So yesterday I finished installing my $100 HDHCDD bar and after I was done I took my car out for a test drive with out the pass seat, back carpet, plastics and all the little stuff you have to take out to do the install. The car was way faster somehow and I doubt is the 50lbs if that that I lost from seat and stuff cause the rollbar alone was probably 50lbs. And I know I'm not dreaming cause my car was burning up second without even trying. So WTF is going on?

 

Chassis isn't flexing in the rear as much and you're just putting the power down better would be my guess.

 

That's what I was thinking too, but it's an amazing difference. Best bang for the buck especially at $100

 

weather change recently? cold air == better than

 

placebo?

 

Honestly, cold air is so over rated. Like it would have to be such a massive difference in air temperature to have any real noticeable effect. It's unreal how stiff these bars can make our cars. I just installed one in a friends 92 turbo miata and pretty much straightened the car with it.

 

Actually cold air is much more likely than wight reduction or chassis flexing. I my self saw a turbo civic pick up 10hp with cold air intake on a dyno.

 

Same temperature. I was driving it the day before and it was in the 70s as well

 

wet road?

 

someone aired your tires to 50psi in the middle of the night

 

Are you really that clueless? My IAT's can vary 18 degrees from day to night.

 

Agreed.

Hot afternoon in traffic 104F peak, cruising at 110kph 80F.

Air temps make a huge difference, and no your roll bar hasn't made your car faster, I doubt "chasis flex" (with all the torque miatas make) is likely either. Road was prolly dirty or your tires are alittle more worn out then they were yesterday

 

Idk I'm just confused but for sure my car felt better. Either way I'm not complaining

 

But did it have a performance intake before that? Maybe it was just a better flowing filter. With 2 years of dyno experience, and lots of befores/afters, on most applications there was little benefit on a cold air design over a really good short ram design.

 

Except on the dyno you have 0mph airflow (a barn fan doesn't really count), so they should be nearly identical. When you're moving down the road a cold air intake is an advantage as heat soak is completely non-existent and you always have ambient intake temps, the short ram is now pulling hot air from behind the radiator, exhaust mani, etc.

As far as weight reduction I can clearly feel the difference between having a passenger or not, but something smaller than that I really can't notice at all.

 

Before it had a filter just on the turbo after we put it with an elbow right directed at a huge fan.

 

Btw, I did feel a diffrence with my Miata when I removed all the ac guts and compressor.

 

I think the *** dyno needs to be recalibrated

 

Maybe, I would take the car out for a ride again but the car is in pieces again for the 80th million time

 

I think the real question here is how the hell did you get it for $100?
