HRC Super 16g or FP 18g

[GstStang]

Earlier today I removed my small 16g turbo so I can try and port out the hot side a bit when to my surprise the exhaust wheel was broken off The last time I ran the car I had smoke shooting out the exhaust and oil flowing out the exhaust manifold and couldn't figure out why. Now I know This is the second time the shaft brakes on me so I'm done with this turbo I was only pushing 17psi. Well the two turbo's I have narrowed it down to are HAHN RACECRAFT SUPER 16G and FORCED PERFORMANCE 18G. I wanted to get the opinion from people who know and used these turbos. I will be using the car as a Daily Driver so I don't want alot of lag and I'm shooting for about 350 whp at high boost. I'm also a big fan on sleeper cars which is why I ended up with these two. Any feedback on these turbos would help with my desicion

I`ve been running the Hahn super 16G for 7 trouble free years. It spools up super quick, & holds boost up to redline. Their kits are complete, & installation is super easy . . .

So it spools up quick even with the 10cm exhaust housing? That one of my main concerns for daily driving. Do you have alot of mods? I only have the 1g block, hard piping, 510cc, and cat back.

 

[TALONTRAX]

I have several mods, too many to list. The Hahn super 16G is a great upgrade to even a stock 1G or 2G. My car was basically stock when I swapped it in.
Now I will see how it will run with a 6 bolt stroker . . .

why a 16g or 18g? why not a gt30r?

The super 16g is a nice turbo. I had that on my 1g when I lived in michigan. It was cheap, easy to install, no special manifold required, and did everything I needed it to do on a stock motor with a few bolts ons.

I've heard good things about the 18g, but they are not very popular. I dunno why

And you're right about the sleeper-ness of it. They both look like a stock turbo. get either of those turbos and a evo3 exhaust manifold, which looks stock, and tell everyone its all stock .

Why not an EvoIII16g?

Very similar in performance to those two I would think, and a well-proven fast spooler. Not to mention they are everywhere so probably a lot less expensive as well.

Just wondering

EDIT:

I think 18g/20gs are considered to be "in between" turbos, and thus not all that popular. It seems that most upgrades go 14b > 16g (Evo) > 50 trim > Boeing 747 turbine.

Just an observation

If your only planing on making around 350 horsepower then I'd be looking at the Evo III. Their OEM technology and last forever and they've been proven over and over to be good perfect for your goal, But if you think you might be wanting a little more power later on then I'd go with the FP 18g. If has some room for growth but isn't huge and still should spool nicely.

That sucks aboout your block TALONTRAX. At least you're doing what I like to do, If it breaks make it better and stronger!!!

I was thinking about the EVOIII Big16g but from what I've read they seem to top off at about 350hp, my guess being that is at the flywheel. I also don't want to kill the turbo. As I mentioned on my original post my small 16g broke at the shaft twice and I'm only pushing 17psi, I've heard max for them is about 20psi. I have also seen a couple flow charts for the Evo16g and from what I can tell it's compressor efficiency seems to drop pretty quick when pushing high boost. I want a turbo that still has room for more if i decide for MORE These two seem to fit all my needs.

I always say I just have a BOV with people that don't know about my car I am trying to keep my car as a sleeper not just ### I enjoy confusing people when they see a "stock" looking car leave them in the dust but also because in the area of Souther California I live in used to be the biggest hot spot for street racing so cops are kind of mean to us. We had raids almost every weekend so i stopped going. So far I have been pulled over for looking like a rice rocket racer 3 times in my Eclipse (I was still all stock so no tickets these times) and 0 times in my Mustang that i run with no mufflers

I run the HAHN Super16G and have been for 3 years now. It's been a trouble-free turbo the whole time. With that said, you will spend a considerable amount of money getting 350WHP out of it. Probably closer to 310-325WHP max.

But yes, it is a very nice "around town" turbo, spools fairly quick (20PSI @ 3100RPM) and holds steady to redline.

The one recommendation I would make with this turbo is to take a die-grinder/whatever to the adapter (turbo/exhaust) to make a smoother transition for airflow. It will make a drastic change to the characteristics of the turbo.

 

[KingAWD]

Im really liking this thread as i have been considering both the HRC 16G and FP18G as well.

 

[BringBackDSM]

Some guy just made 290whp at 14.5 psi on a maft and very few mods on a fp18g. That would sell me.

 

[AlaskanDsm]

When I was doing some research on the FP18G, I noticed that comparing to the E3B16G people began to notice a difference between the two turbos only after about 23PSI. and then anything higher the FP18 made a huge difference outflowing the E3 by 50cfm because of the new turbine they use. I have also heard they use old ported housings so its more like a true "sleeper". I don't know how these would compare to the HCR...

