Not an EVO engine (EJ257) but it's one datapoint that might be of use to anyone considering PTE6062 gen2:

0.63 AR vband PTE5858 (dotted) vs 0.82AR vband PTE6062gen2:



0.82 AR vband PTE6266gen1 (dotted) vs 0.82AR vband PTE6062gen2:




0.82 AR vband PTE6466 (dotted) vs 0.82AR vband PTE6062gen2:



Orange line is boost in kPa.
6466 curve had ported head. Others stock head.
Add 14% to whp for dynojet SAE.
Add 18% to whp for dynojet STD.
Race fuel in all tests.
1.2bar wastegate spring in all tests.
75-85% wastegate duty cycle in all tests.
Yes I was expecting faster spool from 6062. Will try 0.63AR next time.

Thanks for sharing this results.
So, this comparison shows that the 6062 gen2 spools at least 300rpm slower than the 6266 gen1.
And it spools about the same as a 6466 gen2...

I have a hard time to believe this, and my first thought is that there is a problem on the 6062 dyno (boost leak, exhaust leak...)

I had my PTE 6062 Evo VIII tuned by Vlad at National speed in Wilmington, NC earlier today. The engine was rebuilt by Central NC Speedshop (CNC) at the end of 2015. I was pleased to see Vlad squeeze out 478whp/391tq @ 25psi on 93 octane.

Where is the link to this build?

Hey guys, I'm not an Evo guy, but I'm doing some research on the Gen 2 6062 for my MKIV supra. I currently have a Gen 1 6266, but would like more spool. I've been looking at the comparison of 6062 vs the 6266 and 6466. I think there is something wrong with the 6062 car.

Here is a comparison of a Gen1 6266 vs Gen2 6266. The spool is ever so slighly later on the gen2 6266, i just can't understand how the Gen2 6062 would spool SLOWER

I have 6262 and spool isn't bad at all

Another datapoint for PTE6062 gen2. This time an EVO with 4G64 block, 100mm crankshaft running VP C16. Not perfect since start rpm not identical between tests, but generally reflects results from STI testing earlier.

So, it spools slower than the 6266 gen 1? And even though it outspoole the 6466, the 6466 powerband is a 100-200rpm ahead of it after 4700.


Also, is that on pump gas, race, or E85? The power signs off super early. None of those powerbands look all that great. Basically 5k-7500...

The runs were not started at the same rpm point, hence why the difference in spool between the two seems little to none, if the runs were done exactly the same there should be enough spool time in favor of the 6062 against the 6266 gen 1/2 and the 6466. On the other hand if the 6062 was on an .82 a/r with the runs done exactly the same it would be interesting to see the spool curve. Powerwise though the 6062 would make around 20-25whp or so more on the bigger hotside.


I agree the powerbands are too narrow, to have and be able to feel a powerful setup you need to have at least 3,5K powerband rpm.

Ah, I didn't notice the start points. Starting the 6062 sooner would also help broaden the powerband a bit. Not sure it would enough though.

Evo8cy

Taking into consideration that the 60mm inducer wheel should be lighter with better aero and to account the fact that the turbine wheel is the same as the 6262 and smaller than the 6266 unit, depending of course on how much difference there is between the two rpm start points , the difference in spool must be 500+rpm between 6062 and 6262 and 1000rpm+ between 6062 and 6266, and 1300rpm+ between 6062 and 6466, which in my book the 6466 is an overall winner.


There is one fact that clearly remains though, the 6062 seems to be making more power than the 6266 with better spool.

98RON probably

here in greece we have 98RON (93AKI)

Just gonna sell the 6062 with 50 miles on it... possibly going SX-E or XONA, which ever would interchange easier with my v-band DP and EM flanged hotside.... EFR is a bit larger in footprint to make work, though an 8374 would be ideal. I think I'd sacrifice overall WHP for spool and broader powerband.
