hope octaneguy doesn't mind me answering the question eh eh
16% pulley cai detroit bypass valve, exhaust...

 

Cool - thanks. I'm hoping to see results at some point for a non-pullied car so I can see how the gains will compare to the cost.

 

The results look great! Is Jan working on tuning R56's yet?

 

How about a Colorado Visit Jan?!

 

What's an R56 .

Longboard

 

Thanks! I talked to Jan about larger injectors but he didn't recommend them for my situation, but one day when I get a head--after this feeling wears off and I need even more power, lol, which hopefully won't be for awhile.

Definitely. Definitely the best bang for the buck!


Here's what my graph looks like.

Super hot.

 

2 more in the 240+whp club
charts to follow

 

Ok, first Let me say that I'm not trying to cause any hard feelings or any dramma. I'm Just trying to understand how a dynapack works. I see that Jan dyno'd both cars in this thread at 4.61 gaer ratio but, The guy's at Alta uses 4.1 ratio and I used a dynapack two weeks ago and they used 4.1 ratio.
Why would that ratio change when it's the same type of transmision and car being dyno'd . Doesn't the higher 4.61 ratio yeld a higher dyno number?
any answers that help me understand will be greatly appreciated

 

Very nice. The best part is the extra TQ.

I still need to bring you my car. I'm hammered until the middle of January so I will call you around then.

Man you did a nice Job on my Buddy's kid's Miata. He is home from collage for the holidays and was shocked at how nice the paint looked .

Thanks!

Longboard

 

Just so everyone is clear, I have most of Jans stuff on my car and he tuned my car

 

No problem. This month is slower for work which is nice cause it's so freakin cold!!! LOL. Thanks for the compliments on the Miata. Yeah that was a fun one.
As Jan would say, it's the Delta that matters. I think the year had something to do with it--both of our MINI's are 2005's. But that's about as much as I know.

 

doesn't 05's and 06's have the same gear ratio's

 

Yeah, I couldn't tell what year yours was based on the sig--so that's not the issue then.

Here is another RMW HEAD/HEADER combo
the "red" run was a test of a/fs and timing with the 440cc injectors
purple was the first full run to 8k
yellow was the final run of the day

245.8whp
187.8 ft lbs of torque
car has around 66,000 miles on it

 

Jan -

How does one setup a tune with you? Do you only tune in California?

 

They are setting up dyno days all around the country. I am leaving for Detroit today to dyno cars Sun/Mon, then off to Dallas on Thurs for the weekend.

Philly is the next date on January 16th-19th

If you are interested in setting something up in Chicago, contact the local clubs and try to put something together. I am up for going , but you will need about 10cars minimum.

 

one day i will get mt car tuned like this, one day

 

Can someone explain in simple terms the relationship of Torque versus whp?

I understand that I gained about 20HP and 10 pounds of torque after my tune and that the torque number is more important.

Looking at this tune with the head, I see that he's got 43 hp more than mine but about 5 pounds of torque difference. Jan told me that normally you can feel a 5 to 6 pound torque increase pretty easily, so that my 10 pound was very good.

My question is--if this particular dyno only showed 2 pounds of torque increase and 30hp gain, would I have felt a difference??
*********

Btw, 5th gear on the highway at 4,500 RPM is AMAZING after the tune. There is so much power on tap now--love getting pushed back into my seat, and maybe it's just the way I'm driving now to take advantage of the power, but the exhaust note seems to be even meaner...I love it, lol.

Thanks

Richard

 

Oh wait, I think I know part of the answer. Jan reminded me that the Delta was the most important thing not hp. From these charts, I see after the head he's got about 13pounds more torque which is huge.

 

Torque gets your started, horsepower keeps you there.

Use to sell Peterbilt trucks.

Thats how I use to explain it to customers.

 

Oh that makes perfect sense. Thanks!

 

Truly impressive #'s for the RMW Head/Header combo.

After selling my E30M3 this has got me really thinking of a Mini track monster. I can only imagine how crazy the Rotrex kit will be on top of a RMW Head/Header combo!

Gotta love these little 1.6 litre powerhouses

 

Yep - when you test a car on a dyno, it's actually the torque that's being measured directly, and then the horsepower is derived from the torque number. In fact, the formula is HP = (torque X RPM) / 5252. That's why when you look at a dyno chart, the horsepower and torque numbers are always identical at 5252 RPM.

That's also why small-displacement sportbikes and things like Hondas/Acuras can post such high horsepower numbers while having very little torque - their engines can rev to the moon. Likewise, big diesel trucks can have 600+ ft-lbs or torque, but "only" 325 horsepower - they simply can't be revved very high, so that limits the horsepower.

As far as how a car "feels" when you're driving it, torque is what determines acceleration, while horsepower determines top speed. For a street-driven car, most people will be happier with an extra 5-10 ft-lbs of torque across a wide RPM range than they would be with an extra 20 horsepower at 6000+ RPM. You can pick up an extra 15-20 peak horsepower just by raising the RPM limiter, but how much time do you spend at 7000 RPM?

 

Thanks for the additional info Scott. Much appreciated.
