold i would say run a smaller turbine wheel because a big problem with turbo setups is throttle control and with a smaller turbine wheel theoretically you can have a bit more throttle response to counter act the larger volume(lower EL pressure). System...just because one part seems to be right doesnt mean it will work well with the other parts chosen.

It is possible to increase the amount of air a wheel pushes by "tweaking" the blade angles. Now this is what I've read...with most compressor wheels being made of aluminum you can only tweak the design of the wheel up to a point. Apparently designing wheels with too extreme of an angle(s) increases the amount of stress if recieves, which leads to premature failure or even comrpessor wheel fragmentation. TheShodan mentioned he is working with Borg Warner. After a few minutes browsing around the BW forums I found that they have been conducting research and testing on titanium compressor wheels. Maybe this is what he has in mind for his redesigned turbos, I dunno. Titanium compressor wheels are slightly heavier then aluminum wheels currently being used, but they are a lot stronger. This added strength allows the titanium wheel to have a more aggressive fan blade angle. From my understanding exceding the compressors tip speed rating is what will cause it to fragment. And AFAIK the Ti wheels are able to withstand faster compressor tip speeds then the aluminum wheels. The faster the tip speed, the more air the turbo is pressurizing.

I learned quite a bit of stuff about compressor wheel design, trims and tip speed when I was trying to figure out how to swap wheels on my T04E. But a lot of that stuff about the titanium wheels I read on the Borg Warner home page. I only read over it briefly, but that's how I interpreted all that stuff. Hopefullly I understand it all correctly, if not I'm sure TheShodan will let us know.

thats good info right there

didntl know that the agressiveness on the fins could make a difference... let alone the material they use to make it with. very imformative.

 

all I know is you need to take the

"First in ga with a K swap"off your sig. Because your surely not the first.
