some solid power all across the graph. On pump and 21psi to! impressive! i want to see how the 10cm housing will do topend wise

 

So do we! We are doing the test next week.

Very nice results. How would you feel about this turbo vs the 20gxt-r or the Dom3 xt-r? They all seem to spool up about the same time.

 

The 20G XT-R is a great turbo as well for sure.

The Dom3 doesn't spool near as quick, in our opinion that turbo is too big for a stock location configuration. Drive pressures are just too high. If you don't want to go with a rotated setup and you are dead set on a big turbo though, the big Blouchs are as good as it gets.

subscribed for the 10cm housing test!!

 

In son!

 

how does boost response and lag of the 1.5 compare to the 68HTA?

 

The HTA68 comes up just like stock, but won't make NEAR the power that the 1.5 will.

~Cicio

 

definitely settling for the 1.5 now! will wait for the 10cm housing test for a definite decision!

 

I do have a question about the 10cm Cicio.

What are you expecting spool wise from it? I know it will increase flow, but will any more lag come with that?

 

I think we are going to see more lag for sure.

My thoughts are that the 8cm housing is going to be perfect for pump gas, but if you want to turn the boost up on E85 or race gas that its going to run out of breath.

10cm for E 8cm for pump

BUT that is just a guess right now.

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.

Does the 20g car also run the invidia race monifold?

 

Dom 1.5 FTW!!

Imma stay tune for the 10cm housing test!

 

Indeed. I've been considering the 20gxt, but now this one looks awesome too.

Wow what a difference...

 

This is why I am going 1.5xt. So much better than the 20G series of turbos.... Thank you Topspeed for the dyno and write up test of the 1.5

 

UHHH OOHHHHH!!!!

SOMEONE HAS SOME E85 IN THE TANK :devil:

 

And a 10cm hotside?

 

Not yet...we want to turn the 8cm up on E and find where it falls off

let's see a youtube video posted!!!

No problem!

totally forgot to ask.... are you still running the stock clutch set?

Yes sir The E85 tune is probably gonna do it in.

^ i just ordered the 1.5 a few hours ago. thanks to RSD for the help!! :devil:

TS: IT'S ALL YOUR FAULT!!!!

 

LOL

Your welcome

You could have ordered it from me for the effort LOL

Enjoy it man

This turbo seems to be the best turbo option out there.

Its pretty darn awesome!!

Can't wait to turn it up!

I'm starting to think the same thing.

 

The 304 whp run on the stock turbo, I assume that was protuned stage 2?

 

Yes sir!

 

Wow so this thing keeps up with the power delivery of a VF43 protuned... That's really impressive

 

Here is the graph compared against the 20gxt. Both cars are dual avcs sti's with the exact same setup.. header, downpipe, tmic, etc.. Both cars were run on E85 at 25psi avg. You can see from the graph the dom1.5 spools much faster giving you over 70ft/lbs of tq more down low.

Red run is the Dom 1.5 with 8cm housing
Blue run is the 20gxt with 10cm housing

We were having some fueling issues, the car needs a FPR with that high flow Aeromotive pump so were weren't able to pull 4th gear on the dyno....just in case your wondering what the difference in spool is from the original pump gas graph....thats why.

~Cicio

 

incredible! that graph is madness! :tup:

 

Oh yea that turbo is happening on my car.

At my pro-tune appointment I will be discussing this with you Cicio.

 

I'm following this thread closely because I want this turbo, but you guys have to keep the graphs the same. The first graph shows SAE correction and the second shows STD correction. I hope there is no dyno funny business going on.

 

There is no trickery going on at all. This graph was a comparison, I just exported it in whatever setting it was on at the time.

I will be happy to show you it in SAE.

Thats the nice thing about a dynojet...there is NO WAY to play with numbers. There are two or three correction factors, and the end user can always see them...its great.

Awesome! Looking forward to it.

Peak hp is a little too far left for my liking on e85. Looks like the 8cm housing is running out of steam, looks like the 10 will be required at those levels. The 8 might still work out well for a real conservative e85 tune though, good stuff. This turbo is looking like a winner imo.

I assume once you get the 10cm housing you will do a 20 and 25 psi tune on it as well to give the full picture? That is really the only decision atm to be made imo.

I agree that on E85 the 10cm is going to make better/broader power. I will be happy to do a 20 and 25 PSI tune to show you guys. We have a completely booked week, so its probably going to be the end of the week before I can get the car back on the dyno with the new hotside.
