cheap tranny modd???

Here are my driving results... rpm's at 60 mph in all cases:
2nd gear: 6500
3rd gear: 4.5-4.6K
4th gear: 3.3-3.4K
5th gear 2.5-2.6K

Probably runs high 12's low 13's.. No idea really...

Assuming you're still running 261whp, you're looking at mid to high 13's at best on street tires, etc. However from a roll, you'll absolutely embarass evos and STis.

I'm running closer to 290-300 now... up a couple of psi... and not at 101 degrees ambient and on my 29th dyno pull... hence my low 13 idea... but that also assumes I can drive... and considering how terrible my 1-2 shift is and that I won't force it.. we'll call it a high 13's low 14's run .

I got word back from my dealer contact... he confirmed there is NO part number change or break for any 2001+ 2.0L Protege transmission including for MSP's.

2nd gear: 6500
3rd gear: 4.5-4.6K
4th gear: 3.3-3.4K
5th gear 2.5-2.6K

Calculations based on Protege FAQ results:
2nd: 6200
3rd: 4400
4th: 3300
5th: 2500


SOOO.... other than something a little off with 2nd and 3rd (probably too fast or slow on my part... hard to get that speedo dead on sometimes) I got basically exact matches based on gear ratio.

i can drive very well down the track..im not going to lie. i need to work on my reaction time. but other then that..i can rip up some cars..i cant wiat to figure out everythign w/ my motor/turbo..i hope i can pull something..btw..you said something about 101ambient..what is that? and when are you going to price me up that stuff we spoke about earlier?also, i think i am going to get a custom gear set/the final drive gear..what do you suggest on that?

I'm at my day job... so I don't have enough time right now to do the full quote for you as that takes some time sitting down... I'll have it this evening or tomorrow... keep in mind you actually hear from me within 24 hours time which isn't the norm with vendors on here... but I am working on it...

101 ambient means the dyno room temperature was 101F ambient temperature... dynoing on a 100+ degree day basically.. and I was on my 29th consecutive dyno pull with only one 10 minute cool down that was done around the 18th run... so I was VERY heat soaked... so my timing was pulling back, my intercooler was useless etc.. and on top of that.. while I call it a 13 psi run... the boost was falling off and I was really only holding about 12.5 through most of the run... so needless to say the car puts out..

For the custom gears. Get them from MPNick.. he's got an awesome set and I highly recommend them... it's 2800 for the full 5 gears in whatever ratio and cut style you want plus new shafts and forks and the like... very impressive!

 

[Kooldino]

So here are the results from the pics I took at lunch.

60mph in 2nd gear @ 7000rpm, which is exactly what I previously calculated using the gear ratios for the G5/G15M-R from that website.

This also shows that the tach is accurate, since 7000rpm is what we see @ 60mph, as predicted.

That's a far cry from the 6200rpm that the calculations show using your ratios, Steve. For the ratios you used to be correct, my tach would have to be off by 800rpm.

well, as long as i can go faster in top speed, sounds good to me. but for sure, you are saying on our stock tranny/gear w/e...with enough power we can go above and beyond the needle? to like 160mph?

 

[Kooldino]

Here are my driving results... rpm's at 60 mph in all cases:
2nd gear: 6500
3rd gear: 4.5-4.6K
4th gear: 3.3-3.4K

For some reason my phone isn't sending the rest of my pics to my email, but I'll post those as I get them.

However, even with your setup, 60mph at 6500rpm is still 300rpm past what it should be with your gear ratio...and that's with your supposed "more accurate" tach.

(confused)(shrug)

Yeah.. but keep in mind that in 2nd gear if I'm even 2 mph off I'm going to get a massive difference in rpm's.... (63mph in that same gear yield 6500 rpm's... so 3 mph reading error and I'm there no problem) and since it was twitching trying to read in 2nd gear anyway so I could easily be off (mine twitches because of what I did with the speedo gear on the LSD).

I'm have a bone stock MP3 transmission in my car right now... so we need to reconcile the results between these two... my bet is that your speedo is biased high like a lot of the Protege's I've seen.

 

[Kooldino]

Since the pics aren't sending, I can get a close # by viewing the pic on my cell phone...

4th gear looks like 3900rpm
5th gear looks like 3000rpm

 

[TurfBurn]

Yes with our stock car we can hit 163 based on the ratio calculations... and you'll likely die before you actually get there anyway regardless of power... (I doubt the car can hold together for it from an aero/heat/suspension/steering/tires standpoint.

5th gear looks like 3000rpm

So you are turning exactly 500 rpm's higher than me in every gear... but turning the same ratios...

well Z rated tires are rated to 180mph i think..or something..and when i was cruising at 137 not going any higher(no power) it had no problems with rocking or anything..im lowering the car with the stock msp struts and tein ss springs.. but the heat, shouldnt the radiator/intercooler be able to do the trick to keep it cool? even if i got the tranny cooler or something..and the steering..i just have no clue how to deal with that

137 and 160 are hugely different even if they are only 20 mph apart roughly..

heat i mean valve and exhaust heat... not radiator heat... that much load and rpm's and the EGT's will be insane (I've driven mine up to a hair over 900C and I usually cruise on the highway at around 690C)

But to be as off as 6200rpm to 7000rpm in that gear, you'd have to be a full 7mph too low according to the speedo.

That's entirely possible, but 800rpm too high? That just sounds like too big of a margin of error. That's around 12% too high.

 

[TurfBurn]

using that website that you quoted here are the rpms at 60 mph
2nd: 6900
3rd: 4400
4th: 3450
5th: 2800

hmm..is there a way to keep that kinda heat down? and when you are talking about that heat, how do you see that heat?

Remember.. I told you that my buddy with a stock P5 with ABS (so not using a speedo gear anymoer) runs about 7 mph higher than me at all times... I clock against radar guns as being basically dead on as well... and I check out dead even against my truck as well.
