no offence taken here, no worries.

based off of "stock" (like cattle) where the oil comes from/made from, i would say no one has anything over Redline's polyol-ester blend besides Motul; its an almost pure synthetic. also with the insanely high numbers of micro lubricants in Redline (molybdenum, phosphorus, and zinc) i doubt subi is any better and i doubt they even match. throwing a bearing with all 3 of them in high numbers you'd really have to screw up somewhere! i dont know your friends weight but i can say 100% throwing a bearing wasnt due to a heavier weight in an evo, stock or modified, unless it was gear oil. 400, 500, 600+ hp evo's i can promise dont run a factory weight when racing.

weight is a broad spectrum for temps and what the motor can handle. the biggest danger one could be in is a heavier weight on start up like a 10w, 20w etc if its to cold. once hot the motor is fine running a grade or 2 higher. my motor wasnt meant to increase power by 60% per cylinder! the slightly heavier weight performs a hell of a lot better when racing and increased cylinder temps. the last thing you want is pre-mature break down and your oil to run like water with 420bph going around a track. most guys even use a 0w40-0w50 when racing. id say every person of knowledge on nasioc runs a 40 weight.

biggest reasons for spun bearings- old/dirty oil, low oil, beating on a cold motor (oil you do have isnt hot enough to get into the space and let it nicely spin), worn out from abuse, clearance issues, vibration (un-balanced), over revving stretches the rod and the bearing spins out, coolant or gas in oil lowering viscosity, or to much boost/power crushing or squashing the bearings during the lift or fall of the rods. some of these dont apply to the main bearings.

decided to do my 5th grill tonight. i dont know if ill ever get a true functioning rear diffuser so i wanted to get rid of the rear parachute we call a bumper. now looking under the car the spare tire compartment does have a 1" lip coming off of it at an angle. this is so air hits the lip and gets blasted under the bumper and not up into the bumper. the problem is a ton of air still gets up in there from the sides and everywhere else. and i know this because its very dirty in there, lots of dirty water splashes from one side of the bumper to the other.

now im hoping this acts to let some of the air escape and not create so much drag. there's no way to measure this but i think it looks good it better than nothing.

You take your beast to get dyno'd yet?

BTW... I like the grills.

yes, i talked a little about it on page 15 and 16.

this is the current numbers and tune thats on the car with the exhaust cutout closed. 21ish psi tapering to 16.5psi and 23 degrees up top. this summer with better fuel i hope for maybe 23-24psi tapering to 16.5psi but with another 1-3 degrees of timing. that should crush the 400TQ mark and hopfully put me into a nice 340's HP range.

You should try out virtual dyno too... It's kind of my new favorite vs airboy as it's so much easier to use.

Here ya go. Give it a try. I've been using it for a few months now. Really cool, and extremely accurate. I've talked to several people tuned on a Mustang and a DynoJet who were within 10 HP when they put their runs in Virtual Dyno.

I love aggression!

finally got the lip i always wanted. i dont know what it is about HT Auto in the UK but i love the look of their stuff! problem is they are so expensive, specially because of shipping. well...now they have a US dealer finally. the lip shipped was almost $60 cheaper than its ever been before.

the fit and supplies and finish are amazing!! its like a OEM piece. all the holes are pre-drilled and 6 or 7 of them use the OEM type plastic pop rivet things that hold our bumpers to the car and those holes use the OEM holes. that means no aligning yourself! just pop them in and your done! simple as can be. they also come with 7 washers, nuts and bolts to drill into your bumper if you want to really make it secure and close off any gaps you see.

and to boot i hope it provides some down force from its down turned angle. what i think im going to do now is make an aluminium skid guard/front splitter kind of thing. i want the air flow under the car to act like a race car since ill be tracking one day. basically from the lip to the front axle will be a solid plate smooth as a babies butt. im sure ill use more then 3 mounting locations but ill start off using the 3 OEM mounting locations for the OEM under tray. i will just built it in sections and add long hollow tubes and then get very long 12mm bolts to hold it on. i hope the pictures explain what this will look like!

hmmm, i tired it out and it is easier but my numbers are all off. its saying im making HP till 6500rpm which i know isnt possible and that my HP is a lot higher than my TQ and we know thats not true. the 2.5 motor with under 400-500hp will always make a lot more TQ then HP.

so i decided to go a different route with the current motor set up. someone showed me some interesting things about blow through i never seen before. i knew the MAF volts, g/sec, boost and AFR were all a little wacky from it but i didnt know how much. im still not convinced that anything was dangerous because the car ran like a dream!! but because im OCD i needed everything to be perfect and smooth!!

so today i swapped my blow through 3" MAF housing over to my CAI and added a large nipple to my TXS RFL BOV and a spot on the CAI. i still need to paint and re-shorten my MAF wire harness. but the install went ok and i like the way it turned out.

so far we have just been working on the MAF scaling since it was setup for BT and now its a 73mm big CAI. tomorrow i will be doing some WOT runs hopefully and we will see if i gain/lose any power. one thing i do know for sure is the maps will look 100 times better!!

here is my boost, my AFR and engine load, and MAF volts







here is what a normal draw through setups should look like, big difference!

so i been looking into brake kits for the track. there are a lot out there and companies like Wilwood have about 30 calipers and all are used for something different. after lots of reading i decided to go with a W6A with a stainless steel piston vs their more expensive Thermlock caliper. these things are massive and they are supposed to be paired with a 14" by 1.25" rotor! the OEM 12" rotor by 1" i believe is very small and weighs in at 17lbs. i havnt decided if i want to use their rotor which is a lot of money or go with a centric blanks. the issue with the centric is ill have to find a car that runs the same size. if i do go with their set up the total weight for the caliper, hat and rotor will only be 27lbs. the OEM setup is 30lbs! its insane you get that big of a kit and its lighter. of course if i go with the centrics its gain at least 5lbs and maybe more.

Hey Syno, why shorten the MAF harness?

Because I added 3 feet and just used wire. The OEM wire is shielded so I need to put it back to regular length and shield it just incase it gets bad readings.
