NA power

[cypher02xd]

a n/a motor can only do so much. unless you dive into internals you're extracting barely anything out of the motor. a n/a motor can only breathe so much and do so much.

the name of the game is efficency. namely volumetric effiency. how do you increase efficency? its simple. you find a way to shove more into the combustion chamber that whats already there to create a bigger "burn". the easiest and most effective way is with F/I.

the only way you're going to get a good amount of power out of the motor is if you decide to spray nitrous. i'm not bashing your decision to stay n/a but don't fool yourself into thinking you'll get 250whp or something out of it.

My mkII is NA so I'll just throw my experience in on this...

Dont waste money staying NA. It's freaking BS and you're throwing good money away for minimal gains. Like $800 and I LOST 3 hp (intake/header)

Thats my advice. The Doug Thorley header and intake REALLY helped with throttle response and seat-of-the-pants torque, so I would do that if you gotta.

You actually lost power? Hmm.

Forced Induction is good, granted, but you dont need to give up on N/A's completely. Too many people are eager for 'the quick fix' of just upping the boost and getting a few bolt on bits to make things go faster, but if you REALLY want to change things around and turn a few heads, then internals are the only way to go. Before my days of Escort RS Turbo's, Cosworths etc, i was taught that to build power, internals need to be done first before anything else.

Some of the internal work is pretty easy, and can be done by yourself. With the engine out - strip the head and the block, take both to be hot tanked, skim the head by 20 thou, get a multiangle valve cut with 3 faces, port & polish and make sure your exhaust manifold doesnt foul on the head - ie, everything flows smoothly. Pistons, stock will do, but forged ones are obviously a good thing. Next, get your crank shotpeened, knifedged and balanced. Rods are up next, get them balanced too, fit good quality bearings and ARP hardware.

Of course, intake is important too, so you can either just get a FIPK and be done with it, or you could ditch the 7M-GE's electronics and go for a custom ECU and throttlebodies. Jenvey make a nice line of TB's. MBE make a nice custom ECU too thats fully programmable - the 941 should suffice.

Just my £0.02

^ Dyno proved it. :icon_bigg

*edit*
I think everything is just... I dunno. It's all a bit much for my little 6m I think. It's at the end of it's abilities w/o mucking around inside the engine. It's not really that i've given up on staying NA, it's just i can't afford to keep taking on 3-4 hp for $500 or so at a time. (so it seems, anyway)

I was at 163 last year at Chicago, I believe I was at 160-161 this year. This is even w/ electric fans, also. and heat was deffinitely not an issue.

I honestly don't get some of you guys Riffing on the na models. Na is a choice. I like my natural power and will place it's longevity against a track ready full on set to race mkIII. Something on the Race set up will give before my oem Stocker. It's plenty hot. If you think that you need a faster car, BUY one. Don't punish your na because you didn't know what was what way back when or whatever. Some of you guys need to trade into a Honda. Because supra...., n/a or turbo'd is a lifestyle. Some of you might be faking it. Hard to say. These are only opinions and there is a reason they are free.

Even though you dynoed less, I still think there was something wrong else where. I don't understand how doug thorley headers (supposedly the best ones) and an intake could have made you lose power.

Also, maybe it's a 6M thing, and not a 7M thing?

Go turbo!

Ok Clip lets add up some things.

SAF-C - 250
Headers - 250
Cat-back - 300 ish
Intake - 150
Wideband - 200

Thats 1150 right there.

You can pick up the full GTE electronics, ecu harness and ALL turbo parts--

For under that.

ANd trust me, the power will increase exponentially. Ive done months of thinking on this topic.

Turbo is THE best bang for your buck, once you go turbo the possibilities are endless Clip!

Maybe because "The Weather Man" posted exactly what you did, had a "-William" at the end, and you changed it right now.

Ok, are you done being an asshole? Did your off-topic post serve its purpose?

Stay on topic.

For under $250 i bought a stock ct in good condition,stock turbo mani /w heat shields,stock bypass valve, and stock intercooler. The price includes everthing fully deliverd to my house. Thats cheaper than the price of headers and the gains will be far more.:naughty: Between ebay and the boards parts for a full na-t can be had relatively cheaply

 

[supramacist]

I wonder what diameter of exhaust pipe he went with????? If he went to large is the only way I see a loss. But I'm not a mrchanic. I just work on my own shit.

 

[mkiiSupraMan18]

it's all the same size from the header back... 2.5" or 2 1/4", I don't actually remember it's been so long.

But in all seriousness, we (my buddy and I) think that my tach is off in my car so the readings were F'd from the start. So it's hard telling actually. I'll find out sometime next dyno season. :icon_bigg

You got damn lucky!

I think im over the 2000 mark as of now with my NA-T, but that includes a 57 trim, BIC DDP and a whole assortment of other goodies

Im not lucky, i was just patient on waiting on finding the parts, but i was lucky i had money at the time

The price will go up significantly once i do turbo rebuild and "goodies" along the way, but strickly speaking on stock parts deals can be found.

i swear to god, will; you only went turbo so you could rub it in til you forced me to go turbo.
