Yep. I'd say this is what I'm waiting for before picking up the Grimspeed package. Let's get this show on the road!

Is he getting both the IM and the TBS to test?

Sounds to me like he is only getting the TBS which isn't a bad thing because if I get anything, most likely it will just be the TBS until I see that the IM spacers do something more for the trouble of installing them.

SilverSubie2.5 · 02-13-2008, 05:44 PM

I'm pretty sure he is just getting the TBS. For most people, it has been the other way around. That is, getting the IM spacer and not the TBS, because the IM spacer does work. There is no questioning that the IM spacer significantly reduces IM temps, which will equal out to a small power gain. And from what I've read, installing them isn't TOO much hassle. More work that the TBS, but still 45 min-1 hour.

My thoughts are if I drive normal and the environmental conditions improve.... I quite possibly could see more improvement.

The consensus is that the people who ACTUALLY have a TBS do like the product regardless of what those who do not have one blog. No complaints yet.

Finally, thanks to Group A for stepping up to the plate - Respect.

this is kinda a threadjack, but its about miliage so its distantly relevant to TBS's. Anyway, i have a 07 2.5i and i use 87 gas no ethanol and i get 340 miles a tank on avg. I dont drive like a maniac all the time, but i def do drive hard more than enough. Just wondering what could account for such a huge difference in mpg's?

Mix of city/highway, location (FL vs. Omaha), how much idling he does ('cause its cold out), tire pressures... for that matter, tires, how hard you flog it, etc.

Personally I get ~260 a tank, straight city with a good deal of flogging.

RaceFaceXC · 02-13-2008, 10:05 PM

mines all city too, my highway mileage is horrible. the 06's have a 15.5 gallon tank? i keep a close check on my tires but i have pretty mild weather. just seems like its too much of a difference to attribute to tires, air temp. But i cant complain either!

ArcticWolf · 02-13-2008, 10:10 PM

15.9 gal tank, close enough. I fill around about the bottom of the gauge, barely before the light goes on (3 gal left)

RaceFaceXC · 02-13-2008, 10:25 PM

what mpg's you getting? im between 25-28 all city driving... ill get 23-25 on highway (80 mph)

ArcticWolf · 02-13-2008, 10:27 PM

rough number crunch = 20 all city, I don't see highway too often, town's not that big and I don't go anywhere (yet).

Last OT post by me on this thread - we can do PM's if you want.

GADGTGUY · 02-13-2008, 10:35 PM

Hey Guys,

I was just warned that my post violates some sort of vendor rules.

Sorry if I offended anyone.

I guess if you want to disucss things we can take it off-line.

D.

i run my tires 23 front and 20 rear in snow and have this huge thule rack with a fairing on the roof.

Nyah, aren't you supposed to run your tires a little higher in the snow?

I get about 22 MPG, I go about 320 miles for a tank of gas. I don't accelerate hard all the time, but I do occasionally. I suspect that if I drive less on highways, my MPG would increase. Cruising at 3k for 30 minutes is blah.

I run my tires 37F 35R, Kumho Ecsta ASX, which is now out of production.

My mileage does get a bit higher every once in a while. But I think it's going to stay there for a while, until I get an intake or something.

I'm suspecting you meant 33/30.

I have the same car and i get about 280-300mpt (miles per tank) city or 360-380mpt highway then gas light and i drive slow and quick with some WOT runs here and there.

Do you not have any street lights in your town? I see about 50-60 on my 15 minute commute in the burbs. Does your "driving hard" consist of WOT for more then a second or two?

Counterfit · 02-14-2008, 11:58 AM

300mpg?!

My drive to work is pretty short. 15 mins and i stop twice at stop signs and go over 3 speed bumps before im out of the neighborhood. then i do 55 for about a mile and a half. stoplight. then i do 65 for another 2 miles. stoplight. then i do 45-50 for a mile with atleast on stop for a light. up to 3 stops if i get all reds. then 70 for 3 miles. stoplight. Its rural highway/small town driving but not freeway driving. Yeah, when i get on it ill go WOT til im afraid to exceed the speedlimit anymore. My fav place to do it is one wide low traffic road where the limit is 65 and i usually go WOT til atleast 80. anyway, im real happy with my milage, better than i had thought it would be when i saw the EPA sticker on the window b4 i bought.

williaty · 02-14-2008, 10:04 PM

OK, TBS on it's way to me for testing. I'll let you guys know when it gets here. Who knows how long Customs will run it on their car before letting me have it

SilverSubie2.5 · 02-14-2008, 11:05 PM

HA! Good to hear, can't wait!

williaty · 02-14-2008, 11:16 PM

OK, since the community is interested in this, what do you guys want to see?

I have a plan for what I want to test and how to do it, but what data or test would you all be interested in?

HP, torque, AFR.

Unless you want to donate dyno time, HP and torque are going to be from a software based road-dyno. AFR is covered, I just installed a LC-1.

SilverSubie2.5 · 02-14-2008, 11:32 PM

Well, what results CAN you offer? Whatever you have, I'm sure we're willing to hear it.

williaty · 02-14-2008, 11:40 PM

The way I'm planning on attacking it is via logging with Enginuity. I'll be able to report back in any changes in engine breathing or AFR. Also, from looking at the change in RPM over time, software can calculate HP an torque, but the evaluation of breathing will have more resolution. Realistically, a TBS can only influence the amount of air entering the engine, so the airflow will tell the tale for power. I'll also be using the RPM data to calculate intervals (i.e., does it go from 50-70 or 20-50 faster or slower than it used to, etc.).
