The problem with manifolds is you can build one that works well in one part of the rev band but it sucks in other parts. So you end up with a compromise that works across the whole band. I used to own (well, still do) a 1995 Interga GS-R which had variable length intake runners that switched at 6200RPM (lots of people thought this was the VTEC switch point but it wasn't). So from 0 to 6200 it ran the long (dramatically longer) runners and 6200 - 8200 it ran short runners. It used vacuum to open 4 butterflies that sat in the middle of the manifold. Something like that would probably work well on our car and would probably solve the "dip". Problem is it adds weight and takes up more room. Something like this would probably cost as much as a turbo if it was an aftermarket thing.

I would be happy if someone came out with a manifold that only made more power from 4500-7200 and sucked everywhere else.

YES! Exactly! Other manufacturers use it. It’s not black magic. It’s like having different manifolds, each one for a different part of the rev range.

This is essentially what Honda did on the Integra Type-R. They ditched the dual plenum intake and went with fixed short runners. My GSR pulled harder at low revs in but once we got into the upper band the Type-R would walk me hard. The Type-R was more purpose built so they didn't care about the lower band because you shouldn't be there anyways. They also wanted to shave weight.


My boy racer days of never running under 4K were over 15 years ago. Today I'd prefer the dual plenum setup and more usable power at lower bands without compromising the upper band. But yeah, I totally get your desire for a manifold built solely for the upper band.

I always have an issue with stock seats and a helmet but I'm 6'2" and need room for my legs and torso. He appears like his legs are extended out too rather than simply being in a comfortable position (supposed to be able to depress the clutch with you right foot).

Either that's not his car or he never had an instructor look at his driving position.

We were talking basically on plain straight speed performance like at 9:36 which is irrelevant on driving position.

Doesn't look too bad. I usually find it more comfortable to set my seat so that I am comfortable with my pedals. For all you know he is long legged.

More displacement and torque sound great. (as long as it still revs) if the renderings are accurate it’ll be a much less beautiful car. It looks pudgy. The fender and rear quarter shape of the current car are really killer. It’d be a shame if they messed them up.

Back in the day of the "lay down flat" driving position it was customary to have your arms nearly straight out. You could not bend your elbows much as there was precious little room for them. With little weight and low down force on the front it was easy to turn the steering wheel as no real effort was required. With heavy, front engine cars you needed to have more bend in your elbows to have greater leverage on the steering wheel. Then along came power steering and the more relaxed, laid back driving position came back in vogue. Yes there are "rules of thumb" that some instructors insist on hammering home but... in the end it's up to personal preference. Lots of articles on line that push one over the other. This one from down under gives a good balanced over view of steering wheel position.

When I was working/racing with the Bridgestone school I preferred to sit as low as possible and use the old school "arms out" style.

Agree. The purpose of the video was to show that the 2stage intake manifold doesn't make much of a difference. At least not on this motor. There are plenty parts in the video to show this, independent of sitting position or other "errors".

I posted this on the fan art thread, but for those that missed it.

Edit: I tried to remove some of the random watermark letters that he throughout the car. Don't judge, MS Paint was all I had to work with.




For those that don't like the Supra nose.

You do not have to look that far back. The Mazda MX-5 ND was lighter than the first gen Mazda Miata when comparing the 2016 1.5 liter equipped car against the original 1.6 liter equipped Miata. Even the 2.0 Liter equipped MX-5 sold in NA for model year 2016 was lighter than both the NB and NC versions.

I agree that it is great news that Gen 2 will be lighter than the previous gen if that actually comes to pass.

Thank you Subaru and Toyota!
