__________________________________________________ _____________ Engine Dyno Tests 6G72~2JZ-GTE Hello Community. These dyno tests were taken from a live engine dyno using brand new and broken in(50hours) 6G72 and 2JZ-GTE engines. I tried to make the test as consistent as possible with both engines using the same aftermarket parts. The T76 Turbos were swapped and used by both engines to measure any inconsistencies. This was a long test that has been going on for nearly 5 months. I spent over 400hours trying different scenarios, too much to write down, suffice it to say I tried being as accurate as possible. Stock rods were used on both cars. Here are the results. Stock 2JZ-GTE= 331hp@5633rpm's Stock 6G72 4b= 314hp@6028rpm's T76 2JZ-GTE= 387hp@6292rpm's@10.0psi's T76 6G72 4b= 384hp@6708rpm's@10.0psi's T76 2JZ-GTE= 571hp@6424rpm's@15.1psi's T76 6G72 4b= 593hp@6722rpm's@15.0psi's T76 2JZ-GTE= 682hp@6610rpm's@20psi's T76 6G72 4b= 714hp@6784rpm's@20psi's T76 2JZ-GTE= 766hp@6641rpm's@25psi's T76 6G72 4b= 809hp@6812rpm's@25psi's Note: More than 2 dyno tests of each pressure was taken and these were the highest HP numbers recorded. Suffice it to say that most of the time the numbers were only different by a maximum of 1-1.5hp. VP Race Gas was used in all tests. Stock Heads, Blitz 850cc injectors(full sets swapped 4 times between cars), stock valves, stock pistons. Consistent A/F throughout range, same for both cars, no detonation found on 116. I used a K&N on both engines connected directly to the turbos. I used a custom HKS Titanium 3" exhaust on the 6G72 and the HKS Titanium 4" exhaust for the 2JZ-GTE. Custom 1.75" headers were used for the 6g72 and an RPS Header was used for the 2JZ-GTE. **Note: no auxiliaries were used, air conditioning, power steering, etc... so HP figures will be lower with these in place** Joe, I used an SDS EFI to control the injectors. The 2JZ used a Greddy 4 row and the 6G72 used a Custom FMIC. The large fan was blowing directly on the intercooler for testing. Stock Radiators. The temperature was 15degrees C in the room and we inputed this information as well as humidity into the dynomometer. HP Numbers are in SAE. __________________________________________________ ______________ So oem vs oem the supra wins. But once the psi goes up...i wonder what makes more power? Try again noob. Oh btw...the 3s has 33 degrees of overlap stock. I know the 2jz can hold a shit ton of power, but no-one in the 3s community until lately has used anything BUT td04 turbo's. Just this year td05's became popular and people began to discover turbo's by this mystery company called "garrett". Here is the thread. linky T76 78LB/Min, 1128 cfm @ 2PR @ 65%. 93LB/Min, 1345 cfm @ 65%. 38psi max boost determined by compressor rpm http://ztechz.net/sitebuildercontent...ctures/t76.jpg |

you're right, i know nothing. i'll crawl back into a corner now..fuck the world.

3/S = teh lose. The End.

Re: swanny's sig
supra heads are nicht so gut, but thats common fact ;)
|
Re: swanny's sig
Yes, the supra head sucks, or as shane would say "Nothing to write home about".
But then again, 3/s cams suck. I dunno, we'll just see how much power my shitbox makes this spring. |
Re: swanny's sig
is there a reason there were no 3/Ss in JGTC?

Re: swanny's sig
Oh yeah, the Supra record is still 980hp on stock bottom end, right?

The GTO did race in N1 Endurance but according to Taishi (the guy at the Mitsu cookout with the two yellow 3Ss) they weren't really production cars. Here's a quote of his from 3Si. (I'd love to have on of the N1 cars for all the weight savings they put into them) Quote:

Re: swanny's sig
They replaced major parts of the interior and exterior with lighter parts. If I recall right Taishi said they replaced a lot of the heavier body panels and the doors. I'm sure those three race cars each had over $100,000 into them. A 3000lb 3S would be sweet.
The bolts-on are obviously pretty weak for todays standards. |

Re: swanny's sig
The horsepower numbers with the 6G72 4b and the 2JZ-GTE are interesting, but it does make sense. I don't think anybody here is saying that a 3/S can't make power, but how usable is the power going to be when you can keep things from breaking?
|
Re: swanny's sig
I don't know, how useable are dsm's? They constantly break, why bother trying to make power? We aren't shredding gears in transmissions (like shane), we just bust transfer cases and are currently bitching on how completely stock motors don't hold 35psi with twin evo 16g's.
Real problems ;). Billet transfer case housing, stronger non rusted output shaft, front diff upgrade for safety. Put in a clutch, back to bulletproof drivetrain (within reason). |
Re: swanny's sig
Well considering the fact that there are tons of DSMs in the 10s and some even in the 9s on stock drivetrain I would consider them fairly decent. Everything has a breaking point and that has to do with a lot of factors. The only real problem the 3/S has is that its a touring car. It has tall gears and is really heavy. For a drag car application that combination does not mix in my opinion.

Re: swanny's sig
Really heavy as in 300lbs more than a Supra? Considering its AWD I don't see that being too bad at all.
How is the 3/S being a touring car a problem? It is what Mitsu designed it to be and is damn good at it. It is very stable at high speeds and has no problem negotiating high-speed corners nor getting a good hole-shot. I really don't understand why DSMers hate 3/S's so much; is the "younger sibbling" jealously really that bad? When it comes down to it, the 3/S is really nothing more than a larger/grown-up DSM. I'm personally done talking about Supras; they are great in their own regard and pretty much everyone here admits that, but, how many of the 3/S haters have actually had a chance to drive one at great length to get a feel for its true qualities and strengths? |
