IS F (2008-2014) :: PPE Equal Length - Long Tube Headers?
PPE Engineering has been getting lot's of inquires from us ISF owners about the feasibility of making an Equal Length Header for the ISF similar to the one they make for the RCF. Since I am a past customer, live nearby, have another vehicle and am a pretty nice guy they called and asked if I might be interested in having my car test fit for Equal Length Headers.
While discussing this with them, I suggested that if modified RCF Headers wouldn't fit, maybe they could accomplish the equal length task by using long tubes. Well, it seems that RCF headers will in fact fit in an ISF, and the headers they built for me were also Long Tube. How sweet is that? But, the EL, LT headers must be used with the PPE Exhaust due to the exit point of the collector.
I went for Dyno testing yesterday, and it appears I lost 7HP at the top end and gained only 1.5 lb ft of torque at the high end. I also gained grunt at the bottom. My Seat of the Pants tells me the car is faster.
I don't know why it ran out of breath at the high end. Nothing else has changed.

PPE Dual Mode Exhaust - With HiFlow Cats
Takeda Intake
As far as sound goes, in the cabin with the exhaust open, the drone remains in the same area (between 1900 and 2100 RPM) but is much lower in volume. I can now carry on a phone conversion (with bluetooth hands free) with the exhaust in the open position. The volume level does increase, however, when under acceleration through that RPM range.
Now the ISF does not have a lumpy engine by any means, but it idle with the old headers, the sound (both inside and outside the car) had a sort of lumpy growling quality to it. The sound is now very smooth, again inside and outside. The harmonics seemed to have changed.
Edit - My wheels and tires have changed. I'm now running RCF wheels with larger 295 vs 285 rears, so wheel weight is up a bit!

So.. Today coming back from work, I felt clucking sound from front wheel when going from 5-15mph. I even felt that when I had my left foot on the foot rest area. Its appeared during the driving from work to home and check whether if there is any rock or tree branch on tire or wheel but no...
So after 30mins later, went to gym and the the sound was completely gone.. Would it be because of bad wheel bearing or suspension or ball joint issue?

What is the bed length on a 2004 f-150 crew cab?
View 5 RepliesFord F-150 (2004-2008) :: How To Determine Overall Truck Length With VIN Number
My garage measures exactly 235" deep, and I would have to remove some shelving on the back wall to get it. I want a used F150 with an extended cab, and so due to the length restrictions, it needs to have a short bed.
One Used Truck dealer actually measured an F150 he had for sale, and it measured 228", which would have left 7" if I had bought his truck. So part of my question is if all F150's are the same length, do they vary by year, body style, etc..., but my main question is if it's possible to know the overall length of the truck just by having the VIN#.
Weeks ago, I found a particular "VIN Checker" website that gave me the length of one particular F150 based on the VIN#, but I didn't bother to save the VIN Checker website, and despite the fact that I've used several sites to check several trucks, the "overall length" specification has not been listed once, ever since.
So I don't know if there was something special about that particular site, or if the overall length spec is only available (via the VIN#) in certain years, on certain models, or what. So I'm asking.
The main reason is if I'm looking at a truck and I can get the VIN. Note I see other physical dimension specs all the time, width, etc... but length is the one that I DON'T see. I don't know if this is because the VIN checking websites don't have/can't get the information..
Ford F-150 (2004-2008) :: AC Compressor Bolt - Size And Length?
I went and fired up my ac today for the first time, and guess what no ac. So I crawl under the truck to check the compressor out, and guess what I find? The stupid face of the compressor had came loose and was sitting between my frame and the steering rack. Just glad it didn't fall off the truck, now I need to put it back on, but what size bolt. Looking for a spare compressor or know the size and length of the bolt?
View 7 RepliesBuick - LeSabre :: 2005 - Check Tire Pressure Light Is On - All Pressures Equal And Normal
The light has been coming on for the last couple of weeks. I can reset the light by pushing the dash button. On a 700 mile trip last weekend, I probably reset it half a dozen times. The tires are all at 30 PSIg. Two tire gauges agree. I don't know how the system works. I don't think there is a sensor in each wheel like some later cars have. I suspect it works off of ABS sensors and wheel revolutions. The ABS light is not on, nor has it been.
The right rear tire has been replaced with one of the same size, but a different brand. This issue started a month after that. Can that tire have a different revolution length per rotation and cause this issue?
Civic - Honda :: 2014 - Making Sounds When Accelerating
my brand new honda was recently involved in a really bad accident. It was in the shop for almost 2 months and had issues everywhere because I was t-boned. I just got it back a few weeks ago and recently it started to make a humming or ringing sound as i accelerate and start to slow down. You can even feel a slight vibration on my gas pedal and its making me very concerned since it was completely quiet prior to the accident. Thoughts? I would probably take it back to the shop that fixed it considering this would be their issue since they fixed it improperly and the length it took to fix was ridiculous.

