Pumaspeed X-37 Hybrid Turbo Thread

I like how the first thing to do was jump to the conclusion that it was the "build quality". Nobody, including WeTheNorth, knows that the installer didn't touch them. The installer could of said he didn't but do we really know? If he put on new crush washers and it fixed the problem it sounds to me that he took them off of backed the off and re-torqued them damaging the crush washer it was originally shipped with.

The plugs and crush washers are brand new when shipped from Pumaspeed, when the turbo arrives here I make sure every bolt and plug is tightened before shipping because most of the time I'm installing an actuator before shipping. During that time I put a wrench or allen key on everything to make sure it is tight, I have yet to come across a turbo that has has anything loose. As an installer myself of many, many turbo kits and engines in high horsepower cars I always go everyone else's work, maybe that was the case for this installer or maybe it wasn't in the end I know that everything is tight when shipping but anything can happen.

You weren't expecting a leak, I apologize for that. Sometimes things don't go as initially expected, if everything went 100% according to advertised then some people might not have problems selling their turbos or turbo kits. Forcing them to resort to being a crybaby with their slow brethren in a competing products thread. That is slow has multiple meanings too. That is just my thought on it, but what do I know I just shut down these whiners every time their mothers let them out of their basement. To this day the turbo, which I don't manufacturer, does everything it is advertised it can provide. All numbers that were initially mentioned were hit by multiple customers, not just by one dude. Again not once has there been an exaggeration of performance on this product. So you are getting everything you paid for, though it might take some time in the end you are getting the best sub-300hp turbo for the Fiesta ST.

Now, on the subject of it taking time, some are going to be bummed. However some are going to be jumping with joy that they finally might be relevant again. The next batch of X-37 turbos will be the last batch for awhile. We need to catch up on cores, get everything sorted, and get stock. So we have one allocation left on the last batch that is already ordered and in progress. Once that shipment is here and gone it will be a few months before they will be sold again. The plan is to get them on hand and not take any orders until they are ready to ship. That was the original plan but when you get 25 orders in 2 weeks and only have 20 cores in circulation it's hard to have everything done in a speedy fashion especially when those cores in circulation take awhile to get back from customers.

We will be testing a X37+ for the Fiesta ST in the next month or 2, but they will not go into production until there are yet again proven performance benefits and factual number claims. It is very possible that the X37+ will not end up going in production at all, there is a limit to how much air you can flow through a factory frame turbo before you have to recast the housings. So, we will test theory and post results when available. Until then any emails regarding the X37+ and further testing will be forwarded to this post.

Finally everything is working in sync,no pun intended.i haven't heard the infamous whistle but I am running a stock intake , one thing that I will have to attend to is my boomba vta adapter. It now sounds like shit, not that it ever sounded that great but it sounds brutal with the X-37.

And as many have said before me, base tune and this thing feels awesome. Can't wait to have my 94oct buttoned up and then on to e30 , just for when you might need it down the road:)

Starting from what year? 69 Ford country squire station wagons will be easy pickings.
Wow really? I didn't think it'd be that fast! Lol.

I mean the typical cars you see on the road... Camaro ss, mustang gt, brz/frs, STIs, charger/challenger, civic si, focus st, etc. I was gonna say corvette but I think even pulling on a stock C5 would be pushing it lol.

You can get a rough idea on power to weight ratios. A 300hp fiesta weighing around 2650, you're at 8.83:1 lb:hp which puts you in pretty high, mustang gts are around 10.6,
So stock muscle car killer...
You'd be beating mustangs that weigh 3700- 2015gt weighs 3700-3800, and have around 425whp.

lol, BRZ/FRS and Si's are in the same tier as a stock FiST. Should already be pulling on them by the time you're in stage 1.

