Well as promised I hit up the dyno today before class, very quickly.

Here are the specs:

It was a simple street tune on the dsmlink, stock timing and rich a/f between 10.5-11:1

I am still blowing through a 3" high flow cat that passes smog and a 3" exhuast. The turbo hangs on a SBR evo manifold and evo3 o2 housing. The turbo is the bullseye t04b vtrim. The boost controller is the profec b. I am STILL on 550's and 190 pump. 3" dejon intake, JR 25x7x3" IC and his 2.5" piping. 1g throttle body. Stock bottom end, stock head, stock intake manifold, stock cams. Its a 99 GST with 80,000 miles and a fresh clutch.

I live in CALI so we only get piss water 91 octane. This was a street tune, straight from the street, onto the rollers. We had to strap it down twice as much as regular cause my allignment is SOO bad ever since i swapped ball joints without doing an alignment yet, . It barely stayed on. The runs were made at 11psi and at 18psi. It spikes slightly to about 19 but falls to about 18 or so because I still have the bullseye Low pressure actuator.

All in all I was very happy given the setup. This car will pass smog, run on 91 octane and not knock like silly. The most knock I was seeing on the link was less than 1/2*

Here are the results. I will keep the race gas tunes to myself when I am done with them as I still run on the streets and dont want to scare away the spies who know where I roam

My race gas tunes will be done on 22psi, 112 octane and appropriate timing, you do the math.





Hope to see more dynoes of these things, I am very happy with it so far.

Dave @ bullseye - this should get you started and should hopefully spark new interest in this turbo. For those of you who want to see the race setup, meet me on the streets

was 298 made on 10 or 18 psi?

look at the dyno, 10psi was 232whp, 18psi was 298whp

Run 7 was on 11psi, the other 2 are on 18psi

I need a new boost gauge, because I have a chean sunpro $15 gauge that was the gauge and bracket,


My dsmlink logged 20psi spike but fell off to 14-15psi by redline So i dont know which one to believe

I have a DEFI boost gauge coming in the mail, that should be more accurate.

FOr those who want to start talking about how 16g's make 300whp+ go ahead and come to cali, pass smog, run 91 octane, jump on the dyno from the street, and make that figure for me at 18psi, i will pay you $100, it just wont happen, trust me, I tried

What kind of timing were you getting up through the RPM's?

Wow, nice numbers. I just got done reading his site because of someone's post about turbos. It seems like a quality turbo and does not require a person to buy a new manifold, or O2 housing, if I read correctly. This turbo looks very interesting to me, I'm sure with my current setup if I put this turbo on it would put me in the 11's quickly. How does it spool, how do you like the way it spools etc...

a stock eclipse will see a rise to about 16*, which is what i saw, so a normal timing curve, except i saw about 17* towards redline

On race gas I will be adding another 5-7* which will be a HUGE difference, plus more boost

I was happy to see my a/f DEAD on in the low 11's and barely dipping into the 10's by redline

Looks like JR's FMIC works out just fine unlike what some people thought because of its size, my logger showed a consistent 68-70* intake temps, this was with only a small HOUSE FAN in front of the car, he doesnt have the dynojet specific turbine fans yet....so much for that misconception Outside temps were about 65, inside were about 68* so thats pretty damn good with 4 runs back to back

The spool is ok, I was told some turboes came cliped some didnt, i imagine mine was clipped because some people are claiming 15psi just over 3000rpm,l i dont see 15psi until about 3500-3600rpm, i wish it was earlier, but oh well, just gotta brake boost when i go from a roll

My roomates stage 3 srt4 spools INSTANTLY, like 2500rpm, , yet stilll makes power to redline and runs 340whp, amazing what newer technology does


EDIT: these numbers might be more impressive then they look because my dsmlink logged a falling boost down to 15psi, my cheap boost gauge didnt, and seeeing as how i havent maxed out my 550's like others do on this turbo at 18-20psi, it just may be running less boost then i thought, which is great for me, thats even better

Awesome, sorry you didn't hit your targeted 300whp, so close! I think with 93 octane and running consistent boost you'd be better off...but I don't see why your profecb would allow it to be spiking to 20 and dropping to 15? That's weird, I'd like to know which is correct.

correction: its not the profec letting it drop, its the lower Presure actuator

i was the only one to get the low pressure actuator from bullseye, just to try out, and its only good to about 20psi but it may start falling off towards redline, so i will have dave swap out the high pressure with me


the good thing about the loower pressure one is i can get boost down to 10psi and go WOT in 1st gear with control instead of smokin the tires

as far as my targeted 300whp on pump, its only a matter of time, i still need a few things(actuator, real boost gauge, bigger injectors, for all i know i could be running less boost, as my logger shows and as my injector duty cycle proves since im only at 91% and on this turbo, by now, i should be maxed out at this boost)

As far as my ultimate goal on racegas, dont think i've posted all my information yet

More results coming next week as i head down south to the Carbon by design meet for srt4 guys and they are going to have a dyno shootout there as well

And you did it on this FMIC?

Pretty darn strong.

