BNR S3 DYNO NUMBERS???

[Speed3KG]

I will post my dyno once im done with my freek tune. Cuz i will be on just 92 octane. I dont wanna deal with the other stuff. Keep it simple looking to get as close to 350whp as i can.

[Smelson]

Here is my most recent vdyno. I have a gt2871r so it's pretty similar to the s3. This is on 93 only.

FREEKTUNE FTW!

Something must be seriously wrong with my car because on 93 pump gas I'm only making 300whp on a gtx2867 cf1.01 at 22psi and 13.5 timing at redline/11.5* at 6k. This is in Florida at sea level. You're making 50+whp more than me. I'm also tuned by freek. I'll post up a recent VD as soon as I get home. I think it was 294whp/335wtq at 78 degrees and semi high humidity today.

What other mods do you have? I have a 3.5" intake, 3" single exit catless exhaust and a custom exhaust manifold.

Mods are in my sig. I'm still on the stock exhaust manifold and I have the stock catback with a catted CPE downpipe. Here's a recent graph and log.

Yea sorry no sigs on Tapatalk. I'm just flowing a lot more air. Nothing is wrong with your car.

Unless you are running really good 93+ octane pump gas, ethanol or methanol with aggressive timing, you're not making those numbers.

Otherwise you are running the default cf in virtual dyno for those numbers which is wrong.

[06yellowroush]

Oh ok I didn't change the cf in the vdyno. What does it need to be set to?

[dale_gribble]

For a mazdaspeed3, set the correction factor to 1.01 for results that have repeatedly been proven to mirror many various dyno results.

Smelson -

i have a question on mounting the GT2871R. there was a single mount point on the old turbo but the ATP GT2871R I have there are no mounting points.

How did you mount yours and does it just float between the manifold and downpipe?

[Lex]

ATP turbos do not attach to the block like the OEM or BNR turbos. Some people have adapted the bracket to just brace against the bottom of the turbo.

On the OEM exhaust manifold I wouldn't worry. On tubular ones they may crack over time.

[Justin@Freektune]

If you get a high quality manifold like full race or Cpe you should have no cracking issues by not using a support bracket.

Mine is just "floating".

Here are my most recent VD's on 93 SAE corrected in 75-80 degree weather, 118* BATs. I'm tuned by FREEK and I'm planning on either meth or e85 once I get a TR8. 12.5* at 6,500 RPMs, car runs a pretty consistent 4.9 60-100.

i made simular to those numbers with almost the same mods on 93 octane...mods were cobb intake/tih, hpfp, corksport test pipe, res delete, freektuned.

[dale_gribble]

Damn, here I am having a problem pushing into 300WHP on BNRS3/brand new motor with full intake/exhaust flow mods on 91 pump gas. @ 20psi, we are already seeing 1-2kr from 5500+ with ~9 degrees advance @ 6500.

I have no clue how @boostdmazda3; put down this on California pump gas alone:

Im at 21 psi with 12 degrees of timing made 334whp 370tq running at 100% injector duty cycle.

I would like to know this myself ...

[twenty5psi]

ACN91 is just terrible fuel. Though some cars do seem more octane sensitive then others, maybe try to wring out some lower BATs with TIGs/TB coolant bypass. Remember that 300whp on an MS6 is different than 300whp on an MS3.

[dale_gribble]

I am actually kind of shocked this is about as far as the BNR + 91 goes for my base tune. Unless someone has really good pump gas, my suggestion at this time would be to keep k04 and get WMI or E85 + tune instead and not dump $1200 on a turbo that really doesn't do a whole lot on 91 pump gas. That's a lot of money for not a lot of return IMO.

If you have really good 93, well there's an argument for that.

[Speed3KG]

Okay here is an update. I made 365/360 on 92 octane fully bolted gtx2867 . Almost done with this meth tune and I hit the dyno the 7th.

[twenty5psi]

The GT28 turbine I think is a tad small for this motor to make big power on pump gas, it only gets worse when crammed inside the K04 hotside.

Are you saying that @ ~16psi of boost (at a given max timing, for me its around 12.5*) on the stocker that the extra S3's ability to hold the extra 4psi to redline (and I'm assuming less timing) is basically producing the same power? Is the WMI just that effective at making the fire breath of that K04 tolerable to enough timing to make up for less boost?

