I popped the hood after each run and during manual shifting I held it out there until about 7,3-500 rpms..."I used the force this time" as per Heavy. I did some good burnouts as well as I had did only one really good burnout on Wednesday night. Temp was a cool 82-84 degrees.

Best comment of the nigt..."wow that car is a front wheel drive"....they saw the plenum and from its position of the intake I guess one would think that it was a FWD car. I raced the Ford Escort that hanged with me on Wednesday nigt outside of the track from 90mph to 140mph....he has some Mazda 1.8 turbo and he said that he was surprised that I could hang with him as he thought he was going to leave me behind...we lined up against each other tonight and he ran a 14.476 @ 99mph. Also no offense to the Maxima guys...but there were 3 Maximas...one new 3.5 SE and two 2002 models and none of them got less than a 15.5 ET...and I thought that these things were much faster. Everybody at the track was amazed at how quick the Q45 was and a lot of people had never even heard of the car before.

BTW...if you notice the numbers....my car got extremely tired at the end of the night.

From the above stats without my 4.08...I can probably say that the 4.08 even with the extra shift adds about 0.10 the most on the 1/4 mile ET's. When I had the 4.08 I did only one true white smoke tire burn out and that was the last run of the night where I ran 14.709 @ 93.37mph...for the above numbers tonight...I white smoked my tires every time to get most traction possible.....so given the hotter tires (at that my 4.08 whinned badly) I am thinking that at most the 4.08 adds 0.10 secs to the ET, but it really does lower your trap speeds. So having said that...I am getting at leat a 4.08 or maybe the 4.36 gears put into the car as the street race acceleration factor will be a lot of fun compared to the stock 3.54 gear. I do notice a small difference in acceleration with/without the 4.08 on the street, but it is not as much of a difference as I had thought there would be.

I also need to get the JWT TCU so I don't have to do this "use the force" manual shift guess work anymore. I am also still considering the carbon fiber driveshaft, but will wait and see how things progress as I think that it will only give me maybe another 0.1secs off my ET's.

While I can see that I will never get the car to break my goad of 14.0 secs in the 1/4 mile....none-the-less...I have one of the fastest Q45's on the road that should be good enough to hold its own against just about anybody except for a damn Porsche, M3, etc.

Here are some other time slips for comparison purposes.

Here are my 1/4 Runs tonight...I did them with our NICO member FastLane which was a blast to run against another Q45 as FastLane is a great guy.

[rsiwicki]

Ohh I almost forgot for all you G-Tech guys....my car weighed in on the scales at 3,960lbs with about 1/8 of a tank of gas remaining. I did not remove any items such as carpets, spare tire, etc.

[Q45tech]

Unclear - Did you do the quarter in only 2 gears as I suggested:14.7/97.?

9.7/77 in the 1/8th shows a zero> 60 of 6.7 secs.

The problem is the span between 2nd and 3rd gear........1.544 vs 1.00..........if the torque doesn't drop by more than 1/1.544= 0.35 or 35% from 5700-7300 rpm you are better off staying in 2nd gear and not losing the shift time. From all the dyno graphs I've seem the 337 lb/ft drops about 35% at redline.

Obviously taking 5.0 seconds from 77 to 97 mph [9.7 to 14.7] is where we need to work.

The Mustang Dyno loaded to simulate the ET via weight should allow you to play with the CAS timing +- 2 degrees.....13>17 BTDC to see what works best........BEWARE the heat soak as you have seen.

Still interested in how the engine behaves with 50/50 +100 octane [nasty knock sensors].

I had a time finding the RIGHT initial advance that would be optimum in Summer it is 2 degrees lower [15] than the best cold weather [17] adjustment.

[1992Q45A]

Those traps are more like it!

Getting ever so close to 100.

Waiting eagerly for the mag article, to see what they got with a 92 with JWT/4.08/exhaust.

Did you have a bad 4.08 or something, I mean it lowered your traps by over 3 mph...

Is that normal?

[Fastlane]

Is it best to leave it in second gear and run automatic, or shift manually at redline. Will it damage the the car to run it to the rev limiter

[AZhitman]

14.7 is brutally fast for a Q.

Keep in mind that this car has 140K on the clock...

I think with some 100+ octane fuel, 2 degrees of timing advance and a little bit of weight reduction, we might see some low 14's.

[rsiwicki]

Hey.....nobody mentioned my best time!!! 14.601 @ 96.48mph!!! I almost got into 14.5xx!!! When I got so close to this on my second run I told myself I would go home when I broke 14.600, but I did not. My first 3 runs were in the very low 14.6xx....I am a very solid 14.7sec @96mph car.

I did hold the gears out there so that I had only one shift. Because I have the 95 TCU against my 92 transmission the car is shifting somewhere in the 7,300 range also, but does shift sooner than if I hold it out there just a little bit longer.

What can I do to improve my 77-97mph @ 5 secs times? I have no idea how I could set the car up differently to get it running faster in this range.

[Fastlane]

[rsiwicki]

Fastlane...I would think for your setup the best option is to let the car automatically shift. Your ECU cuts the gas for anything above 6,900rpms and your TCU is matched to shift right at this point so I don't think that human intervention can improve on this.

I am doing the manual shifting thing becuase right now I don't have the JWT TCU that would shift the car at the optimum point of 7,300rpms. My JWT ECU keeps the gas flowing until 7,300rpms (maybe more becuase I hit 7,500+rpms before I shifted last night). If I run my 95 TCU this moves the shift point up to about 7,400rpms and if I run the 93 TCU my shift point should be around 6,900rpms. I need to get a matching setup ECU/TCU to eliminate the guess work so I can just hammer the throttle and hold on for the next 14.6secs without needing to worry about when I need to shift in the redline zone.

