Has anyone done actual HP #'s on bolt on performance parts for the P5 ??

[canp5]

I am looking for actual performance gains for bolt on performance parts for a 2002 P5, not just the manufactures guess. I have an automatic that I want to get as much as I can out of with bolt on HP I have done the K&N CAI and NGK wires and looking into exhaust and header combos. So if anyone has any good results in performance gain with bolt on parts please let me know. Also thinking of pulley's,plugs and injectors.

Any and all info will be appreciated.
Thanks

not sure about numbers but all i have done to the engine is a SRI and i can feel a slight difference, my axleback is coming next week so ill be sure to let you know if i feel a difference with that

The only way to get a good measurable amount of performance out of these cars is to "bolt on" a turbo kit. Especially with an automatic...

Check the dyno section.

Haven't added up any numbers or done dyno but am also auto(sportronic). Did all lightened acc pulleys, UDP lightened crank pulley, 1.8 coils, p&p intake after removing VTCS, OBX header, hi flow catted midpipe, ss Magnaflow muffler catback, atf cooler, SRI with K&N filter, ZFR "long reach" plugs. Actually have an MPI Tuner with NA module, flying Miata voltage clamp, Innovate LC-1 wbo2 with AFR gauge & another OBX header with a 3rd bung for wbo2 sensor that I haven't gone crazy installing yet due to ecu harness hacking involved but that should control fuel mapping and timing. Not sure what that'll get me other than better, less rich AFRs and maybe small bump due to timing advance. When/if it gets that far I'd probably go ahead and spring for the FSZE cams and some adj cam gears that actually worked right to go with all that. Not sure I'd see more than 150-160hp with all that done vs. the 135 it's supposed to have stock at the crank, not whp.

I thought the fsze cams were supposed to had 15 to 20 hp to the wheels? Or is that just advertising bs

Going from 135 stock to maybe 160 or so with all the s*** listed would be taking the cams into consideration..........

I really doubt you see better than maybe 145. You definitely won't be 160 without boosting it

 

[tweety2300]

Wow that sucks I figured for 400 bucks you would get more than that out of the cams. but spending a grand to get 30ish hp to the flywheel is rediculous imo. for that you can find a mazdaspeed turbo kit with the intercooler and get what 175-180 give or take with slightly higher compression than the mazda speed proteges. There's a turbo in the fs section now for 300 plus 500 for a steedspeed manifold ebay intercooler is what 150-200 plus the many amounts of little stuff end up around 1200ish.plus automatic = no lag between shifts so actualy a little quicker than a 5spd but how strong are the automatic trans?

 

[Spiced MSP]

If you want decent gains, boost it. Find someone on here selling turbo parts from their protege and piece together a kit. With supporting mods and tuning, you will probably be happy with around 8-10 psi. Hell, even stock boost(with slight mods) for the mazdaspeed is enough to break the tires loose lol
Any questions, let me know

 

[tweety2300]

I have traction issues now as it is now and when it does get decent traction its wheel hops like a mofo. But as I already stated there's a kit for sale now for cheap. But I'm still new to this car and already relised it lags big time in the power department

 

[canp5]

WOW I was hoping to find some good info on bolt on HP and it looks to be gettting a turbo kit. So I guess I am just going to stop after getting an exhaust and header(still not sure what system is the best for the P5 any ideas ???) and start looking for a turbo.

Thanks

My shop will actually be doing a bolt on test early next year, since I havent really seen any serious threads about this issue. We will also be determing if the cheap obx/ebay products make power. We will be doing a baseline dyno on a stock motor other than an intake and mazdaspeed protege axle back. The 2nd dyno will consist of the following......

Ebay header
obx exhaust
pulleys
custom intake
pulleys
light weight flywheel
mp3 ecu

The final dyno we will add cams to the mix as it is the most labor intensive bolt on other than the flywheel. Look forward to seeing this thread early next year. Our main goal is to see if there is power in the cheap "bolt ons".

Should be interesting fox

Is there any possible way for you to test power gains for each individual part? Or would there be too much time and labor involved?I'm sure many people would be interested to see individual gains for each part, but your the one doing all the work so can't be too picky. Any idea as to when to all this will be done

Somebody could if they had a lot of free time, access to all those parts, and free/really-cheap access to a dyno. I'm guessing not many people around here can satisfy those 3 criteria.

 

[tweety2300]

Well he said his shop so that's the access to the dyno, he was already planing on using all the said parts so he has /will have, and then there's the time factor which I doubt he will have making you right but I was just asking and hoping he would be able to do it

The best bolt on performance pieces you can buy for our cars are suspension bits. The P5s engine does not respond to N/A mods at all really but if you put money in to springs, struts, rear sway bar, light wheels and summer tires, it will corner with the best of them.

Most people think of performance in a straight line when its actually more all around. Hell leave a P5 stock and take it to a SCCA auto-X event and it will do great in the stock class. You have to play to a cars strengths and our cars are made more for corners than anything else.

 

[tweety2300]

Ya but some peoples heads are made to be shoved into the head rest under wot not shaking it feeling embarrased when a prius passes u that's why I'm gona stay slow cause I'm not allowed to turbo but If I can get 150 whp out of it ill be happy atleast then it can get out of its own way. But we all know these cars are not meant for power and when they get power stuff breaks I mean how many people have blown a forged motor with a good tune? With higher compression pistons cams better tune and rebuilt head I think I should be good for 140-150 whp handle and look good

Tweety.....

My shop does not have a dyno. We are not "tuners" which is why we do not have a dyno. Granted we do a good bit of performance work, I choose to leave tuning to the real tuners out there. A good tune is the difference between reliable power and a blown motor. Moving on, I could dyno each part but on a car like the protege these mods do not perform at their best by themselves. So testing each part personally isnt worth the extra time and dyno fees. The good thing is the test im putting together is a "cheap" power test. So each can be had relatively cheap. As others have said these motors do not respond well to NA mods as far as numbers go. But if I can get the car to reponds better as in acceleration and throttle response that would be greatt! As far as making it fast.......haha look for boost.
