Hanhs Race Craft Super 20g???

[GSX99Ca]

I was looking into some turbo's and was curious who has the Super 20G from Hanhs Race Craft and if you would recommend the turbo and are happy with the results of power, or if i should just go w/the super 16G. I have a 99 GSX, and looking for the most power at the wheels, keeping my stock internals, i want it as a daily driver and with only 91octane gas (top pump gas in cali ).

This is more bolt on power than probably the 20g.

Hahn Super 20G is garbage in so many ways. If you could yank the turbine housing off it, and slap a Mitsubishi 7cm housing on it, it's awesome. But the turbine housing hahn uses makes the entire thing a useless POS. Uses a T3 flange that requires either a T3 manifold, OR a cheaply made spacer that leaks. A 10cm^2 housing that lags like a mofo, and horrible resale value make it one of the turds of turbo choice out there. Like I said, slap a Mitsu 7cm housing on it, and it's now a worthy turbo.

He about said everything i was going to.

I second that. I personally have this turbo and I wish I had the money to just buy a better turbo and throw this one in the garbage. The lag on this thing bites and the spacer plates is a PITA and needs 2 exh manifold gaskets. I should have done some research on the S20G but now I am stuck with it.

I also had the super 20g on my car, and it was a laggy sob, plus the top end was nothing to brag about....I'd rather go with a forced performance big t-28...which I think is the best pump gas turbo. It flows enough to put a car into the 11's and has awesome spool up......or you cann just rebuild the motor and buy a gt35r

 

[tramp]

which hahn super20g are we talking about ? .... they offer a few
tdo5 or 06 turbine ?
8 or 10cm housing ?
Seen mixed reviews from this turbo. Those "sucessful" with it seem to like it alot.... hmmmm.

95GST4G63 shoot me an email on your turbo/specs [email protected] thanks

They all pretty much suck since they all use the 10cm housing. That's what makes it such a dog.

my opinion is, its a great turbo. got me 117mph in the traps@25psi or so, lag wasnt a big deal. i think its actually a great turbo. the bigger housing is a plus in my opinion more top end. hell i hung with my friend when he had an agp l2r and he was running 120+ traps

I have had a S20G and I agree with DSM.

There are tons of reasons why the S20G is better. I will lista few.

1. Properly sized turbine housing will not cause boost creep.
2. Larger turbine housing will make MORE POWER.
3. Hahns kit comes with a oil line kit 02 housing and all nuts and bolts to make it work along with all gaskets.
4. MADE BY MITSU.
5. Internal WG THAT WORKS!!!

Compared to a Green setup (Approx 2K) it is a bargain and offers 90+% of the power ability. Buschur doesnt say a 20G is the best street turbo for nothing.


This turbo works well for anyone who knows how to set it up properly. How many threads on here have people not getting their 50trimsd to work right? Most of the time it is the USER not the turbo.

YOu are also FWD, which blows up the mph. Very difficult to base hp #'s according to a FWD mph. That same turbo on an AWD isn't running better than 112-113mph, which is easily within 16G range. How does a car that traps 117 keep up with a car that traps 120+??

Tort9320G on here has gone 11.057@124 on a 20G which is faster than any green or 50trim on DSMTIMES.ORG so keep the misinformation to a minumum.

1. The turbine housing has NOTHING to do with boost creep. It's the wastegate HOLE that makes the difference.
2. For the most part, it usually will, at the expense of more lag.
3. They need to supply them, because it won't bolt up to shit otherwise.
4. Uhh...Mitsubishi turbos are by far the most ancient and outdated turbos on the market.
5. Major selling point there.


Yes, a new Green setup will cost approx. that much. But last time I checked, there were no fast S20g users on the www.dsmtimes.org board. And yes, Buschur did say something about a 20G being great. Put a 25 deg. clip on your 20g's turbine wheel, stick it on a super light race car, drive the snot out of it, and you too can run good times. But, one thing you fail to realize, is that Buschur did NOT run a Hahn Super 20G when he ran those times. I wonder why???

1. A too small of a turbine will promote boost creep and REQUIRE AN OVERSIZED WG.
2. UNless your compressor is maxxed out it always will and even when it isnt your car will make more power at lower boost with a larger turbine housing as delta ratios go down.
3. It bolts up to a t3 manifold just fine. And with the lit they DO SUPPLY IT DOES BOLT UP so no problems there.
4. Your opinion and not a fact. Prove this somehow?
5. Well a working product is a selling point for many poeple and an internal gate saves a ton of money.