[Q45tech]

"I did hold the gears out there so that I had only one shift. "

See I told you!

You can't trust the tach at 7,000 rpm [because of velocity of sweep] best to let the ecu do its thing. When you read with Consult you'll never see 7,300 rpms........7,250 maybe ocassiuonally real rpm.

Now that we have established that you are staying in second gear [like you should for quarter].........14.6/96 is crossing the timing light at 7100-7200 rpms.

Get a Consult and give me the 6,000-7,200 rpm: MAF voltage, ignition advance and fuel injector time in 50 rpm increments.

Gotta know how much air flow you have [4.30 volts peak or 4.4 ] .

Everything now will be extreme fine tuning as there really isn't much to play with from the plenum outward.........[only 17-19" WC restriction] would be 12 HP loss and only 5-6" is in front of MAF.

We must know if the mixture is still too rich even with JWT ecu [probably because they don't want to get sued].

You might try Redline High Temp Syn ATF it might get you 0.2 seconds [can't be used in cold weather]. I used it for 2 years in my Q transmission. At $8 x 11-14 quarts cheap if it gets you 0.1-0.2 secondshttp://www.redlineoil.biz/redtech4a.htm

Was just about to suggest that.

I'd suggest keeping it on pump gas, that way you get a real world time, not a "I gutted my car and put 104 octane fuel in it for an hour" time.



Inspiration

Get some lighter wheels too... OEM wheels are heavy. Rotational resistance is one of the final things the car has to overcome. Saves weight, and can make you quicker.

Stop doing burnouts on street tires... this just makes the rubber harder. Every time you burnout the tires will get harder. Plus the compounds work best at normal driving temps.

[Nismo_Freak]

SPL has on sale two wideband units. You can use these to help tune the car as well... save money on dyno time. You can just go driving and tune the vehicle.

They are $319 each.

If interested send me an email: [email protected]

[Q45tech]

Since he has a JWT ecu hard to tune without the software emulator and burner.

Danisiti 1

[rsiwicki]

thanks for not taking offense on the Maxima.....I know 1 of the maxima's was some automatic/steptronic thingy, but the other two were manuals and they had AF gauges and some other stuff....I think it must have been more driver error than anything else with the 15.5secs because I know from the streets that the maxima's are pretty damn fast street racer cars

Dennis....I am somewhat a fast/slow learner testing the boundaries of my Q and its myth's.....not to bad for once was only a magazine car lover guy until I found NICO this past February and decided to go on a mad rampage and modify my Q to its maxium velocity...unfortunately the truth sucks as I now realize to break the 14sec 1/4 barrier will not happen. Even though I don't have the brakes/tires upgraded yet...I need to take it autocrossing again with its new found power.

Just call me for now a "time slip junkie"....who else do you know to drive 90 miles North at 9pm on Friday after HappyHour to put in NINE 1/4 runs all in one night

[1992Q45A]

Maybe we can get the 100 mph broken...

ACPT CF driveshaft remains...

We'll see how a 90-93 with everything compares to the 94+

[rsiwicki]

The 100mph would have to be broken probably doing the 2-3 shift as 97mph is the top 2nd gear speed. Breaking 100mph with doing the 2-3 shift would be extremely difficult I would think. The only 2 mods that I have not done is the driveshaft and JWT pop charger...both of which I don't think will get me the extra 3mph before the end of the 1/4 mile. Need a lot more HP for that additional 3mph...especially becuase of the needed 2-3 shift, but then again I could just redline the shiet out of it and pray that I don't blow the engine to get 100mph. I know the 90-93 are faster...but not that much more than my car now that I have a 92 transmission.

[1992Q45A]

RSI,

Your times rock regardless...

Your traps are paticularly stellar.

The fight isn't over yet

[1992Q45A]

True..

Fred (PalmerWMD) has put down 99 trap in his 91Q.... with JWT, no headers or exhaust..

We'll see what the automobile mag article got with a 92 with JWT, 4.08, and exhaust..

I still think 100+ is possible.

[PoorManQ45]

Does anyone make a light weight flywheel for the Q45, that would lower E.T.s a little

[1992Q45A]

ACPT makes a nice CF driveshaft. Good mod, but expensive at $1,500.

[PalmerWMD]

Ryan: I did have exhaust in my 91 (JWT/TCU/ECU as well). With 17 inch wheels (heavier than stock I would think).

Fred...

[1992Q45A]

Cool.

94+s just arnt great drag cars. Even with a fortune in mods, they still can't get up to high 90s.

Watch my car run a 93 now :P

[PoorManQ45]

Ok, does anybody make a lightweight flywheel for the Q or one for any other car that would fit on the Q?

[PoorManQ45]

94+s just arnt great drag cars. Even with a fortune in mods, they still can't get up to high 90s.

Has anyone tried puting a drag type suspension on the Q? This would allow for a better weight transfer,as in stock form there is almost none.

Quote »Watch my car run a 93 now :P[/quote]

Now Ryan....do you seriously think that I can let you get away with that statement you just made and not comment on it

I guess we will have to renew an old east coast vs. west coast rival thingy and showup your west coastness what's up with my Q.......even if it did cost me a f_cken fortune in mods....I bet I still run harder than your sodium valved car with its two HP peaks

I want to see time slips first and then we can talk more....I have not seen any real time slips from any 90-93 Q's yet.

[AZhitman]

LOL - Go get 'em, Rob!

I think I might need to revive my time slip thread as well. As I recall, the ol' 95 cracked the mid-90's on pump gas with 18" chrome boat anchors on all four corners.

I don't think my 4.08 and my home-grown ram-air qualifies as a "fortune" in mods...

[AZhitman]

No need - Until you're losing traction at launch. Which few (if any) of us are...

Even if you did, it'd screw up the driveability.