ASSUMING YOUR going against a stock Si. I went up against to NA modded Si's and had my lunch handed to me on a Stage 3 E-30 Tune+ tuned car. Don't sleep on the K20/K24 cars. Easily the best 4 cylinder NA engine out there. Makes a ton of power NA. I raced a friend from work multiple times. He has I/H/E, a Hondata tune and some pulleys and everytime would pull on my car. If it's stock, yeah no problem, but if it aint stock don't be surprised. Now with an X-37, you shouldn't have any problem with an Si. Mustang Gt's and Camaro SS, I don't know. Think you might be neck and neck if they are stock and your car is tuned to the balls running at least E-30. Right now with my Cyborg on 93 I can pull on an Infinity g37 and 3.8 liter Hyundai Genesis coupe.

Aren't the 4door models 2790 ? I've always used that in V dyno. Plus your body weight.. Ratio ends up higher

Mine weighed 2740 full and you remove the rear seat and you're at 2650. I don't count people too much since they aren't that much and both people have to drive... Raises the ratio slightly, still raises theirs too.

Mine was corner balanced in May and with a full tank it weighed 2563 lbs. Take Vdyno for what you will and with the X37 on E30 I am showing 281 peak whp and 276 lbs peak wtrq. I weigh 215 lbs, and the power to weight ratio comes out looking good.

I haven't run up against any cars since the X37 was put on, but I did pull on a FoST on the hwy once back when I was stock turbo and on E30.

When cooler temps come this fall I am going to take mine to Royal Purple Raceway outside of Houston and run it for trap speed in the 1/4. I don't care about the time (not interested in launching from a dig) and I will be curious to see the speed.

Mustang Gt is 435 HP (crank not wheel). Big difference.

Notice I say beating stock muscle cars... Wheel hp on a stock coyote is 340-350whp, weighing 3700+, Those come out on average as 10.6:1, and you'll be able to beat one that has in the 425WHP region. Which is 8.5:1,

Yeah so about a 10:1 power to weight ratio. So the fiesta would need about 275whp to match it pretty evenly.

I've removed rear seat a few times. No way it weighs 90lbs.. More like 35-40 the most!

Sorry, but you are not beating a Coyote Mustang that is putting down 425WHP. That translates to Shelby 350 GT HP, and those run 12.2-12.5 1/4 mile times. an X-37 FiST is not hitting those quarter mile times, 0-60 times would probaby be more disparate. A properly tuned X-37 FiST can touch high 12 sec 1/4 mile times which is no slouch, but lets not make it into more than it is. You should be beating 370 Z Nismo, Genesis coupe 3.8l, Stock Sti, Stock Evo, Possibly Stock Mustang GT or tie, Bmw 335, Audi S4. Mind you these would all have to be stock

Those are comparing quarter mile times, I'm referring to roll races where traction is not a limiting factor...
To go on the fact that you don't think the rear seats weigh much? I weighed 2740 with rear seats and full tank, weighed 2600 even without seats and half tank. Nothing else changed.
So, if you want me to spell out my math again on power to weigh ratios, which don't include traction as a factor, the you will be able to keep up with a 425 wheel horsepower mustang gt that is stock weight of 3700-3800lbs. So 3750/425=8.823- that's the mustang.
Fiestas can see 2650lbs easy, so
2650/300=8.83 that's what the x37 is capable of guys.
That's dead even power to weight and that means a lot when traction isn't the limiting factor. You comparing a gt350 that's rwd, and can pull a very respectable 60', yeah it'll run a faster 1/4 time but a roll race will be dead even...

A 300hp car that weighs 2650lbs is a around a low 12second car. Whether that power gets put down determines that. Of course that's on an online calculator- a couple actually- but as someone else stated, he wants to run for mph not et because mph will give you an idea of what else you'll be against on a roll race. Expecting these cars to trap 110-113

Ok.. THAT I can believe. The rear seat + jack and spare, you're talking 50-60lbs the most. The front seat is a good 40-50lbs, maybe more. So half a tank of gas you say? That's about 6 gallons, yeah I would believe that's another 50lbs or so.

I've gutted my car and ran with 1/4 tank. Thing was super light. You could tell a drastic difference. I'm not disagreeing with what you said, besides saying you lost 90lbs by taking the rear seats out. All the seats and half tank of gas, sounds about right
