Thanks again

Re: Making Hp in a NA
 

that's an oxymoron :D.

Damn. For all these years, I could have swore that my rx-7 was rear wheel drive. :cool:

Dope, that's flywheel horse power. Stupid me.

im sure you can make over 200hp on a s5 na engine with a custom intake manifold with the stock ports and the standered exhaust mods. Just look at the stock NA manifold, do you think thats maybe a little restriction? the air has to make a complete 'S' before it even gets to the engine, and im sure all the coners the air has to take is not a smooth path either.

HA, oh the irony... Aaron Cake's WAS an N/A....

I don't understand the controversy over Aaron Cake's TIINA.

Seems like he has taken more heat over it than gotten any applaud for it.. (at least via the threads I've seen).

Essentially the difference between his engine and a regular TII engine is the static compression. Everyone one seems to say "Why didn't you just get a TII?" well.. it's his project.. theres nothing wrong with higher compression on a turbo, you just have to know what your doing, and prevent detonation, etc.

It's not like he just slapped on a spool and went away.. He has an SAFC, bigger fuel pump, injectors, the works.

So, he's running the same amount of boost as stock TIIs, but has more compression, which as far as I've learned, would mean more power, right?

Unless I'm missing something drastic between a TII and NA (biggest difference is compresion.. don't "6 port" me! ;)), or have been wrongfully misinformed about the project..

Just had to get that out.. been brewing for a while.

I would say if you want to do anything to your N/A engine, try a turbo project such as Aaron Cake's.

Doesn't bother me. The car is faster then probably 90% of the NAs and TIIs here...:)

The only "hard part" that is the same between the 13B and the 13BT is the eccentric shaft. Everything else is different.

I've run 12PSI...That was fun, but didn't have enough fuel.

Different engine, suspension, interior. However, I quite prefer the simple interior of the old S4 NAs, and they are the lightest 2nd gen.

I don't recommend that.

Hmm. I didn't know this.. Rotors (compression), Housings (Exhaust Baffles), LIM and UIM, Exhaust, meh.. That's the meat of it, so I guess I wasn't thinking on the proper plane.. Essentially though, biggest difference is the static compression right? ;)

Erm, I mean however if you are serious about doing something to an N/A engine that involves no longer having it naturally aspirated (as superchargers and nawz came up).. Myself I would do something turbocharged after considering aspects of the style of superchargers you can use, or the nos..

don't feel bad, most intelligent people use BHP.

:rofl:

I was going to say something, but didn't.

You can make HP in NA form with increased compression ratio, increased volumetric and / or thermal efficiency, fuel mixture fine tuning, porting intake manifolds and the air flow meter, porting the engine's intake runners and intake ports, porting the exhaust port and removing the diffusers, buying a header, fabbing a ram air intake, buying and installing underdrive pulleys, correctly installing an electic fan with a temp switch, playing with the ignition timing to help whatever rpm range you want to pull better (advanced timing helps the top end while stock timing is designed for good midrange), and last but not least, tuning up the entire fuel injection and ignition system.

In other words, it's all in the details.
