Dose Pipe Sutututu

I did, I wrote something about the Spool v1 gears (black anodised) being munched up when I spent the entire skid pan at the limiter. However the gears were placed into stock used N1 oil pump with over 200k km on the clock. Got in touch with Spool and they said those years aren't theirs? Interesting because I bought it from their damn site!! Pretty perplexed anyhow, bought v2 of the gears, also with a brand new N1 pump and they're still on the car now. Has been through 3 hours of dyno, 1x skid pan, a big drive to Singleton and back to Western Sydney.

LOL you always get so worked up with euro cars haha... BTW the older E36 and E46 M3s are slowly creeping up in value, I'm thinking of getting one.

That M4 sounding like a bargain now compared to a R32 GT-R ?

I stand corrected However "Don Mega" spec should be at the very least an AI tank with zero welds. https://aftermarketindustries.com.au/surge-tanks-swirl-pots/bosch-surge-tanks/Aftermarket Industries SPR1200 Version 2.0 Billet Triple Fuel Pump Surge Tank designed for the following fuel pump Bosch BR540

If it is "Don Mega" or "NASA" then you shouldn't be using a welded up surge tank However, I am ready for the challenge of who will break their gearbox first at Wakefield.

That's terrible advice, get it on a dyno and load hold it at a fixed RPM or road speed.

I personally don't have any data however if you follow Benny from Benchmark, he pretty much straps like for like turbos onto an 4G63T and they come on earlier when compared to a RB26. Remember the big stroke of the 4G63T at 88mm versus the pussy stroke of the RB26 at 73.7mm, thus you need to rev the living daylights out of a RB where as you don't with a 4G63T.

But it's not, even a non MIVEC 4G63T will spool up the same size turbo on a RB26 earlier.

The Old ATR43SS2 (Circa 2016) was a bit more urgent to drive, however it's a bit harder to compare as the motor had stock cams and power would nose over about the 6500rpm mark. Where as the GTX3576R Gen 2 with generic Poncams just wants to keep going. Even at 7500rpm (at lower boost) the power was still climbing to the rev limiter (8000rpm). On the street you would easily get 1bar of positive pressure by 4200rpm and you would happily stretch its legs to 8000rpm giving you a nice 4000rpm to wind out. Tuning wise, because the torque is quite flat, timing was quite flat too and the VE table also was quite flat, making tuning somewhat much easier than a motor that produces a mountain style torque curve. Should be good to use the power this weekend at the track, it's been 3 years since I've seen the track.

This is the best spot.

Replace with a RB25 boat anchor ol

BMW F80 M3 or M4 /thread

As a doctor @dr phil you would be very familiar with data and facts haha. Not like this Paleo Pete Evans ? I'll pull some logs off the car at Wakefield, be good to see how my oil pressure, fuel pressure, oil and fuel temps behave on the track. There's a 6.5L baffled ASR sump in there too.

I would go Evo 9 for these reasons: Faster Safer Handles better Can make it go around a track fast cheaper & easier than a GT-R Doesn't have cooling issues like a Skyline But I still own a Skyline, because I am an idiot.

Surprisingly mid to high 40s only. I didn't export the logs this time for the S15, was only a quick 1 hour tune to full send

14 degrees mid range, sweeping up to 19 up top. Tried to pop in a few more, but wasn't worth it, as each degree only net an extra 1~2kWs.

Not really, now I have just wasted more money lol.. more money that could have been saved for a BMW lol Scored a free track day, my mate paid for it since I tuned his car. Speaking of which, that S15 I tuned a while back with fuelling issues came back with a solid 274kW at 1.7bar boost on a GTX2860R Gen 2. It's making numbers of the older GTX2867R Gen 1 but at least 400~500rpm earlier.

Very streetable, you get about 1bar of boost by 4100rpm and the power is quite linear. If you look at the faint dotted lines when I took a photo of the dyno screen you can see that torque is relatively flat too. As the car was going on the dyno, I borrowed a pair of old AD08R which were rock hard (didn't want to destroy my semis), on the way home was pretty funny. Roll into 3rd and the tyres would blaze LOL. I'm heading to Wakefield this Sunday, should be a good shakedown!

Time for an update to the shit box, this time with bigger and badder dose pipe for you dose bitches. Nearly 3 years in the making too 407kW @ 2bar -> 1.8bar on E85. Mainline AWD dyno, with 16kph/sec ramp rate. Mods: Garrett GTX3576R Gen 2 Garrett T3 1.01 divided rear housing Turbosmart Gen V 50mm Sinco T3 twinscroll, single gate manifold (pulses split to the gate seat) 3.5" Turbo back with 5" body Venom Cat, 2x Mufflers Generic built RB25DET NEO motor Spool billet oil pump gears Tomei 260/9.15 Poncams 80lb Valve Springs & Ti Retainers by Performance Springs HDi Hybrid 76mm eBay FMIC (holding back the power) With high IATs air density is dropping, thus boost is bleeding off as well with small DC corrections on the boost DC table. I did order a Plazmaman Pro cooler but it didn't arrive on time. IAT peaked at 57 degrees C in a dyno room with an ambient temp of 19 degrees C. From the data, reducing the IAT will improve the boost control up top, get more air into the motor and will yield the results I'm after. Once the FMIC comes, I'll be back for round 2. Special Thanks to: Alex at Birrong Automotive for allowing me to use his dyno Adam at Weldspeed for the fabrication work Yez Racing for supplying most of the parts Data, etc. available in my build thread here: Sorry for the lack of derived RPM, I forgot to set it up, in the Analyse screen it shows you true RPM vs. Power vs. Torque. Log during run: IAT post run:

There's a slight difference as I run a cat converter in the car.. yes it has a cat If a car runs a cat I never rely on the rear tailpipe sniffer for tuning, it's there as just a guide. I always insist running a wideband before the cat/cat area to get a proper representation of how the motor is behaving. Not to mention, if there are small exhaust leaks, that will introduce foreign air from a venturi.

I'm running Bosch 1480cc at 3 bar (often called 1550cc, or 1650cc depending on who you talk to). At the back I have 2x Wallahbro 460s in an AI SPR400 tank, and a DW200 lift pump. Both 460s are PWM and DC is ramped as boost increases. No silly potato staging, to avoid spikes.

I believe from the data, the boost behaviour is due to the increase in IATs. I do have an IAT correction table which adds an extra 1% every 10 degrees the IAT climbs (probably not enough). And yes, that's how the Kebabtech works. You have a base ignition table and you add a correction/compensation based on ethanol. What you see in that table is when E85 = 100%. There's another table where you can adjust the blend too. If you look at my dashboard view, second column 2nd row that's the actual timing, and 2nd column 3rd row is the base timing. I'm confident I'll get it to that unicorn 600hp mark for internet bragging rights ?

I rather go put on a Kando turbo (optioned with ball bearing & billet comp wheel) off eBay than a used HKS2535 turbo.

It took me 1.5 years to tune the car, if I put back stock cams then go and tune it again we would be all dead lol. We both can hypothesise it could come on earlier however make less power.
