ok first of all i must apologize to everyone here. I been really busy with work and i just haven't had a chance to come check the forums or do my write up so i'm sorry~~
Anyway here it goes. CP-E finally finished all the tweeks they wanted on the downpipe. So i bolted the cat back back onto the down pipe. Now i may be getting different results because i also had my cars reflash done. Yes this means i now have the feared triple combo. CAI, DP, Cat back with the new flash. After starting up the car i noticed the tone had smoothed out a bit. This was to be expected seeing that all the sti guys i know with a dp and catback did the same thing. For the first few hundred miles i took it easy. I too was a little concerned about what MIGHT happen with the triple combo and the reflash. Checking my EGT gauge, everything was nominal. I was sitting around 1380-1420 degree F at normal crusing. My boost has been reading a consistent 17psi peak with a 15 psi settle(No boost creep) After about 200 miles of "normal" driving i started to get on the system. Flooring the car taking EGT temps up to 1490 degree F peak with a stable sitting point of 1380-1400 ish. (1510 is danger zone so the system is safe). Again there was no boost creep. My boost gauge read exactly what it has been reading since i got it on the car.
.....Heres what ya'll been waiting for....
When acclerating the system pushs HARD. I mean WOW. Accleration is very smooth and the car definately pushs me back into my seat. There is a little back fire time to time, but without a tune this is again to be expected. Exhaust tone is nice and deep and very smooth. The car acclerates like a dream. The turbo responds great! The triple combo setup definately redefines the car. The low tone growl of the exhaust in combination with the turbo spool and blow off valve, i've not only broken the necks of bystanders watching, but i break my neck when the car's g force pushs my head against the head rest. According to the AE scan tool i am pulling about .45 G's when acclerating. When I was running stock the car was pulling about .35 G's. (G = G force) I have been driving with the full triple setup for about 2 weeks. The combo of the 3 parts have about 2000 miles on it. I have yet to see any problems at all. The engine temps are all about the same as they were before. Also after the car hits about 4000 rpms, i feel a huge boost. (it almost reminds me of a primitive vtec) After 4000 the car pushs me back into my seat. I can continuously feel the car pull even at higher gears.
Just to make sure these gains weren't just in my head I had my friend with his G35 do a quick run with me.
I ran against his car before and after the turbo back install. We ran a total of 6 runs before and 6 runs after. Same road each time, with the same distance. Both days the atmosphere conditions were similar. The G35 has a titanium cat back exhast system cold air intake plenum spacer and tanabe sustec coilover damper system. The first 6 runs before the turbo back i would beat his car by about half a car length. After the turbo back exhaust i was getting about 3/4 almost a full car length. The G35 was the constant as his car had not changed. The turbo back smooths out everything in the mazdaspeed. From accleration to just straight power its all positives. I am working on taking a video of the exhaust system. Again i just have been swamped with work but i will get that done ASAP. The Sound is beautiful. The Power is great. And even with the Cold Air intake Down Pipe and Catback I have had No issues what-so-ever whether it is street crusing or pounding hard racing and aggressive driving.