I just had a new header installed (deletes first cat) and had my header back exhaust redone with high flow resonator and cat. As expected it eventually threw up my check engine light, I am assuming because the poor computer is utterly confused by what my 02 sensors are telling it. I was thinking tuning, but I am not sure where to find a tuner for the camry, or which tuners would work on the camry computer.

I recently started noticing that my engine sounds louder and rougher than usual. I have a 2014 GX with about 25K on it. I get about 800-900rpm on idle and about 1800-1900 when cruising 70-75 mph.
Engine sounding louder all of a sudden. No "check engine" sign pops up. I also took the car to the dealer and mechanic rode with me on surface streets and of course , everything looked normal to him.
Ford F-150 (2009-2014) :: Hard To Start Then Sounds Like Rocks In A Tin Can Upon Accelerating
Ok, heres my issue. '11 crew cab f150, 4x4 5.0L. 108K miles Yesterday got in my truck to leave and it would crank, idle very rough with RPMs fluctuating then die. Did this several times til it stayed cranked long enough for me to press the accelerator to keep it cranked. Headed out down the road and it drove fine. Then upon accelerating I'd hear a noise like rocks in a tin can. Every time I accelerated it would do this. Drove to a mechanic. He drove it, heard it and told me to bring it back today because he was covered up. The rattle sound is similar to valves ticking, but worse.
I got up under it and looked for loose skid plates and loose exhaust components and could find nothing. Took it for another drive,engaged the 4x4 to 4H, drove it for a minute, went back to 2H and the sound was all but gone. Went ahead and filled up with premium gas. (had an 89 ranger that would only run on premium so thought i'd try it) Drove home. the noise was gone. Got up this morning. The truck hesitated to start. took three tries, then fired up normally. then drove it....no problems. no noise, everything normal. Don't wanna take it to the mechanic, if there is no apparent problem now. What's going on with my truck?
Ford F-150 (2009-2014) :: Sounds So Grumpy At Takeoff And Then So Quiet At Speed
I've been wondering why my 5.4L sounds so grumpy at take off and then so quiet at speed.
I'm assuming this ain't factory? Looks like a flowmaster but can't find any markings on it.
I want to get dual exhaust (yes I like the look) but can't figure if I want Magnaflow or Flowmaster.
What I'm looking for is performance (is there even such a thing--rhetorical) and pure-wood-developing raw rumbling noise! Not the kind of noise but the kind that if you want to pop the throttle a bit you let the awesome guy next to you know that this truck ain't no slum.
I'm trying to figure out tips and placement-- I'm thinking straight back is the best bet?
Celica :: Distributor Mounting Bolt Length?
how long should the bolts be that mount the distributor to the (non-california) 5sfe? I'm putting my car back together (finally) and the only bolts from my pile that fit are one that is too long, and two that are only a couple threads longer than the width of the distributor flange. simplest conclusion is that the latter are the bolts that were there, but does that seem right?

Ford F-150 (2009-2014) :: 2013 Ecoboost Sounds Like A Diesel On Cold Start
I've got a 2013 ecoboost with 31,000 mile on it. Generally it's been good but at 30,000 mile it started sounding like a diesel on cold starts. Usually after sitting overnight the first start rattles like a 6.0 liter diesel for about 3-8 seconds then it's quiet. It won't do it again all day usually. The dealer says there's no codes so everything it all good. It never did this until I hit 30,000 miles.
