Default TopSpeed Motorsports | DOM 1.5 TESTING COMPLETE!!!

Today we finished the testing on our 2011 STI with the Blouch Dom 1.5 Turbo. We have done countless Blouch 20g XT builds here at TopSpeed, but no one had ventured out to try the ball bearing Dom 1.5. We were honestly floored with the results!

What we look for in a stock location turbo is something that we can keep drive pressures down on, still spools quickly. A lot of the bigger stock location turbos do not appeal to use because of the high drive pressures and laggy nature. We feel that you have to give up so much power curve most of the time that its better to stay with either the smaller stock location, or just bite the bullet and go rotated.

This turbo however surprised us! We are very happy with the curve, power, spool and top end performance. This test was done using an 8cm hotside, however we will be swapping to the 10cm to see how much power band we give up. I would recommend this turbo to anyone looking for great power, and a huge broad power band!

GRAPH OVERLAID WITH THE STOCK TURBO PLOT



**EDIT
Here is an overlay of the Dom1.5 8cm & a 20gXT 10cm

This will be a better compairison once we do the 10cm testing on the Dom1.5, but this will give you guys an idea.

As you can see the 10cm barely outflows the 8cm up top with the 1.5, while the 8cm 1.5 kills it until 6k RPM

More to come guys.

Wow. I assume that is "stock stage 2" tuned, right? Looks like you give up very little on the bottom end for some very healthy gains. Good stuff....

I updated the first post with boost and fuel...21PSI peak on 93oct pump gas...sorry I had to rush to get the thread done earlier and forgot.

I will post a boost graph tomorrow from the logs for you guys when I get to the shop.

Turbo is SICK on the street! Spool is so close to stock, yet there is SO much more power up top.

Great Numbers! Just curious why the stock air box on the stage 2 and dom 1.5 testing? Seen some good info on updading the stock box so far.

Looks like some awesome results. Which I find to be expected with Topspeed. I have a friend with a 20gXT tuned by topspeed, still running the stock airbox and making over 400whp on E85.

Looks impressive. Were these pulls done in the same gear as the stock turbo baseline? How does this compare to the 20g XT?

Thanks

We find the stock box to be more consistant than a CAI when under 400 whp. You may be able to put on an aftermarket intake on the dyno and see a few more HP, but then go sit in some traffic when its 90 degrees out and see what happens. The stock box is not a restriction point under 400whp so we leave it be.

Good question Ed, we ensured that they were done in the same gear as it will change the spool with the extra load in 4th vs. third. I have tones of 20g XT graphs, but honestly 90% of them are on E85, so its not a fair comparison. I'm going to dig through my records and try to find one for you guys today.

I'd been looking at an AMS 750R set up on pump gas to get around those numbers and now your telling me I can do it with a bolt on turbo and injectors. I have on 08sti with Invidia Race header and TBE. Sounds great but almost too good to be true!

What are stock numbers on this dyno? I can't see the graph as my ISP blocks the image hosting server you use.

Thanks!

Depends on whether the baseline run included the inlet, headers, UP and TBE. the OP doesn't specify conditions for the baseline other than "stock turbo".

Clarification would be nice.

Were the ID1000's maxed out? How well would they do with E85 on this setup?

If you are going to go AMS I would suggest the Garrett based kits VS the precision.

But yes...this turbo would make 400whp with a TMIC/FMIC I am quite confident.

Thanks!
So sorry about that...I should have made it more clear.

The "baseline" was the car fully tuned with all of the same mods except the turbo. It has an equal length Invidia race header which is why the torque numbers are amazing on stock turbo.

See above..fully protuned full bolt ons, not stock baseline.

No they weren't even close to being maxed out....and this setup would EAT UP some E85.

Don't ignore the truth

The 20g is a great turbo though.

Thanks for the response, I assume by "EAT UP" you mean they would love it, which is great news for me

Awesome!!! I looked for days for a dyno graph on this turbo before I bought it to no avail. I'm running it on my freshly forged motor w/ headwork but am still breaking her in. I was expecting closer to 350whp so these numbers are quite a surprise! If you wanna check in on my build in a few weeks you can watch my journal here - http://www.3gwrx.com/forum/index.php...;topicseen#new and I'll be posting dyno numbers as soon as she's broken in and tuned. My mods are quite a bit more extensive though so I think ill be putting down a bit more power. I'm excited to see the differences between te 8cm and 10cm! Subscribed!
