I agree completely. And I have debated that g30. But I haven’t found many results on it. I know the gtx line is proven to take abuse and hold up. So I’m leaning more towards a gtx.
You're not wrong. Most often than not, when a new turbo gen or design comes out, there can never be an apples to apples comparison. Comparing the GTX to G-Series is about as easy as comparing a G-Series to EFR. Knowing the nuances of the engine design and how best it interacts with a turbocharger is going to net best power. Unfortunately, that just takes time, and lots of resources. This is why a 3076 makes great power on a Honda, EVO, etc... but not so much on a Suby. You have to look at compressor maps and know the Subaru is going to make nowhere near 'ideal', and they LOVE large turbine housings and big A/R.
that sounds a bit laggy for my goals. It would only give me about 2k of powerband (not raising rev likit). But they seem to be great turbos. I really want to see what the g30-770 does. On paper that seems like it would be good but you never know.I have really enjoyed my G30-900 so far - I did a data log and I am hitting peak boost at ~4820 rpm btw (forgot to post it this weekend for you sorry!). The place that did my tune also had 2 GD body race cars (I think they do hill climb mostly) one is on the GTX3582 gen 1 was at 539whp/542tq @30psi, and the other is on the G35-900 that was at 640whp/540 @28psi while my G30-900 was 569whp/473 tq @26psi (all on E85) and my Killer B headers helped too
The other cars have a larger fuel system than I do plus no AC with shorter piping and different manifolds and probably spool just a little faster than I do, as well as fully stripped and cages compared to mine (full interior with AC!) so they are not apples to apples necessarily but just more data for you to chew on.
I was waffling between a 3076, 3576 when I was planning my build but ended up with the G30-900 which feels like it is maybe between the 3576 and 3582 though I have no hard data to prove that, just butt dyno readings.
I’m anxiously awaiting seeing this. The g30-770 is the one I have my eye on vs the gtx3576 and 3076 gen2s.
@Karlot I'm assuming you saw this post👆
I have seen those. But the dyno plots are small and very hard for me to read. But at those boost levels if I’m reading it right it seems super similar to what the 3076r gen 2 would do.
Yeah the g30-770 does look to be a very nice turbo. Honestly when I do get one it’ll be between the gtx3076/3576 and the g30-770 lol.
I am not a veteran driver but I absolutely agree that seat time is the most important thing. And I planned on staying in street class anyway. I just figured I’d get what I really want as as time goes on slowly crank up the boost (one of my best friends is my tuner, so I wouldn’t have to pay for a bunch of tunes to do so). But regardless yes I understand what you’re saying and agree that it’s not a necessity, but seat time sure is
You’re not wrong about that haha. I currently have a 20g so it’s still pretty darn fun to track. I just find myself wishing I had more haha. Granted I do need more seat time and to this point i haven’t done anything but improve. My last trackcross day I improved each and every lap.Pretty sure it's more fun to be the fast guy with the small turbo than the slow guy with the big one
thank you. And I’m sure it will bring smiles haha. I’m definitely on the slower side but I haven’t had an event yet where I’m not either faster every lap or can’t identify why I went slower. Typically that’s when I either brake too early or slide lolololololol. These cars are so much fun to track anything will bring the smiles.
did you ever get the results of this
