okay guys....curiousity has got me too so here I go. I have an appointment for several dyno all at different stages of my mods. The first dyno is Thursday morning with nothing done to the car. Just plain old bare bone stock well maintained car. Next week will be the dyno with 4.08, rail flush, throttle bottle cleaned, new fuel pump, etc...mostly just maintenance and cleaning issues. After this...dyno #3 will be with LevelTen transmission. Then finally will be dyno #4 with JWT ECU/TCU. This will solve it once and for all. By the way...I found a performance shop here in Miami that they say is one of about 20 shops in the country that can tune a car like they do as they have all these crazy gizmos and can tune a car with over 1,100+ rwhp. They said that they have every piece of tuning equipment available to modify all types of curves and the ECU. They were real interested in my car, but can't get me in for another 2 weeks and I want the facts on before and after. So after I get all the mods done I might pay them a visit to see really what all there gizmos can do, but they are real expensive $$. I don't really think much more can be done after I do all these mods as they were said that they new JWT and all the work they put into the tunning was really sound good tuning with reliability.
I know that there will be other parameters(air temp etc) that will affect the numbers, but at least we should see the whole pic.
With regards to the 90-93 neck snapping stuff....I have to agree with the post above as my 95 does not snap any necks but right at about 3,500 rpms the thing really just opens up and pulls very strong all the way to the redline. I can only hope that the 90-93 neck snapping is more due to the lower 1st & 2nd gear in the transmission compared to 94-96 transmission gears of which this will be eliminated after I get my 92 levelten transmission installed with the lower gears..I went with a 2,400 stall on it
295hp?
Great. The dyno's correction factor should take care of changes in ambient temperatures. I look forward to hearing the results.rsiwicki wrote:okay guys....curiousity has got me too so here I go.

My 95 doesn't have the same "urge" above 5K as my 93 did. It pulls to redline, but just doesn't feel as enthusiastic about doing it. Dennis posted something awhile back about how the different port shape affects high rpm horsepower, but I forget the details.

Did it occur to you there are too many uncontrolled variables between the base run and run 2 to determine which procedure resulted in what gain? It's expensive to thouroughly test every modification. Might try timings both ways on same road and correct for temperature and pressure.rsiwicki wrote: Just plain old bare bone stock well maintained car.

I already mentioned that there are "other parameters" that will affect the results, but that this will give us a general idea on the whole pic. If I only get say 5 hp + in the end...
then this is not significant...but if I get say 25+ hp then we should know that given all the "other parameters" that could affect the numbers, that there was at least a significant gain.
That is the main part I am trying to find out...Is there a real gain in HP with X, Y, Z, mods??? I am not looking for precise numbers on each mod, just an idea of the overall picture. And if in the end after all the mods I should be able to compare the first dyno runs (stock) to the last dyno runs and I hope to see a significant gain...say 25+rwhp or more. The runs on each way on a flat road are a great idea...but I am not Car & Driver nor have the time and resources to do such a measurement. I have worked out a deal at the local shop to do the runs for $60 each...using 4 separate dyno runs total will be about $240. To me $240 out of the total monies I am spending $$ to really know what mods can and can't do for a car whether it is this car or another car. I am having fun at this stuff as I have never modded a car before which is probably one of the best reasons behind doing all this crazy stuff. I also don't like to have questions in my mind on how much this or that really added to the overall pic. So the next time some transmission place tells me that they can increase the efficiency of power transfer, I will know if somebody is blowing smoke or telling me like it is. I am not out to prove anybody, company, or organization right or wrong with these dynos....I just want to be able to say to somebody on the street that I ran XX HP stock and now with all this stuff I run ZZ HP and I can tell you exactly what I think this mod and that mod does with a good indication of real numbers from a dyno versus hearsay.

RSI,
You have it right. Thanks for doing this, it's a big help. You're paving new ground here, and it's much appreciated.
EAGERLY awaiting your results
I have a free domain for work.. I am thinking about setting up a Q45 performance site.. general info.. available mods.. dyno numbers.. etc
Doesn't seem to be anything like that in existence..
Anyone have any recommendations on names?

