He's using known results

omg gud idea kno ne 1 selling 1?

On 98 I don't think the smaller units will get close. The median figure I have seem for an SS2 on a reliable roller dyno is 270, hence why I think a G3 is a good option for someone intent on getting closer to 300 with minimal mods/98.

Hypergear G3

This is the same dyno as my car was tuned on, Lith. Per our private discussions that should clear the air a little.

Hmm, I don't think its that bad man. A stock OP6 is pretty laggy on a 20, so I don't anticipate a highflow to be much better. Not to say that 4800rpm is great spool but I do think its on par.

4800rpm from an OP6 highflow on an RB20 is fairly reasonable I believe, also making the right power for a bolt on for an RB20. If Yavuz thinks he can dial it down another 500rpm and not lose any power that would make for a pretty good bolt on result. Props.

Haha cool. I thought it read ok

Sorry, literary error. I mean that GTR is to RB25 as SR is to CA etc. I hope that reads well enough for most. I hate inaccurate information.

If you are prepared to build the motor but want to try and get away without you can always try. Whilst the motor is good for the power in described trim you should bear in mind that the longevity of the motor is also largely dependent on condition and the life up to that point. Much like tests on SR20s, lots of people kill them at 200kw and then others have tested them to 400. Be it myself I would stay within the known constraints but would boost it till it blows. However I would be prepared to replace the motor should it grenade. GL and keep up posted

Yeah GTR boxes are cheaper. Though, one could buy a blown RB25 box and then retro the GTR internals. IIRC they share the same internals much the same as RB20/SR20/CA18 do.

For reference I also tried a 12cm variant and found it opened up the bottleneck from a .63 Garrett as it should have. Agreed to be good value.

So far my GTX has proved very promising on my pissy 2L, so I can only imagine that the 3067 would be an even better alternative for those aiming at the 300kw marker. Am glad Garrett has at least some redeeming options available.. I have been all but wowed from some of the larger GTX variants, as I feel many of the others have been. I may recommend a 3067 to a friend with an upcoming build. I would be pitching it with a Kando 10cm housing

This is one of the things I have always feared with the PFC and hand controller, it leaves the opportunity for the tuner to not back up the tune as he does the whole thing using the hand controller. I would be hoping that they actually backed up your tune on a PC. Contact the tuner and ask. If they only tuned it via the hand controller that is honestly quite irresponsible and I would raise it with them. GL

LOL one cannot plough the field without a good tractor. BBBbbbbraaaaaaaaapp

Why not stick to the SR? Hypergear has a good bolt on unit right now, you should check it out.

He's referring to your comp housing.

15kw top end gain but fairly drastic midrange improvement, very nice.

He cropped the larger turbine until it was the maximum size the T28 housing could accept. Lith, 260 is a very reasonable result. The two I know of (known from face to face interaction) failed to exceed 220kw.

This is in reference to 2L motors in single IWG configuration. I believe that the resultant geometry of the enlarged housing (its made for TD05H wheel) is not adequate for the 61mm TD06SL2 and the character sucks. Both parties I know of have struggled to exceed much over the 200kw mark. A change of turbos has resulted in far superior results, one of them switching back to a Kando TD05H-18G (T518Z). I think the mentioned 9 blade TD05H combined with the 68HTA wheel could be mighty promising at your level, but am not sure the cost exercise would yield benefits over pre-fabed Kando billet 16G units.

XKALABA just be awares that I have known 2 people so far to have poor results from TD06SL2 T25 IWG housings, and have known none to be successful. The housings work FINE for TD05H application as proven by a few of us, however I personally ONLY have negative results for the same housing used with a TD06SL2 core. Food for thought

Kando 10cm T3 housing is $200 delivered. Send it to Stao and $150 later it will suit your 73HTA unit.

Each to their own. When you two are done enjoying the smooth rolls of the calm ocean I'll be waiting by the finish line, yawning.

I have long wondered about the use of an FP DSM item in a Kando housing. I contacted FP many times asking for a T3 variant but they refused. Told me to build a custom manifold. I also quizzed them on the origins of their 67mm wheel and if it was a TD06H, they denied using a H wheel and would only tell me that it was a 'wheel of their own'. Quite a PITA if you ask me but I do not doubt that a Kando housing could be made to suit without much effort. Someone SHOULD try it on some sort of 2.5L....... COUGH ARTZ

I don't think its fair to talk about twin scroll in light of gains over open, not at all. I believe it is more so a different result than it is an improvement as such. The twin scroll will definitely bring boost on earlier but will also roll on/off smoother and give an overall more linear feel. Not everyone is into that, Owen's GTX is a good example. He and I had many a PM about that and it was honestly determined that he just wasn't happy with the twin scroll efforts. He much preferred the brute delivery of the open .82 In my own experience I am much the same. Not worried about smooth roll ons and how early it starts to make 'some' power. I am more concerned about how easily accessible power is and how hard it will pull at that point. For that I would say a good open housing will definitely deliver.