If you are looking for some FP 18g info, there was a decent thread on it a while back. http://www.dsmtuners.com/forums/bolt-tech/270140-evo-3-16g-vs-new-fp-18g.html

 

[daren_p]

For those goals, I would have to vote for the new FP18g. Shouldn't have too much trouble meeting your goal on a properly tuned car. But before you do anything, I'd be checking you oil supply & return lines. Snapping a 16g shaft isn't very common & to do it twice, I'd defently be checking my setup out. Guys put 16g through years of much more abuse then what you have & don't have issues.

HAHN RACECRAFT SUPER 16G or FORCED PERFORMANCE 18G

Hahn "Super 16G" = Small 16G with a 10cm2 T3 exhaust housing. What this amounts to is adding lag to a turbo that is limited to a 505cfm compressor wheel; plus you've already owned a Small 16G.

FP 18G = A turbo with a little more top end pull than a 16G but not as laggy as a 20G. Rated at 100cfm MORE than the Super 16G. Were you thinking about a TD05H version or the new 6SL2 model?

 

[BringBackDSM]

I was looking into getting the FP 18g as well and did some research and I found that the way that the FP 18g runs effectively is at a lowest psi of 23 or 22. Thats how they designed it I believe. Have to re-check their site. Possibly because of the slightly larger turbine wheel they put in? Also if you are looking for some FP 18g info There was a decent thread on it a while back. http://www.dsmtuners.com/forums/bolt-tech/270140-evo-3-16g-vs-new-fp-18g.html I haven't kept up since. So I decided that i would rather go with the EVO III for now. Also the FP 18G does flow like 50 cfm more than then evo III so I don't know how that would compare to the HRC you have.

I own this turbo and to say it does not perform at low boost levels is not accurate at all.. Im running 14 psi and it screams, a guy just dynoed 284whp at 14psi.

 

[AlaskanDsm]

Oh i wasn't saying that it wouldn't perform at lower boost levels. but that when owners would turn the boost from lets say 20-22 or 23, there was a really big difference. And I was also just stating that was the boost levels stated on the site...or at least once were stated. If someone accomplished that amount of horsepower, then even I think thats awesome! sorry if it sounded misleading.

 

[BringBackDSM]

I guess I misread. I get what your saying.

I bought a new oil supply line that comes from the oil pump from RoadRace. The first time the shaft broke was from the compressor side. I have no idea how. My oil pressure is around 100psi at high rpm's.

I'm looking into the 6SL2. I have read good things about both turbos so thats why I wanted the owners opinions. I'm guessing there will be more about the Super 16g because they have been around longer but I still want some input.

Since it is more efficient than a 16g at high boost does that mean it will have alot more lag? That is one of my main concerns, LAG either because of the 10cm2 exhaust housing(Super 16g) or better efficiency at high boost (FP 18g). I know the Evo 8 and 9 run 10cm2 exhaust housing and they have very little lag (I love my friends MR )but they also use larger injectors and their 4G63 is overall more efficient than ours.

 

[daren_p]

Can't compare the evo's turbine housing to our single scroll, its like compairing apples to oranges & will introduce alot more lag on our setups. Most owners/previous owners all tend to say the HRC Super 16g is much to laggy for the flow capabilities of the turbo. They never made much sense to me, power potential of a 16g turbo with the lag of a larger turbo. The 18g 6SL2 seems like a much better matched combo. A better flowing exhaust side vs your std 16g series mated to a larger/higher flowing compressor wheel.

it won't have "alot" more lag but if you buy the 6sl2 version ther will be a noticable lag difference because of the larger turbine wheel. all in all you said you might want to go crazier in the future well the 6sl2 looks like your best bet right now.

injectors make no difference in how fast the car spools, you usaully upgrade to bigger cause of lack of fuel flow for the higher boost numbers. now i don't know if you can use a evo turbo as a comparision cause of the difference in everything from manifold to compressor housing and especailly the exhaust housing itself. sure maybe both the hrc 16g and the evo 8 mr and up 16g have 10cm exhaust housings but the evo housing slenders down towards the turbine wheel the hrc housing bacially stays that big, my buddies hrc 20g with the 10 cm housing doesn't spool till 4...

edit: daren p said what i said while i still was making my post... me still being owned....

 

[FORMONTOYA]

Most owners/previous owners all tend to say the HRC Super 16g is much to laggy for the flow capabilities of the turbo.

I would hazard to guess that most of those owners/previous owners did NOT work on the adapter plate between the exhaust mani to turbo to better match the "square to round" to avoid any disruptions in the airflow. Taking the time with a die grinder/dremmel/whatever to contour this adapter properly WILL dramatically change the characteristic of this turbo...

you would be surprised in the difference a little grinding in the right places can make. I'm very happy with mine.

 

[HighBoostLaser]

i like my evo 3 16g!

 

[KingAWD]

Awesome Guys, So far i like the FP18G, especially with that income tax sale they have going on.....

he he he

 

[MountainDew]

Theres a couple 18g cars around here making some very impressive numbers.

 

[TALONTRAX]

+1 on the HRC adapter plate porting. A half hour of port & polish work on that plate made a H U G E improvement . . .