Of course, but the problem is you will not know which particular modification is increasing, neutral to, or decreasing performance. Hence the suggestion for the timings between each step. If you only measure the all at once, you will never know if any of the modifications have a neutral or negative contribution, nor to what degree.__________________Brian1995 Q45 & Q45t & 2000 Q45rsiwicki wrote:That is the main part I am trying to find out...Is there a real gain in HP with X, Y, Z, mods???

Discover the power of the button!
okay guys....curiousity has got me too so here I go. I have an appointment for several dyno all at different stages of my mods.
I am just loving you guys! I'm willing to bet you'll see at least a 15 + hp dif with maybe a chance of 25 to 30 +. Too many braggards and company guys exagerate just a little too much sometimes and that ruins the true picture and actual performance of available products. Even if some mod does work well enough it's blown up too much and it becomes an actual dissapointment when you put it to the test. Straight forward is very good.
The fact that there are so many of us who are willing to test these things is a testament to how fun it actually is to drive and work on these cars with the limited funds most of us(me) actually have. I really can't wait to hear about your results as I have just started playing around with my 93 Q.
I intend to do some testing myself, but have to wait a bit to get my Q in shape. It's put on some miles before I bought it and needs to be really looked over before rubberizing my roads, but I'm so impressed already with what limited runs I've made.
Please keep us informed because of almost right behind you.

all right!!! I have another dyno guy like me to put these things to the test. Welcome redmanfx...and I welcome your support with the dyno of these mods. My first run will be Thursday morning before work....so I should be able to post results that afternoon. I am nervous so see what my car does as I have heard that even though all cars are built similar, the HP figures do vary between cars for some reason. I just hope that my car is not on the slow poke side of stock figures. I have never rode in another Q except mine so I have nothing to compare my car to.
I agree with you that many times these mods are overstated, but there are a few out there that are legitimate and probably best bet for true numbers is the JWT ECU. Just a look ahead type of thing for you.....the JWT ECU takes about 7 weeks to arrive from the time of order and they have a core exchange program where they charge you a core fee of $500??? Until you return your core to them that way there is no down time on your car. I did this and they don't charge your credit card until they actually ship the new ECU to you. Then you have about a week to switch them out and mail them back your OEM ECU. So if you are thinking that in about 8 weeks you want the ECU upgrade, then I would order now as they have not charged my credit card yet and it has been about 4 weeks since ordering.

Great! I was wondering about order time. Funny how all you need to do is look here and find it(or it finds you) I'm looking over and doing some maint on my transmission this weekend, so I'll get a good idea of how much money I'll have and what Mods I actually want. With the 93 I can't say enough how much of a surprise it was when foot met accelerator. I'll be keeping tabs..

redmanfx93 Q45a
If you go with the JWT, you should see 300 hp. This is a proven mod, over and over...
You know if Q45tech gives it a thumbs up, it's good to go.
Redman, if you are considering a level ten upgrade, you and I can order together and save $500...
Heh redman, I remember when I first drove my 91... I was like DAMN... then I raced my first m3, and it couldnt pull an INCH on me.. now that was trully great...
Ah and the svt cobra I raced on the I17.. who simply couldnt believe I owned his convertible on the freeway... his jaw dropped when I told him my car was bone stock.. that was great INDEED

I raced my friends 4 door 98 m3 on I95 two years ago one night from about 70 up to 125. We did a one lane run (single file) and I was ahead of him. He said that even though he was on my arse....he had it hammered the whole time. I had the knock sensor issue going on at that time and I can remember feeling the car miss all the way up to 125...really frustrating...especially when you had it to the dealer and they said that it was normal running for a car with 105K on it and that nothing was wrong. I told the head mechanic at the dealer where to stick it and took it up to Ft. Lauderdale...where even the service write rep diagnosed the problem right over the phone when I was telling him what was going on.
