Pumaspeed X-37 Hybrid Turbo Thread

[masonsturbos]

Ive had both and the x37 feels way better. My gtx2860 was very linear in its power and felt most of its power at around 6300-6500, while the x37 feels real torque down low and follows through with some top with it. I would destroy my old setup, unless i was running maybe some aux with the gtx, then maybe the outcome would be different.

What power were you at on the 2680???

 

[masonsturbos]

For what it's worth, you had an ATP kit. so yeah, the X37 would destroy any of their kits. the dhm 2860 kit is pretty versatile. not thread jacking or fan boying. It can spool fast, and can make power. but just letting [MENTION=1579]masonsturbos[/MENTION] know so it's not immediately biased. and the info is accurate.

See, people praise the dhm kit, it uses the same turbo and has a tubular manifold... It spools 300-500 rpm sooner, if that, it makes similar power. I've seen an atp 2680 kit dyno 308, I see more dhm kits dyno 280-290ish.

Never got around to dyno it i got rid of it really quick. But just in comparison, with the same sti I have posted on my channel I would pull about 2 maybe 3 cars on my gtx. That was on 91oct, i was never able to run e85 with it.

ok, so first off, I am by no means praising his kit. and I am not trying to ruffle feathers. I have 331whp/309wtq on the DHM EFR kit on 92 oct pump gas no meth no aux fuel, stock fuel system(on adams tune) I have another where a local shop did a dyno day tune for business and did it free and they got ~315ish. I chose it over the 2560/2860 because I knew it would make more power. You can only go so far as the FUEL will let you. its not persay the hp per the kit you use. Our fuel system is the next thing that suffers after the turbo is replaced. the 2560(gt290r kit) without aux fuel is making the same numbers-ish as the x37, the 2860(GT360r kit) is breaking the 300 whp mark on pump fuel. where the x37 needs aux fuel to do so. I'm not hating the x37, and im not hating the DHM kit, what I am doing is this: when you put each turbo on level playing fields. say 91 oct, the X37 and GT290r(gt2560) kit are about the same hp. step up to the gt360r kit(GTX2860) and it gets 300whp-ish on pump 91 where the x37 makes that WITH aux fuel/meth. so you have to level the playing field before you go poking at stuff.

I have seen those, it seems like the best dhm kit to go with. Im assuming thats with some aux fuel?

if I were to go back I would choose it or the one I have now. but its according to the exhaust side your choose. suffer up top but have awesome spool with the .54ar, or get the .63 and have more top end and less spool. it spools decently. nothing like the x37 does however. just makes more power on PUMP gas. that's it's advantage.

 

[masonsturbos]

That's some crazy power on 92oct... Have a dyno sheet?

 

[TempeST]

I do, I have about 7-10. But for sakes of not going off topic and not posting Vdyno's/Dynos of things not x37 so it get confused heres my build thread so you can go check out what you need.

I saw some that looked like Vdyno, we all know from [MENTION=4033]Ish[/MENTION] that Vdyno numbers don't speak truth

And I agree with you. but as per my previous post I was on a dyno day on the same dyno in my videos, where the car made 195/255 stock and now made 315/300 on the same dyno dynamics. I do not have a dyno sheet for that but give me two weeks and I'll have what you want. VDyno sheets are all over this thread as well. and where I agree they can be fudged, and don't mean much, You get a very good idea of the power curve. and when you try different combinations rather than only one and getting high numbers, when you tend to have different combinations and they are all between 6hp of each other I feel it is accurate, especially considering that a not well known tuner made 315 with my car and adam makes 331 on the same exact kit, but better tuning strategies I feel it is accurate. I am not here to boast. and I did not even mean for this to be pushed toward me and my setup, although I brought it up. I was only trying to set you in the right direction when you claimed the X37 makes the same power as the 2860. and where you are correct it CAN. when using the same fuel system and same fuel it won't. GTX 91 vs X37 91=2860 wins, GTX 91 vs X37 e30 they are similar.

The X37 is a great turbo. it really is. but it's not best for everyone. I was only giving you the info so that this wasn't a completely biased thread. if this isn't understood, that's fine. fwiw, I'm extrememly happy with my setup, and I would never trade it for an X37 because I would lose a Huge amount of power because I do not have access to E30. 92 vs 92 my kit wins, and is why I chose it. trust me, Adam and I went back and forth on this for quite sometime. nearly three or four months. and my ultimate decision was to make more power for a certain power to weight than the X37 could provide. but again my personal preference.

