Dropping the 0-60 on the first gen?

[youngq45r]

Any body know some good ways to get the 0-60 down? besides the nico-ecu. and 4:10 gears? I've wondering about a gearvenders overdrive/ underdrive unit. But thats like 2-3 grand. i'm more so looking for cheaper acceleration (arn't we all) but... with a Q nothing's cheap. Thought this would be a good topic for everybody to learn/benifit from. Thanks for all the help.

[elwesso]

NICO ECU is the start. A good choice however would be a high stall torque converter. Really, the car isnt geared for 0-60, it was designed to haul arse after 60... So maybe thats a sign...

Of course, nitrous is the easiest way, however I dont like it. It feels like cheating (which it is)

[youngq45r]

tru. witch i want really bad, but every time your running them im broke. hhahha damn. But seriously, and overdrive/ underdrive unit would help alot wouldnt it? you could split you gears, for the track, or double them for the freeway. great on quarter mile and on the gas millage. the cars got the power, you could drop those rpm's down to 1500@65 or so right? or am i missing something?

Who realy cares on a full size luxury car?

Who stops accelerating at 60 mph?

Guess I don't understand this fascination with an old Tom McCahill specification from his Mechanix Illustrated Magazine car tests.

Remember he tested trunks by having his labrador retriever climb in? I am sure it is just as relevant.

[youngq45r]

Full sise luxury car, yes. But more importantly, to me, it is the ultimate sleeper. She is an amazing machine, and im just trying to improve on some of the low spots. Not to mention, i race, alot. That i what gets me going. I do drifting. Top speed running. Autocross. U name it, i,ve tried it or am going to try it. Some day i am going to build up a Q for the bonnivlle salt flats. Get a Q over 200mph. And another for the TV show PINKS. Run the Quarter mile in 9-10 sec.I'm sure there are others like me who like there Q's for the speed and power reasons. Others like the low and slow. And some just like them.

And knowone stops accelerating an 60. But when you only have 1,320 ft to go as fast as possible and to beat the other car, the faster you get to 60, the faster you hit the cars tru power of 60-120. (thats where i feel i the most)

[jimbyjimb]

Nitrous. The cheapest power adder. You could easily run 100-150 hp boost on a Q.

Oh brother.....focus on school

[youngq45r]

Tru, That relates back to the other thread i started about NOS. I want to spay it badly. but NO is dangerous. im not sure i want to do that... yet. got another motor in my garage that will be my spray motor. Once i put out the money and do a full rebuild. But i'm looking for other stuff. _NICO ECU- No Downside. first thing to get _Stall converter- only down side to that would be gas millage _NOS- BOOM _Carbon Fiber Drive Shaft- Not worth the money... yet _4.10 rear end. Again, not worth the money... yet _Electric fan's- that would help. not sure how much tho _ Intake- I dont mean a free flowing filter that sucks in hot air, i mean, just larger intake ducting from the airbox out, with a K&N filter.

What else? just thro out ideas. it cant hurt

[youngq45r]

Oh, probably should chang my profile, all ready out and working full/ over time.

Turbo?

You're considering large increases in 0-60 times (meaning lots of gas) and you're worried about gas mileage?

Something's gotta give.

I know I never stop at 60! Seems everytime Im on the highway, im always doing at least 90 and that I always have followers (guys) wanting to run with me, but never seem to keep pace with me. I think thats her cruising spot, lol. Although I did have a newer model Infiniti with me Sunday. Now that was a sweet car. OK, not sure what this has to do with your original post, lol.

[Kiven422]

I like the Q for cruising and because its a 4-door... that has mad power. Two cars were racing, coming behind me with speed ... I stepped on it and started walkin away from them... they couldnt believe it

I think the car could do 65MPH under 1500RPM if there was another gear.

I'd like to add all the power I can without forced induction.