About the wheels being clipped i asked dave this and all of the to4b versions come with a clipped wheel. The first generation to4b came with a clipped of about 5-6 degrees. The third generation which most of us have come clipped 8 degrees. As for your spooling time thats right where its supposed to be. People with cams and such like me spool at 4,000. Good dyno results but it kinda sucks you were on 91 octane. I'll be dynoing on 93 and see what kind of boost i will reach before it knocks. Thank god for dsmlink .

no..most of the ebay ones are prefabs chinese ones that arent really a good intercooler

i got JR's IC, he still sells them through ebay, but also has his own website and phone number and all, and he is a coolass guy, he always helped me out, worked with me, did what i wanted and made me some badass 2.5" powedercoated black IC pipes as well that fit perfectly

JR builds them himself, in oregon, and he uses modine cores which are awesome, and mine is a new hybrid style, its like bar/plate inside, and fin outside, its very nice

the numbers look great, hopefully this puts the naysayers to rest. With cams, 650's head studs, head gasket, better fuel and a little more boost and you got 350whp. Glad you made it on the Dyno nazar.

, i wont need cams to get that, i promise you this u'd be amazed how this car LOVES race gas and timing

I think cams will make a world of difference in your car. Your hp is SOO flat up top to me it seems like you have a bottle neck some where which is what is capping your hp at this moment.

IMHO I like the 546/547 web cam street grinds or else the crower stage III's for a more agressive cam. I have these in my 2G and it idles almost better then my 1G with the webs in it. They have crazy lift!!

Good luck on your goals.

Good numbers, 18psi thats not bad expecially through a cat. But i wouldnt say its anything to be proud of? I passed emisions here in MO then went to the track and trapped 107 on pump gas with a cat at 20psi. And the car made ~290awhp in this setup. Sorry to rain on your parade, i dont mean to be negative just to let you know that other cars can do that too and dont come off so cocky right away?

Did you try 19 or 20 psi since you were getting almost no knock you should have tried to turn the boost up some and make that 300fwhp.

not trying to be cocky at all, i just sifted through those 25 pages of battle about the t3/04b vs 16g and all, and i had both...

I thought these numbers were pretty good to start with. Here in cali, passing smog is a whole different story, also, try making big numbers on 91 octane and you will also think 300whp is pretty good, ...its not easy

For example, 94 octane vs 91 octane is HUGE

WHen i add a gallon of xylene to my car along with 6 gallons of gas, i get about 94 octane and i can do SOOO much more then i can on 91 octane, i can add 2-3* of timing, run 3-4psi more, and hte car just feels totally different, and this isnt even race gas

I am not trying to be cocky at all, just happy with the results for a baseline, my ultimate goal is 350whp with this turbo

I didnt try that boost for 2 reason: I am still on 550s, and my wastegate actuator wouldnt let me go much higher even with the profec B, i might need the high pressure actuator from bullseye

I have also never had a 300whp FWD , this is my first, and I am happy with it, and it keeps amazing me that a 2.0L 4cyl can really be this strong.

its all good, And my 16g wont hold boost either but that doenst mean more boost wont make more power It will drop down to about 18psi by redline no matter what boost i run.

Those are good baselines no question, just seemed like you were cocky with the hole 100 dollar thing and well that made me type my thing. I have 93 here, and thats what i run. And your right 91 vs 93 can be a factor but you really cant say for sure. 91 and getting almost no knock at 18psi. Try 20psi and if it gets knock you know the gas might be a factor. But good job let us know what race gas does too the numbers. i only gained ~12awhp from 20psi and pump to ~25psi and race. But after cams that changed.

Id recomend cams but that might make passing smog a little bit more challenging.

and does the turbo at 18 PSI give you a grab the seat of your pants pull?

Congratulations on those numbers.
I can't wait to see another pull with higher pressure in the mix.


I run 18psi daily on my 60 trim, and every so often I raise it a tad higher.
And let me tell you, there is a definite seat of the pants difference between 18 and 21 psi.


And like you, I need cams

the difference here is 20 to 25psi on a 16g is different, because youre stepping out of the efficiency range
this is why when i raised boost from 11-18, i gained about 70hp, which is still about 10whp per 1psi

So going from 18psi to 25psi on this turbo should theoretically get about 50-70whp, no so on a 16g because its already pushing at 18psi.

Next week I will do 22psi on race gas and cat bypass

25psi max, then falling to 18psi is what mine was doing

Also from 20psi to 26 i gained oh 32awhp with my cams

Hmmm not bad for a baseline. Since there was all the talk about the evo vs t04b I made a couple spread sheets with some dyno pulls that were done with the evo & the one that you did with the t04b, just so I could see the difference. From what I saw the hp & torque graphs almost looked the same for both turbo's with the to4b just slightly showing abit more lag and slightly more hp. From the charts I would say the evo is just as good as the t04b but the evo dyno pulls were taken at 19 psi where yours were only taken at 18 psi and if you dropped to 15 then I would say there is some potential there for 40 or so more whp. Looking forward to seeing your next set of pulls. Anyone else going to dyno this thing?

just a quick update

i was reading the other threads on these turbos and bullseye, and 20gs, and so on and here is more though

a good friend of mine here in town, had a 95gst with a 20g, and all supporting mods, big fmic, no cat, etc...

He dynoed 282whp at 22psi on that turbo

I dynoed 298whp on my vtrim, 18psi, pump gas, through a cat, and stock airbox

I am VERY happy with these results, this weekend i am installing a water/meth injection kit


Look for 25psi dynoes next week, on race gas and meth injection, bypassing the cat, with a cone filter....im looking for at least 350whp

I am fairly confident about this turbo and i bought the extra warranty, so as long as bullseye doesnt go out of business or something, i am not worried as they will replace my turbo if anything happens to it.

I like it because it fits much better then 50trims, it spools nicely and i got a great deal and good dyno results so far. Old school or not, its a good turbo

How many lbs/min is that turbo supposed to flow? Got a map?
