13.3 on 116 - Praise me

[kwiktsi]

I didn't see any hoses cracked or split. I did however spill a lot of hot coolant on the hoses about 2 hours before this. I wonder if that made them brittle?? Also, What are you using to avoid hitting the boost cut and how is thestock ignition hot enough to burn up 116octane??

I am using the other thread now too, bu tI'll reply to this one here instead-

I can't see the AF making them brittle, but read my post about the headgasket possibility.

As for boost cut, I am using my "prototype" FCD unit. It has only hit cut so far at 21 psi when it was in the 60's. Other than that, I have not hit cut at all..

I am having no fuel problems at all running the 116 octane. The stock ignitions aren't too bad- they are stronger than the DSM ignitions IMHO- the DSM's would blow the spark out at anything over .028 gap with higher boost!!! Blow it out at .035 at stock boost with slightly used wires!!! I have had no misfire issues, detonation, nothing...

wait a second...
Are you serious? Have you ever taken this car to 21psi of boost????????????????
Still holding stock pistons and rods?
nahhh

yaahhhh .

stock motor- 6800 miles, 116 sunoco, BKR7E plugs, 21 psi- holds for about 2 seconds and drops to about 17-18 until almost redline, then drops to about 16. I have been running it between 18-20 psi for 3 days now. No less than 16. And I am almost ALWAYS jumping on it.. That's why I was asking what plugs you were using in the other thread. I wonder if it is detonation more than HP causing the failures. And to think, an hour ago all I was worried about was my stock IC pipes being on borrowed time .

joe I think I am in the same boat as you, I pound on my car almost daily at 12-13 psi and it feels like the fuel curve is still too rich

That is why I did the FP hack- you know the one you knocked in another thread .. I kind of feel bad that I bashed you for it now because you are being cool here ...

It is too rich still. BTW- what plugs are you running on your car? That psi is pushing it on stock plugs- the rich mixture might be the only thing saving you .. It may be OK on a hot day, but be careful when it cools to 60's or so, you will detonate there...
Joe
Ps- see- another abused, boosted MSP holding up . That is why I feel there was another cause for this besides a weak motor like people claim...

hey, kwiktsi
if this looks like a hijack....sorry

about those plugs...(dont know crap about it)
do I have to gap them, do they come pregaped.
tell me about them
I dont remember which ones came with my spool kit, I just took them out of the box and installed them. WIll check the site

I am running mine at .032 and they were right on the money out of the box, but I ALWAYS (ok, sometimes I slack off ) check them before installing them...

They are NGK copper plugs, #7 heat range. Stock are # 6 and platinum- hotter plug plus platinum makes it even hotter- plus it tends to glow and cause pre-ignition (detonation) beause it will fire even without spark once it does glow.. Not a good choice for turbo cars... The plug # is BKR7E and the "stock" # (what most stores go by) is 6097. I was going to wait a few days to post the info so I could try to burn the rest of the race fuel out and try them on just pump to see if it raised my boost/detonation limit and by how much, but either way, it will only help and not hurt..

OK something here doesnt sound right.
Please dont flame but some things i need to hear.
The 60 series wheel??
you all mention the turbine. the wheel is a compressor upgrade not TURBINE.
First of all WHAT turbo do you have EXACTLY?
What kind of injectors?550cc?
Greddy is controlling them at idle?
NO IGNITION control. The stock MAF bottoms out at 5.0 volts. I would like to see how your bypassing this with a larger compressor pushing a more dense mixture thru the motor at a lower rpm.

Do you have pictures of your setup?
Forget the slips i want to see the actual hardware.

Thank you in advance.

you could be righ about pushing 400hp on stock internals we will never know without testing:

I may try it with the piggyback of course, lets see ho good they are.

Mazda says 300HP then rods will bend, but maybe we can push that to 400 with good race fuel and timing retard, this way we will not need more PSIs than needed.

I say, tune the car for 15psi and stay there, tune and continue tunning and maybe you will get more HP from 15psi than anyother with 20psi without proper tuning.

Thats what Im going to do, but at 10psi

You will NEVER run 400hp on the stock motor. NOW if you increase the VE of the motor then you will come close. THE manifold and head have to be ported and polished. The rods cannot take high revs from a F/I vehicle. Trust me i learned the hard way and have gone with forged internals. Timing retard to an extreme is NO GOOD. When you want to run safely on pump gas though for the street that is your only option. WE retard timing on F/I vehicles because the peak cylinder pressures developed under boost at different RPM's need to happen ATDC. We retard the entire proccess to prevent detonation. Of course with race gas you dont have to be so aggressive in the retard department. The problem there is that the rods CANNOT TAKE the added inertial loads from race gas and timing lead for high RPM's. with proper engine management i can beleive 300-325 HP MAX and thats pushing it. Now the tranny she needs some TLC

Oh yeah , one more thing.
you have pistons and rods upgraded?
Were they made to any specific specs?
what rods are they ? who made them?
when did you rebiuld the motor? Have you posted about the rebuild before?

Sorry for all the questions but i havent seen a built MSP yet. They are still relatively new i just figured you would have come on here when you started the project to let everyone know that you built this beast. Also with all that work , time and money spent why didnt you go with some type of engine management for ignition. With all that work the numbers dont seem to add up quite well for 119mph. Maybe 106 max at that speed. Plus nitrous? On the motor without ignition and at that boost level??
What is your static compression on the pistons you ordered?????


thank you again in advance

Hey Joe, not trying to jinx you or anything, but this is my thread about blown motors. I'm pretty sure you don't want to start having all of your conversations in this thread!!

Hehe- good point. Guys, PM me from now on .

on a similar note, whats the estimated time it will take mazda to fix my car?

Guys no offense or anything but on the other page i have some valid questions i ould like answered from kinetix.

so whats up dude. get me some answers man
( for kinetix)

 

[GOTZOOM?]

When I use race fuel(116) do I need to empty the tank, or can I mix with say 1/8 tank of pump fuel.

 

[mygreenmazda]

I've read the whole thread and I was wondering if somebody has actually seen the car.

 

[perfworks]

i guess this guy will never answer my questions.
