I think you don't understand what I am trying to say, I suggest you do some googling.

I dont need to google anything. I am the one here that made record numbers on -5 turbos. I specifically asked YOU what is the restriction? What is the back pressure ratio on -5's? What is the back pressure ratio change when externally gated? What specifically is the advantage to externally gating these turbos on this engine?

Your motor will breathe, externally gate anything before the collector and you'll make more power.

It's not rocket science.

And congrats on your epic record achievements because it's a US dyno. I'm sure my corolla would make as much power as your setup too if it were on some inflated US dyno :)

Also, calm your farm.

congrats you managed to make 800 field mice power with -5s on an American dyno

That is assuming that anything after the collector is in fact a restriction... You have no data showing that it is or that an externally gated setup will benefit this specific application.

I would also like to point out that everyone seams to be laying the burden of proof on me. Has anyone here specifically dyno'd on a dynojet to say that it reads high?

And still hasnt seen the strip....

Car will see the strip. Just got the clutch sorted out. Now working on a tire rub issue.

If you love playing statistics wars, I heard the stock market is a fabulous place for that :)

What do statistics have to do with definitive measured data?

FYI - you still have not answered my question.

hint: its because you dont have the information to answer said question.

It is well known that dynojet number's are ALOT higher than dyno dynamics or mainline dynos here in Oz.

Run it up on a mustang dyno that will give us a far closer number.

Im sorry but on a stock head and stock cooler etc that your car has that power simply isn't possible!

Dynojets are around 15% higher than our dynos on average.

Don't need any data, proof is in the pudding.. piggaz's turbos were over worked, glowed probably redder than the sun, boost bled down up top.

I don't need to work for NASA to tell you that the housings are too small.

Anyhow, a couple of Nissan SR20s would pull a premium one week before race wars

Look, I was letting this thread sit till we ran the car at the track except I keep getting multiple emails a day with you jack holes cluttering up the tread. I am not stating anything until I run at the track.

So we are looking for high 130mph?

no, need at least 140mph.. Maatouks can do it with less powererererer.

Ok, so the turbos glowed and the boost dropped off...

Turbos glowing - excessive egt.... why?

Boost falls off - Compressor cant keep up (out of flow). Not related to exhaust housing restriction. If anything boost would remain at targeted level because the gases cant escape the engine quickly enough.

    • Just as a thought, if it's in neutral, thats your drive line disconnect, not the clutch. Clutch slip at the dyno with pedal fully out, is actually adding a second disconnect. So it's not a clutch issue if you're in neutral. Just a bit of friction dragging the output around while in the air.
    • The HG high flow is excellent, and costs about the $$ you're talking about. But it, and probably every other highflow, uses a diffeent core than the original turo, and the original Hitatchi core is quite long. So, I think it is inevitable that there is likely no such thing as a highflow that just "bolts on" with no other effort required. And the same is likely true for HG's outright replacement "bolt on" turbos (the ATR things). And the same is likely true for anything similar from elsewhere. I have no idea if the cheap Chinese/Taiwanese complete turbos from eBay/Temu/etc are as bolt on as they claim. I mean, they claim the bolt onto the NAs as well as the turbos, and we know that can't be "bolt on". But it wouldn't matter because I'm not buying a $169 4 psi turbo for anything other than a paddock basher.
    • Bummer...yeah i "need" something to "ease" up the work and for my driving it would be enough.    Iam counting the tune "without" turbo. I do not mean "cheap" like something from Temu around 200 USD, "Cheap" is something around 1000 USD? 
    • Starter motors used to use the weight of metal (magnets) to provide torque. Now they use (more) current instead. This. It's completely normal.
    • So thing that had me stumped, but I think is OK....is that when it was up in the air, in neutral I had it running to bleed to coolant while I put the wheels back on. I noticed the rears were turning (slowly) which I'd never seen before 20250928_163512.mp4     Because there had been an issue with clutch slip due to pedal adjustment on the dyno, I assumed there was still and issue so spent some quality time upside down under the dash adjusting the pedal....but no matter what I did the wheels still turned in neutral. Even disconnected the master cylinder to pedal rod and same. In despair, I even removed the clutch slave so there was no chance of any preload causing it.....still happened. So either: 1. Something is not right in the bellhousing, or 2. Its a thing sometimes with cold, thick gearbox oil Internet says it might be 2, I hope so!