-The NICO ECU. Don't have it but 60mph in first gear should be good.-A fresh oil change. One little big difference.-Sport springs may help--reducing squat, waiting to put my eibachs on.-Cheap gas gives slightly more power... before racing I try to fill up at an AM/PM whenever I can. Best to have only a 1/2 tank.-Intakes help. I use the ram air style duct from the 90-93 Qs on my 94.-Tires that spin easier let the engine rev higher making less time to get to the power band. An increased launch on this car.-Brake torque launches isn't a big deal. I usually just smash the gas.-Extra weight in the backseat or trunk makes a noticeable difference.-Kick out all passengers.-Launch in first gear, always.

Those are just the little tweaks that help because every bit of horsepower gained counts. Theres more just can't think of them.

-Cheap gas gives slightly more power... before racing I try to fill up at an AM/PM whenever I can.

For some reason this doesn't make sense to me, thats why racing fuels are high 100+ octane gases. I can get 116 octane at a shell here for $6.16 a couple of months ago. I would never put cheap gas in a Q45, or in any car a matter of fact.

If I had the money and tools I would go with the turbo option just because of its advantages vs Nitrous.

[youngq45r]

I think the car could do 65MPH under 1500RPM if there was another gear.

I think you right. Thats why i would love to put a spliter on it. cut you gears in half, then double them. Tho i dont know of one that would fit the Q. have one on a friends 2002 Z28. he cant split first because he just boils the hell out of the tires. but the rest... 1st gear. 1st 1/2. 2nd. 2nd 1/2... crazy accel. I'm liking the ideas. Any body every used the Octain booster made by NOS? I will guarentee you that it helps. Pulles EVEN HARDER at peak rpms!! 10 bucks a bottle. Not a bad deal. good for 1 tank. and its 1 FUNNNNN tank.

[youngq45r]

ANybody ever try that tornado thing? it spins the air in the intake, makes a vortex. wonder if it works...

[Kiven422]

I don't think i'd ever put racing fuel in my car. Need something streetable.

I believe those Tornado intakes make the engine slower. I don't know though, thats just my opinion.

[Q45tech]

Luckily any obstruction in the air passage depends on the flow rate until high rpms and high flow rates it is almost transparent.

Why air filters, fancy duct work, and cone filters do little to affect idle and cruise 1/50 of peak air flow is occuring.

When air flow is down in the 5-8 grams per second range vs 250 grams per second at 6,000 rpm and WOT.

You could block off half the area [like a restrictor plate] or like the throttle does at cruise [95% at 60 mph] and not change anything.

It is difficult to even measure any restriction in front of TB plate because ratiowise everything else is so very very tiny at cruise compared to 95% restriction of throttle. Think how small the IAC valve [tiny piston bore] is compared to 77mm throttle plate.

Everything is designed so that at 4,000 rpm [torque peak rpm] only 1% restriction occurs prior to TB.

Translation for you who haven't read the many previous threads (and we can tell who you are by your posts!), K&N, RamAir, PopChargers, custom CAI, etc. won't affect power positively more than +3 HP in winter (and usually -20 HP in summer), but will noticeably shorten engine life by admitting larger contaminants to the engine.

Too many people don't realize that every engine is supercharged [pressurized] by the natural earth's atmospheric pressure.

Hard to make improvements when this 14.7 psi is refilling the engine! When the heat expansion empties the cylinder, the atmosphere rushes in to fill the void.Reducing any restrictions by 0.1 psi even 0.2 psi is hardly significant.

Same with exhausts, hard to restrict [stand in the way of] a 1200 degree F gas expanding into an open exhaust port.

[youngq45r]

Wow guru, Where did you learn all this? That info is insane!!

Yea no real gains. Most of the extra HP is in your head. But it does feel like the engine revs a little more freely. I might take out the STILLEN intake tonight, its so loud and annoying at idle. I'm going to put the stock back on but with the 92 ram-air style duct.

I noticed on honda accords (4cyl) intakes increase gas mileage. Doesn't work like that on the Q45 unfortunately.

Best for performance and longevity to revert to stock CAI and filter setup.

Man, now that i have faster internet, i just might try those coarses. thanks
