Garrett G Series

[discopotato03]

It occurs to me that Garrett are taking a long time to bring larger versions of this G Series to the market .

Its time they got their finger out in my opinion and had a look at bringing out the next turbine size up in the G series .

Keep an eye on the end of year trade shows

Both vids are SR20 and both are in the USA soo.....but still better results than thought and certainly makes these an interesting one when comparing to gt and gtx frames.

Yeah they are clearly an improvement over the GTX series, though if you look at the most recent result added to the EFR thread of the EFR7163 on an SR20 it makes it seem like there is more catching up to do to get to EFR status - granted the 7163 is probably the best performer "per pound" of the EFR range.

I reading a few claims at various sites that Garrett may have the G30 on show at SEMA .

Anyone know anything about this ?

Yeah, I've been saying for a while that all the noises I heard suggested that they intended on releasing the rest of the range - and have certainly not heard anything to suggest that doesn't still apply.  There seems to be a fair likelyhood we'll see G-series "up to 1000hp", which presumably will mean up to around 90lb/min turbos.

I'm patiently waiting too, if they are going to take another year I will end up biting the bullet and getting a GTX3582 Gen 2

But from the testing done by Sasha the G-Series turbos look very impressive.

I was conflicted about it tbh, it looked much better than the out-going Garrett turbos however - if you compare his SR20 result with the SR20 result posted for an EFR7163 in the Borg Warner thread recently it leaves things looking like the G25-framed turbos may be overshadowed by an old dog.

BW EFR hands down are quite the performer - however their resilence to abuse isn't that high as many have experienced. So for me the Garrett brand (as much hate as it gets by certain people in SAU - not you, others) tends to be the best option not to mention I get better pricing for them too

In other news, still need to get my car running properly first and give Tao some data I promised him about 2 years ago LOL

I'll reserve judgement until the G30 and 35 are released and the market gets to test them . Garrett is obviously putting them up against the older GT versions and the market will soon know if they aren't much if any better .

I'm most interested in the G30 and how it goes response wise compared to the GT3076R/GTX3071R . I'd like to see a bit less inertia and a bit better wheel efficiencies , in other words same power as a GTX3071R with better spool .

I'm going to put my neck out here and say I'd bet a cheeseburger that if there is a "wheel size equivalent" of the GTX3071R that the G30 will not spool as well.  I think with a lot of turbos, ESPECIALLY the G-series you need to pay attention to the flow levels provided and compare response with other turbos which provide that amount of flow.   

I would view it that the flow efficiency "mm^2 for mm^2" is much higher, while the response "mm^2 for mm^2" is a bit worse.  If you want to compare a G-series with an equivalent GTX-series for response, compare the G25-660 with a GTX3076R - it'll be hard to get a much closer comparison between two completely different series of turbos.   If you want to compare the G30 with something to get a gauge of the response improvements, you should be comparing with a GTX35-series turbo.

That's how I view it, anyway.

Day one of SEMA and Garrett have unveiled the new G42 1200 and G42 1450 respectively with new turbine wheel and aero plus stainless steel turbine housing. These will be available in Australia next year, pricing is yet to be confirmed.

Those look pretty grunty but I'm quite disappointed that they are putting across the impression that the two G42 releases are the only new G-series being released at this time, it's really missing the mark of what people are looking for.

Borg Warner on the other hand have quite possibly nailed it

[discopotato03]

I agree , the people at Evom are saying that the G30 may be released in 2019 possibly at Sema .

I reckon they could have sold many more G30s than G42s but they obviously decided to cater to the drag fraternity .

bit the bullet and went with a g25-660 .92 external gate on the sti. ej25 on e85. will post dyno results when I have it on there. wont be till after xmas.

compared to a similarly rated efr that's in the shop, its nearly half the size. (don't know what efr exactly, but told its only rated to 750hp)

this replaced a twinscroll td05 20g setup. have to say with a very basic road tune to make it driveable and zerod wastegate duty. it starts to make boost earlier than the twinscroll setup. it also made 15psi by 3k rpm. again, zero duty and a very rough tune. to say im excited is an understatement. will report back when link is installed an tuned.

Well if the G30 is going to be how some here expect it to be then I can only hope there will be a G28 , or a least a G28 turbine option . Sort of like a 6758 wheel size wise but less bulky .

That's pretty much what the G25-660 is.... except with EFR7670 flow

[LaurelPWR]

Another SR20 result looking very strong and promising!