[dale_gribble]

I am just debating on whether it's worth it to try a 2 heat range colder plug and see if I can run a little more or if this is the end of the road. As it is right now, I am running the NGK 1 heat range colder (6510).

If the rule of thumb is 'for every 75-100hp increase, go a step colder' @ ~300WHP, that is about an 80hp pickup, so based on that, maybe a 2 step colder would help this setup.

That's basically what I'm saying. WMI/E85 allow you to bump redline timing up north of 15-16 degrees (I think my last setup with k04 was up to ~18 degrees advance at redline). That extra 4-5 degrees of advance is worth a good amount of power. On my k04, WMI with 5gph nozzle at 50/50 = easy 30WHP pickup. My old tired engine + k04 + WMI = 290-300WHP.

So, yes, what I am saying is if I am knock limited on my BNR S3 to ~8-9 degrees/20psi, the k04 with WMI/E85 with the extra 4-5+ degrees of advance at 16 psi boost will result in at least the same amount of power if not more.

Now when the BNR gets WMI/E85, then it's a totally different story.

I think I was also limited to 300awhp with the BNR on 91. Despite that, it still is a turbo that won't smoke, holds power to redline without blowing hot air, and has room for more power.

Not sure who goes BNR S3 for more power without the intention of running e85 or meth though...

[dale_gribble]

I decided I am going to bring my spark plug gap tighter first with the NGK 6510s (7 heat range). It's interesting, a lot of import tuners from evos to turbo hondas to turbod small blocks have .028" as the high limit for plug gap. .022"-.025" gaps seem to be very common across the board when approaching 20psi+. I am running .028.

Common symptoms of too large of gap are misfires, break up,kr and detonation. I am going to drop my plug gap down to .024 and see if the kr goes away.

[dale_gribble]

Ok, so the 6510s are the right heat range (1 step colder). The discoloration on the ground strap was right on the apex of the bend with just 1 of the plug threads a smooth black.

Dropping the gap to .024 did seem to have a slightly positive effect. Kr was a bit lower (.35-1.05) compared to this morning (1-2.5). BATs/IATs were about the same on the same tank of gas. Still, I think 8 degrees at 6500 is about it. That puts the car right around 300whp, VD cf1.01.

[JgamB]

I'd say go alt fuel with a mid-turbo, or don't waste your time and money. My last Vdyno was 360/352 with 80F BATs that climbed to ~115 by 108mph, so even though I'm able to throw more high RPM boost and timing at it with 25% Eth and 98% IDCs, I'm neutering my performance by being lazy finishing my meth kit.

[scubasteve711]

Thanks for documenting this process as you go Dale... Cant express how much I appreciate your posts and insight

[tokoam]

In Florida here on 93 I made 294whp on 93 and just about 350 on e85 here is my results.E85/93 compare to just 93

[dale_gribble]

Here you guys go, my current BNR tune on new engine vs. Stratified tuned k04 on old engine on crappy 91 pump gas, SAE corrected. The BNR setup on 91 is still getting some kr (1-1.5) north of 5k so ignition/advance and boost needs to come down a bit north of 5500.

I thought it was pretty cool how the curves aligned from two different motors, 1.5 years apart with 2 different turbos. I love this graph.

Pump gas for pump gas, the BNR still outflows the k04 and holds power to redline. You can see how the torque peak hit is about 500RPM later and the BNR setup holds the power curve a lot flatter north of 5k. This graph perfectly illustrates what the BNR does for a k04 car.

[Lex]

Great comparison. I just can't wait to get some wmi in the mix as I am sure you feel the same.

[tokoam]

my numbers look so weak just did a pull in 4th got 278 tell me im not crazy

[dale_gribble]

My #s suck too, I am going to be 280-290whp with FULL flow mods on 91CALI pump gas only. Once we attempt over 20psi with ignition tapering up to 8.5 @ 6,500, boom, KR. Car is probably going to land ~19psi flat from 3500+ and ignition tapering up to around 8 degrees and that's it.

What is your ign adv at redline?

Don't you guys have good 93 down in FL?

[tokoam]

10 deg I though we had decent 93 but I guess not.Feel free yo check my log its posted .

[dale_gribble]

Everything looks ok, though flow #s look low. What are mods on car, year of car, miles on car?
