new turbo set-up.

I know i'm not crazy! ;)

Yes everyones dyno experiences may differ that is no suprise. I do not need to research because I have seen enough to know that Dyno dynamics are a heartbreak dyno for sure. Its just more fun when we bring a 330whp time attack car and pass the same kind of car claiming 450whp (event last year). That stirs things up, and makes people realize that dyno #'s dont win races.

As far as your numbers, the Blitz supercharger platformis not a good way to compare dynos. That set-up is very inconsistant and is the main reason I sold it years ago. A 4pk belt pushing a roots type suprcharger is a bad design. More times than not the belts slips and boost drops before rev limiter. Depending on temperature the belt tension changes and has to be constantly monitored. If it is too loose it slips and you loose power, if it is too tight it binds and you loose power. I finally found a sticky belt and I started shearing crank pully pins. At the dragstrip I had to spray VHT on the belt to ensure full boost. The set-up is fine for street use but I was always fighting to keep consistent power at the dragstrip especially since I mostly bracket raced.

No need suggesting for me to do research, that is my job. A dyno sits 20 feet from me every day. I race, go meets, been to many other dynos and performance shops. I have a pretty good idea on what dynos read what.

On another note, I was able to place 3rd in Mod FWD in this past weekends Redline Time Attack. My friend and racing buddy Ken Fox placed 2nd in his 332whp tC running our turbo kit and fuel system (stock motor).

My car did amazing, only issue was hitting speed cut early down the main strait. That killed my time, I would have been easily at 140mph before braking zone.

those are some big ass injectors!

nice setup, looks very clean!

Thanks man! Yes the injectors are huge but still I need to upgrade the fuel system to get their full potential.

that girl is hot....

just take 2 minutes to research it online. you will see the dynapack reads lower than most all dynos.... promise :)

I just had a chance to check out comparison as you requested. I got mixed results. Seems like the s2000 guys confirmed the dynapack reads higher than dyno-jet, along with Subie guys. Some people say the opposite. I would say it is inconclusive.

Now if you take a bit of time as I did for you my friend, you will see why I mentioned other dynos. Dyno dynamics is the true heartbreak dyno.

I should not have even mentioned dynos because everyone has their set ways. But like I say, the dragstrip does not lie. Try it for yourself man. When I was at 133whp I was able to run a 14.7 @ 91mph. A Yaris being a bit lighter should have no problems running 14's with nothing but a Blitz charger right? Somehow I don't see that happening. 116whp with my Blitz charger got me a 15 flat once or twice.

Im hitting up the strip this friday, stay tuned! If I can put the power down decent, 12 second passes should be within reach!!

Hey,

Thanks for looking into it. You are right, people will always have different answers for that. Anywho, I wish I could take it to the drag strip, but Oahu was an IDIOT and closed down our drag strip. Yah, I have no idea what to say about your comparison of a yaris that was stripped down with a blitz and it'd be able to run a 14 flat, no clue! I put down 140whp on a dynojet, so maybe i'd be able to do it? But I doubt i have the driving skill to achieve it.

That stuff you are saying about the blitz kit earlier with the belt problems is kinda discouraging. I haven't noticed any belt slipping yet? But I don't autocross or drag the yaris. However, I am getting the kit tuned with a greddy emanage ultimate this thursday, and am curious to see what kind of numbers they can squeeze out. Hopefully I don't run into those problems.....

just keep an eye on the boost gauge make sure it holds boost till redline. Also the Bando belt the kit came with was strong but not sticky. If you can get the correct length Gates belt that would be best. Also, that belt length is RARE to fing in a 4pk width. So I got the correct lenght in a 6pk width and cut 2 ribs off with a utility knife, I got so good at it the belt after cut to a 4pk was like new out of the box.

Gosh no dragstrip? is there a roadcoarse or auto-x? I'd pull my hair out!

Hey,

Yah I didn't use the belt that came with the kit. I ended up doing exactly what you did (cut the 6pk belt into 4pk). I will keep an eye out on the boost gauge.

Yah man, no drag strip. It is pretty dumb, especially considering there are so many wannabe street racers around here. However, there IS an autocross thing they setup at our local stadium's parking lot. Other than that, no race course or anything! Lame.

I was there yep. I hope they do those again that was fun.

Hub dyno's (Dynapacks) read higher than roller dyno's (Mustang, DynoJet, DynoDynamics,Land & Sea, etc) by design. There's less rotating mass since the wheels are removed. But every one of those dyno's have software in different locations so they will all read different, EVERY SINGLE ONE. DynoJets are the standard because as someone mentioned, they are the most popular and widespread. Reading low or high means nothing in the long run since a dyno is only meant to measure progress to a delta, not a absolute ceiling.

Also as previously mentioned, trap speed's don't lie and are the most accurate method of comparing power.

And for the record, Greddy Emanage Ultimate sucks ass. I've seen and used the software and I would want nothing to do with it. It looks like something programmed on an Atari. And with it being a piggyback, it is very limited in what it can do - hardly "Ultimate". Not a knock on anyone using it, just my personal opinion.