I wish I had taken more of pictures of the bolts as the threads on those bolts were cross threaded, tech says they coolant was pouring out and he had to tighten the bolts and it helped but didn't stop the leak. Hopefully we can fix it without sending it back. Disappointed in the workmanship for sure.

If you need more bolts/plugs, or your bearing housing is damaged beyond a reliable repair, then you can send me the center section and I have a spare one I can fix up for you. I'll do it for shop cost with no profit.... Assuming you need help and no one else will take care of it... Well... Shop cost and actual shipping.

Stop. Just stop. Well reasoned explanations have no place on a car message board .

I just think it's great there are so many options.

Thanks very much for that offer! It got resolved but we had to change some bolts and crappy crush washers. I really do appreciate many people who have reached out to me and have helped me [MENTION=4033]Ish[/MENTION] [MENTION=952]frankiefiesta[/MENTION] and a BIG thank you to a local company [MENTION=4300]Alex@Stratified[/MENTION] for the quick response and helping me solve the issue. Thank you all

Now let's see what this thing can do;-)

That's really awesome that some other companies and forum members stepped up and help out. Glad to hear your good again

Glad your issue was resolved. Too bad you got bad customer service. Shipping took what? 2 months? Then when the turbo was assembled poorly you were basically told figure it out.

I've been telling whoever will listen to purchase the turbo directly from pumaspeed

Do we know for a fact the installer didn't cross thread the bolts?

I've had the X37 on my car for two months and 1,000 miles. Those 1,000 miles are mostly driven at extra legal speeds, and I don't baby my car once it's warm.

The car seems to be getting quicker, and I'm pretty sure that can't be right. I drove it yesterday and was especially aggressive doing a couple of WOT pulls to 120. The last pull had me slipping the tires through second, some slip in to 3rd, and then quickly the car was at 120 and eager to pull well past that. One of these days I'm going to take it to 140 just to see how quickly it will get there, but not until the temps are lower. I live in a rural area south of Houston and there are some great isolated long stretches of flat road that I can see down for miles. I don't drive "fast" if others are on the road.

Most of the time I get used to the power pretty fast after I add a power mod, but with how I have my FiST set up currently it's one of the 1st times with all the cars that I've owned over the years where I feel that the power is perfect for the car. I'm returning a VERY respectable 23 mpg E30 average, and instead of researching how to make more power my focus is on reducing weight, increasing airflow to the engine, and upgrading supporting components such as brakes, oil cooler, and who knows where it will end?

My current tires are 215/40/17 W rated on 17x7.5 wheels. I have a tire tread gauge from my discount tire days in college that reads 8/32's of tread taken from the center off the fronts. I rotated the rears a few weeks ago and they have 6/32 of tread left. That's a nice amount of remaining tread to be spinning as easily as they spin on power in the lower gears, and I'm concerned that the 15x8 6 UL's on 205/50's might spin even easier once I swap out my hubs to a 4-100 bolt pattern.

I am changing out my oil at 7k and will send it to Blacksone for an analysis and to see how the engine is holding up to 26.78 lbs peak boost at 84F outside ambient and 70% humidity while running E30. I love the X37 and how quickly the speed builds and the cool noises that the turbo makes. This FiST is now officially my favorite car/toy that I have ever owned.

Rhino- That accord was the fastest car outta the lot I'm sure? That's some good feedback in your post. I was hoping to have those feelings about this car after I had some mods done to it. I've been holding off because it's just too hot in Vegas for me to want to even install anything, much less run it hard, but I see you're in Houston giving it a wee thrashing.

That's a question for [MENTION=4339]WeTheNorth[/MENTION] to answer. My guess is no. Why would his installer even touch them? The only person who may have touched them was pumaspeed, the people building the turbo. Obviously the situation should've been handled better by the man selling the turbo. Everyone involved is lucky that the leak was able to be fixed.

 

[WeTheNorth]

Nope, the installer did not touch those bolts. We just had to put a pair of oem bolts off my stock turbo on and some better crush washers to solve the issue. I've put more than a 100 miles on it and have sent my logs into to Adam and car seeks leak free.
