10 psi safe???!!

Happy boy! (bicker) (upbum)

Umm....that's great badboy.....but 4356 is about what? 4-5 months worth of driving? Let's see where your car is in 5 years.

At any rate, I know the risk of boosting increases wear on your motor, I just wanted to see if anyone had any technical data on that. That way I can be picking up "my hoes" in five years and going strong.

I don't think I will have my car in 5 years from now. I get cars like every 2-3 years. But anyways I maintain my car at all times. I treat my car as if were my b****. I keep up on the oil and all other things that need to be maintained on it. I drive hard but I know my limits.

In that case.....G's up hoes down badboy. Keep the pedal to the floor and the bitches in your lap. Word.

Um...4300 = 4/5 months?

(hand)

I hit that driving since 4.26.03....

 

[TURBO3WAGON]

I have about 4600 in 2 months.

 

[SuperSpud]

Im at 2000 after 3 weeks.. ha ha ha ha I think my odometer is in Km or somthing...

 

[Maestrokneer]

Then you all just drive WAY to much! I based my calc on an average milage of 12,000/year, which I've heard is pretty standard.

Plus, I've had mine for a month and a half now and am only at 2100.

AZSpeed, If it was any other car, then I would up my fuel pressure. I got an A/F gauge, and it is always pegged at rich, unless im at idle. There should be no issues boosting to 10 PSI. I am, and have no issues as of yet, and I drve hard every day.

Agreed- my car gets taken to the rev limiter in first and second gear SEVERAL times a day and shifted at 6500 or so from there up (none of this "the MSP won't make power there"- it will and does once you let it breathe ). It has been driven like this at no less than 9 psi and as much as 11-13 psi (14 once, but that was a spike) EVERY SINGLE DAY since it had about 300 or so miles on it- it now has 6500 and I have had no issues with anything.. yes, only time will tell long term effects, but you mod a car, you drive it hard and you wear it out faster- no matter what kind of car it is .. If you want 100% reliable trouble free operation, stay stock- and even then it won't always work as planned .. there are some of us here with years of experience in building and maintaining turbo cars- we are the ones monitoring every little aspect of this car and how it responds to what. The rest of the guys are more than safe staying well behind how hard "we" are pushing our "test cars" .

I wouldn't recommend 9.5-10 psi on a bone stock car if you are the type to rip down the highway- the exhaust is too restrictive for that. It is safe for those who like to just jump on it for quick shots down the road and such. once the exhaust is done, then you will eliminate a huge restriction and a huge generator of cylinder pressure/heat/detonation .

2-3? Wow, you are in for the long haul- I am already looking for something else . I think I last 3-4 months before the ADD kicks in lol... I have honestly had at least 75 cars so far. About 20 of them were DSM's!!! I'll probably hang on to the MSP for a while, but it's replacement is hopefully coming shortly .

[yashooa]

Well Well Yankee Boeey.

Exhaust you say Joey? Cool thanks for the tip ma Brutha!
I'll keep it at 9lbs and only spank it on those "special" occasions.
Spank da car dat is...
No one likeS preignition WORD TO MA HOMIES!
Opposing wave fronts can ruin your poor little cast piston's day
I'm so cracked in a bad way.

I will just add this....

The MAZDASPEED I have greeted in my garage the past couple of mornings isn't the same one I purchased in January. This Mother ****** is POSSESSED!!!!!!!!!

I LOVE MY (HIGHER BOOST) MAZDASPEED!!! (k) (k) (k) (k) (k)

 

[RX-KEVIN]

I am running 10-11 psi daily, and have noticed a huge difference when I took the cat back section off. the key to more boost is more flow. The factory pipes just add low end and seriously limit high boost flow I managed a 14.6 10psi with stock exhaust and predict 14.4 with a mod that cost nothing

 

[Captain KRM P5]

As for 220 at the crank, my snowmobile can handle more than that .. That is a VERY conservative number. I know quite a few people with MSP's and P5's putting in excess of 240 to the wheels with no issues whatsoever.

The Speedvision WC Proteges (i.e. - Roger Foo's P5, Bonacorssi's ES) run about 230 horsepower with custom engine work and they have to be rebuilt every four races - what are they doing differently that thier engines wear out faster? That work and those parts are all done by Mazdaspeed. Also, if you and bunch of others know how to get 240 wheel horses from my Protege5's turbo, please let me know. I was running about 11 - 12 psi on my Garrett T3 w/intercooler setup when my bottom end gave out, snapped a rod and shattered a piston and blew four holes in the block. Running way too lean. Granted, my turbo is a completely different setup than the MS/Calloway setup, but I'd like that extra power as much as the next guy.

Not calling the BS flag, don't get me wrong, I'm just as curious as anyone else how to get around the ECU issues / fuel issues. I also don't want to see anyone blow up their engine like I did, so you'll find me tending to advise CAUTION The only person I was aware that was getting anywhere near that kind of power was SpoolinMP3, and he was running race gas and fuel mgmt.

A lot of race teams rebuild every so many races .. As for the motor not handling over 220 hp- you are stating that your car ran lean and popped and SpoolinMP3 was running race fuel and fuel mgmt to get his #'s.. That right there says the tuning will not handle over 220, not the actual engine .. The motor, while not the strongest or best candidatefor boost IMHO, is also not as frail as people make it seem. With proper tuning, timing, fuel, etc. the motor will hold up past what people say it will. It won't hold 500hp or anything, but it will hold up for what most here are going to do. You just have to keep it from detonating and hammering on the rods- they can't handle the additional stress .

On the MSP with it's less aggressive timing, over rich fuel condition and tiny paperweight of a turbo, 9-10 psi will not supply enough air to pop the motor. Just be sure to use premium fuel and keep the car in good tune- if the fuel filter starts to clog, that could be the end right there with any turbo car and getting 1 or 2 heat ranges colder on the plugs won't hurt either.
