Those times you posted were with a g-tech, correct?
Yes Adrian, those times were with a Gtech. However I found it to be within 1-2 tenths when i took my car to the strip when it was stock (on the 15's LOL)

I ordered 235/40/18 on Bridgestone Potenza S-01 Pole Position. Slightly wider and lower profile.

lower profile tires with less overall diameter is not going to give you better traction, you shoulda have went with a larger over diameter and thicker sidewall. or just get some drag radials.

On 18x8" wheels you can fit 245/35-18 tires no problem. On 18x8.5" wheels that goes up to 255/40-18.

I talked to tirerack about those tires a while ago. They claim they are pretty sticky and you should definitely hook up with them. But I think I'm going to go with the Nitto 555's since they're alot cheaper and are supposed to be pretty sticky as well.

I just put on some Nitto 555 245/40 and am extremely happy with them.

dicounttiredirect.com has them for $134, with free shipping. I was all over that!

Hey I started my car!!! It was a fuse LOL. It is running great. I did 5.2 from 0-60 mph and 13.6 1/4 mile before the interceptor. I think the car is able to do 4.8 and 13.2 with the interceptor. THe only thing is that I am losing all my traction in lower gears. I just ordered a set of Bridgestone Potenza S-01 Pole Position. WHen I install them I will let you guys know what it is able to do. I will try to dyno soon, I am just waiting for the 02 sensor from Mazsport. My hope is that I will be on dyno early next week.
Hey dude from calgary, as soon as the roads clear gimme a call so we can go for a ride.

My car is peaking at 15 psi (1.1 Bar) not holding it constant. It holds about 0.85 bar after the peak (around 12.5-13 psi)

Will try to post that video soon. Anybody knows how to post it??? Thanks
Im originally from Caracas (California del Norte) I'm living in Miami now. Lemme ask you, how come you didnt go with the 245/40s?

Dont want it to look too bulky on the wheels.
I think the 235 with the soft bridgestone rubber should be sticky enough to give me good traction.

I'm sorry but whoever told you that the 555's are good tires are wrong. I have driven them around Streets of Willow and they are not very good track/sticky tires. I'm sure they are decent street tires, but the Falken Azenis RT-615, Toyo T1S/T1R, KDW's, etc. are all way better tires. Noe hating on anybody, but if you have a chance spend a bit more, get a better tire, or get another line in the Nitto brand. The 555's are marginal, old design tires. I was at the LA Autoshow recently & Nitto has a new line coming out.

Received, thanks!! I will be installing it early next week. Going to dyno on tuesday.
Looking fwd for my results. I think I can be putting down a bit more than 300 HP to the wheels.

Beers!!!

Dyno

Hello guys,
My apologies for not writing yesterday. I was all the time in the phone with Scott (mazsport) while my car was being dynoed. My car seemed to be good the first run at low boost, but then after the first run something changed. It seemed to have a problem when it reached 6,000 rpm. After the first run the a/f ratio was good until 6K then it suddenly went 14,15 and on and on. I decided to stop the runs at 6K rpm at the lowest boost possible to avoid engine damage. Scott told us that the fuel pump might be the problem, we went to the mazda dealer and they were unable to measure the fuel pressure. (Sometimes I wonder how they did to produce such a good car with so inefficient people). We also tried another O2 Sensor and the same results. We installed Scott 02 sensor and same result (By the way, thanks Scott, the o2 sensor works great) I really recommend this product. Now the fun part begins. After spending 4 hours on the Dyno (I was charged the full 4 hrs even though we spent like 2 hours just looking at things in the car for possible cause), we decided to take the car to the mazda dealer (you know that part already) and then park it at home. I felt sick, I was so pissed off LOL. Then something comes up to our mind (a friend and me), we did some thinking about this and we figured out that I had run the car around almost 1 year with the turbo on it. That is the equivalent of, assuming 1 hour of driving a day, I had ran the car for around 350 hrs with the kit on it. What was the chance of something getting damaged on the dyno? Well you can do the math and that is 2 hrs on the dyno over 350 hours of running time, 2/350= 0.57% ! Umm that does not sound like too feasible. Therefore we came up with the idea of testing the car with Scott's o2 sensor and a laptop on the street. Surprise!!!!!! The car was all the time in the 11's and only couple of spots where it touched low 12's and back to 11's! What a surprise. We kept putting up the boost until we reached 11 psi constant with a peak of 14 psi and we found out that it was on the mid 11's all the way to 7K and then back to mid to high 10's from 7K to 9K.
I was happy even though i had to pay 340$ in the dyno. I called the guy this morning and we made an appointment for 5 pm (ET) to do a couple of run WITHOUT PLUGGING ANY O2 SENSOR!!!.
I will have the results in about 3-4 hrs. I will post today later.

Sorry for the delay.

Dyno Results

Hello everyone!
I just came back from the dyno. Power does not seem to be high, I was actually expecting some more. I only got 247 WHP. Torque is very good, we got 242 FT/lbs.
The most gain compared to the emanage was torque. It was at 215 before and now we are sitting at 241. Horsepower stayed the same.
Now the thing is, when i hit 14 PSI it is very early and there is when the torque has a big jump, however HP is still climbing. By the time HP peaks then I am down to 6 psi because the turbo runs out of air...

I am not dissapointed considering the huge gain in torque I had with the interceptor. And believe me, Horsepower you will need when u reach 120+ MPH, what launches the car fast and get u out of corners is the torque. Therefore I can say I prefer a car with 242 torque and 247 HP than a car with 210 Torque and 290 HP. Just my 2 cents.

Here are the 2 graphs. The first one is the run by itself, the second one is comparing to my best run with the 7Psi (like it was with the emanage).
So therefore we can say that the second graph shows what the interceptor was able to accomplish against the e-manage. Totally worth it. Thumbs up Scott.

a FIFTY whp gain is nothing to scoff at... Very nice!

Do you not run the car to 8k on the dyno? I think i'd miss losing that much of available rpm.
