Agreed.

 

Damn this is badass so far. Very jealous sitting here right now.

 

Hey synapse did you guys have your turbo balt out tonight 11/07/08 at sears at the Rotterdam Square Mall? I drove by with my SS/SC and I saw a black SS/TC with a front mount intercooler and a bunch of guys standing around with some other cars. Probably would have stopped but I had to get my wife home.

 

Thank you.

 

definately not true. torque drop off can definately be dependent upon the turbo being used. torque drop off varies based on motor efficiency, turbo sizing and efficiency, and other factors. not just a given 5250. most engines run out of breath between 5 and 6k because they aren't efficient enough to keep filling up the cylinders during the intake stroke. the piston moves down so fast the air cant fill the cylinders. this may be due to insufficient cams, portwork, turbo cant supply any more air, exhaust is too restrictive etc. look at honda motors, they almost always have peak torque above 5252.

on a turbocharged platform the engine is relying on the turbo to compress air to fill the cylinders. if the turbo has reached its limitations it can no longer flow any additional air. so as the engine increases in RPM, the engine is still consuming the same amount of air, just faster. assuming the turbo reaches its max at a given rpm, spin the engine 2x faster, and you will have roughly half the torque(assuming the engine is efficient enough to even consume that much air), and about the same horsepower. without more air you can't make more power, unless you increase efficiency.

as you can see in the example below the turbo reaches its maximum flow of 530ftlbs at around 6500rpms. 530ftlbs x 6500rpms and divided by 8800rpm, and the result is 391ftlbs which you can confirm on the dyno graph the motor is making 391 ftlbs at 8800rpm.

what does this all mean? the turbo has reached its maxiumum flow rate of X, and the engine is consuming X 35 percent faster at 8800rpm than at 6500rpm:

lol guys 5250 has NOTHING to do with torque. the only time 5250rpm's comes into play is when you are talking horsepower. 5250 isn't some magical number.

 

its 5252.

:P

please continue.

 

Yeah, I don't like that power cure, not good for the street, track yes. This little turbo should be making boost almost instantly!!! What's wrong here? As for power, this was a rather light gain in whp. As for wtq, there are some people here with all the bolt-ons and the intercooler running nearly 345 wtq and 300whp in a curve that's much more near the stock curve. Running above 7500rpm like this, you're going to need a cam if engine longevity is a factor at all too.

Bring the power curves up to near stock between 2000-3800rpms and then you'll have a good package. I'd like to see about 375-390 whp and 385+ wtq. For such small gains in tq and modest in whp, This definately needs fine tuning. Keep up the good work.

Lots of lag down low and more of it on top in tq!!! my, my i hope this thing gets a really good and like others have said, CORRECT tune.

 

Yes the turbo isn't the largest turbo by any means, but it is for a fact larger than the stock turbo, and as such it is going to spool up later, thats just physics. we are also packaging the kit with a tubular manifold not a cast manifold, meant for more upper rpm power. we are more than happy with the way the turbo responded down low. the turbo is spooling up way faster than on any other 2.0l application we have ever seen. the videos will shed a little more light on the situation.

We are very excited about continuing the development, and appreciate everyones input on the kit.

DAMN AWSOME WORK YOU GUYS
YEAH TRY TO MAKE IT A KIT,I HAVE SOMEONE THAT CAN TUNE IT ON A MUSTANG DYNO
I LOVE THE PIPING ON THE SS/TC's ENGINE BAY...LOOKS BETTER THAN PLASTIC
AND I LOVE THE BOV!!!

 

What are you talking about? The stock setup makes 260kbs tq at 2800rpm and it slowly ftapes off to 200 near redline, and makes 240hp at around 5600.

This setup is making 260lbs by 3400 and climbs all the way to 380 @ 4200!!!!(and it doesnt ever drop below 300 after that) Horsepower passes stock near 3400rpm and 160hp and just goes on forever after that, peaking at what looks like 360hp!

Thats a gain of 120lb tq and 120hp, How is that small gains? thats like putting an L61 under the hood along side the LNF



I think this is truly awesome work, yeah there appears to be a sacrifice of some power at lower speeds, bu the mid range punch of this setup is amazing, and I would be smiling with just half of what this is putting out

 

We sure did, we were shooting some footage for you guys!

 

Vids of my future set up.

 

We also rev'd it out on the dyno to 6500 yestarday and made 372whp 385tq, all without the map clamped!

 

Stop man.



Because...I will work so much overtime just to get this.

Just out of blatant curiousity...how is the gas mileage out of boost?

 

Gas mileage out of boost is just like stock, but we haven't seen to much "out of boost" driving since we put this setup on, lol.

 

Stock.

This is almost too good to be true.

 

do you guys have pics of the manifold you made?

 

Yeah they posted it awhile ago...lettme see if I can fish it up

 

 

Synapse fail

 

Fixed, lol.

 

very nice man, I'm watching this one intently.... gotta see what my competition will be on the street lol.


also as for peak tq numbers, mine falls in about 5252rpm also. 378 or 400wtq depending on what boost I'm running.

 

Wow, 372whp! What changes or fine tuning did you do to achiieve this? Also, when driving tell us about how the transmission feels, you think its putting up with the power well?

 

No changes, just some more fine tuning. We need to get a larger wastegate actuator and tq should hold out a little better as boost was dropping a little bit up top. The tranny so far loves it!