Bushur HAD to clip his turbine wheel to MAKE A HACK WORK. A 7cm housing doesnt flow enough to make good power. a 10CM housing on the other hand will flow enough. Also Buschur was trying to use a "bolt on" turbo. Who cares if it bolts on. By that logic no full garret setups are any good. Also Hahn went into the 9's at 140+mph on a S20G.

That is the misinformation. Also you want to talk about stripped out tin can race cars then talk about Curt Browns car. Add in a shot of N20 and there is 130mph as well. Also I saw Curt brown run NO IC because he uses N2O and still go 10's. Does that mean thats the way to do it?

There is more than one "20G" Tort isnt using a "hahn" so that really doesnt apply with the topic at hand.

Tort is using a TDO5H tubine wheel on a TDo6 20G compressor. That is the same turbo minus the larger housing which when we were oput to dinner I suggested that turbine and he may use it to get some more power from his car. Just because HAHN SELLS A 20G they do not make them, Mitsu does.

It's a buschur 20G, tdo5h w/a crazzy clip 25 degrees I believe.

1. When you say turbine, are you speaking about the wheel or the housing? I can get an 8cm housing to creep as well. Just don't port the wastegate hole.
2. That depends on the compressor wheel as well.
3. And not everyone wants to buy a T3 manifold. And the S20G adapter plates were NOTORIOUS for leaking.
4. Got any idea how long the Mitsubishi turbo wheels have been around?? 30+ years. All of the housings were designed for cheap production, not performance.
5. Yes, an internal gate DOES save money. But, for the serious performance enthusiast, an external gate is almost always a must.

The 7cm housing flows just fine. It's the TD05h turbine WHEEL that doesn't flow for shit. Funny how those FP Red's with the 7cm housing were making 500+whp. Clipping the wheel relieves some of the backpressure and increases top end. And your Hahn example, was Len Ayala, and his gutted neon. It went 10.55@139 on a S20g, with a LOT of nitrous.

http://www.moparmusclemagazine.com/featuredvehicles/20302/

The turbo got Len into the 11.30s; with the 100hp shot of juice Len is going solid 10.50s at nearly 140 mph.

I search, do you?

I was referring to the 117mph traps on the other guys car. That power level is about 112-113mph in an awd car. Curt didn't need any nitrous to run 130mph on his Green. Back then, he was running a FMIC.

The other reason you don't see any FP Green's in the 10's, is because people buy them to put on their STREET cars. Since they first came out, it was touted as the best street car turbo, best pump gas turbo, due to the 50 trim wheel. So these turbos were going into full weight, daily driven street cars.

I'm shooting to be the 2nd person in the 10's on this turbo. I've got a LOT of handicaps working against me tho. I've still got a full interior, I'm running a 160k mile stock shortblock, and I'm still using the stock ECU. I'm not very far off, but I will still be just as fast, if not faster, then any 20G in a car that's not strictly a track car.

117mph traps with a S20G, eh? Only 1mph less than my best trap on an Evo III 16G!

Well if you read FPs webite they say themselves that the 7cm housing is a hack and just because it is fast doesnt mean it is right.

I quote FP here:
These Hybrid FPGreen and FPRed turbos sacrificed efficiency in the name of compatibility while putting guys like Hill, Cokic, Blaha, Brown and others deep into the 10 and even 9 second region. These turbochargers retained the mass produced OEM turbine housing for ease of installation, but were packed with much larger TD06H turbine wheels to satisfy the ever increasing exhaust flow requirements of the high powered DSM. Hacked? Maybe- but they were freakin fast!


Now that is a true statement. Also I may have incorrectly remembered Hahns times but I also see it is still faster than Curt Brown went on a Green plus N20 so my point is still proven. That is also on a shittier 420A motor vs a 4G63.

[Batty200]

My whole point is not to argue Green vs S20G. My point is sooo many people trash this turbo based on heresay.

The turbo is a sound design and can make good power. It is inexpensive and it is easy to work with since there is no boost creep and it is internal gate. If you take your time and install it right it will work fine and not have any problems.

That is the point.

Also the records page doesnt specify use of N2O and I know Curt uses it so I doubt the Green record is without it.
