First of, I did some stat logging from my COBB AP Tuner. I watched my boost temperatures for about 2 days. Here is what I logged:
Morning: 68 degrees. At 65mph+ I stayed between 85 and 92 degrees. At idle I was around 115 degrees. This was a 20 minute drive with no traffic on 95 south. I data logged a third gear pull and went from 100 degrees at 3500 rpm to 87.8 at 6077 rpm back to 96.8 at 6700 rpms.
Afternoon: 80 degrees. Did a couple 3rd gear pulls as I was fine tuning my COBB AccessPort. My Boost Air Temp was at 129 degrees at idle and down to 114.8 degrees under boost.
Morning: 70 degrees. At highway speeds it was reading a steady 91 degrees. At Idle it was reading at 120 degrees. I did a 3rd gear datalog again and temps ranged from 96 to 102 during the pull from 3000 to 6700 RPMs.
Afternoon: 82 degrees. Did a couple 3rd gear pulls while monitoring with the COBB AccessPort. My Boost Air Temp was at 131 degrees at idle and down to 116 degrees under boost on average.
After the install of the SURE Motorsports’ TIG I did notice a drop in boost temperatures. It was not drastic but it did drop a bit. The TIG installation I did was the single intake manifold TIG and Throttle Body TIG, as well as, the coolant bypass on the throttle body.
Morning: 72 degrees. This morning I drove the car normal with my typical commute to work. Under normal throttle, barely entering closed loop or going Wide-Open-Throttle (WOT). My temperatures stayed around 85-90 degrees. At idle my temperatures stayed at about 106 degrees.
Afternoon: 86 degrees. I logged a couple pulls in 2nd and 3rd gear. Both times the temperatures stayed between 98 and 104 degrees.
Believe it or not the temperatures were exactly the same and with my logs and watching my COBB AccessPort, the readings were the same within a degree or 2 of variation.
Conclusion:So after about 2 weeks of watching my boost temperatures, before and after installation, I have confirmed that the SURE Motorsport TIGs do, in fact, help lower boost temperatures. By separating the intake manifold from the block and separating the throttle body from the intake manifold the SURE TIGs dissipate heat transfers throughout the engine. While I had the front of my engine opened up I also routed the coolant lines away from the throttle body. See the SURE TIG installation article and the Coolant Bypass DIY . Since coolant temperatures get to 180-220 degrees and Mazda runs coolant through the top of the throttle body, I did this. Because ever little bit will help!
This modification has lowered my boost temperatures by about 15 degrees at Idle and 10 degrees under normal driving conditions and about 5 degrees at WOT. It also reduced Knocking in my engine from 3000-4000 RPMs without adjusting my tune. You may be asking, “Why so little at WOT”? Think about how fast the air is moving through your engine at this point. The only way to lower temperatures drastically at WOT is via an upgraded Top-Mounted Inter Cooler (TMIC) or Front-Mount Inter Cooler (FMIC). However, the TIGs will help keep the air cooler throughout it’s travels!
5 of 5
Even though the temperature didn’t significantly reduce in WOT I still give this product a 5 of 5 because of 2 things. First, The quality is top notch. The SURE TIGs are virgin grade PTFE -400°F up to 500°F and is a reusable gasket. Re-usability is a bonus! Second, Temperatures did reduce. It did exactly what it was suppose to do and if I were to add the second gasket to the intake manifold it would be even more significant. Also, you do not need a lift to do the installation. If you are mechanically inclined this installation should take no more than 2-3 hours max. If you don’t include engine cool down time!
So I decided to try out some octane boost and see if I noticed a difference in performance. In my previous Mazdaspeed Protégé it made a great deal of difference due to all the mods, however my current 2010 Mazdaspeed 3 is bone stock currently. So while I was looking for electrical tape at the CVS I came across the bottle of octane boost by Gummout. For $2.67, less than a tank of gas, I decided to pick up a bottle and see what I could notice if anything.
Last night I had to fill up (The instructions say to wait until the tank is low and use when you fill up) and I dumped in a bottle and added 11 gallons of 93 octane and drove off. I had a 45 mile drive home at this point which is good for testing this out!
So I drive normal and got the good old Butt Dyno ready for about 10-15 minutes to get all the gas to cycle through and make sure I am getting the “good stuff”. I hit the entrance ramp from 665 to 97 north heading back to Baltimore and floor it to merge in.
The Butt Dyno then tells me the following:
- Acceleration is smooth and powerful.
- Instant response from the gas pedal to the wheels
- RMPs creep up quicker and much smoother
- Getting to higher speeds quicker
All-in-all I can say that the octane Boost is actually noticeable. Just to make sure though, I plan on not adding any to the next tank and then adding it again to the tank after that. The major inaccuracy of the Butt Dyno is mind over matter so I want to be sure and by rotating octane boost a few times I should be able to tell if my mind is playing tricks on me for sure.
So is octane boost worth it with the 2010 Mazdaspeed 3. For less than a tank of gas and keeping that RPM curve steady I say YES. Maybe not something I would use every fill up but definitely will use it for nice days with some “spirited driving” or at the track.
2010 Mazdaspeed 3 + octane Boost = smooth operator!
