So I finally got the car to the dyno, tuned and now a dry day to test this out.

Mods: Injen SRI, RRM headerback exhaust(no cat), UD pulley, RRM piggy,RRM motormounts, Zaklee damper, RRMswaybar and perches, RDD tiebar, RRM slotted rotors w/ axxis brakes, Toyo Proxes 4.

just added the mounts exhaust, all suspension, and tires. What a difference.

Alot of gain throughout the band which surprised me. i have an auto and the torque gives me a little tug to the left off the line and hitting second. thing flies off the line without any real squealing. No wheel hop. and just keeps moving until, well, really high speeds.

Highway went great from all speeds and RPMs it took off like it was off the line all over again. downshifts beautifully with new mounts.

Did a little cornering and i can't believe how much improvement their was. I thought our cars handled great but now i wish i didnt wait so long!! tires held great and you could feel how much stiffer it was and just overall felt like their was alot more control of the car.


CONS- not many. motor mounts at first gave me seat massages, but they i guess broke in and now are good at idle. Already got pulled over b/c the exhaust is soo damn loud without the cat, and annoyingly raspy. but the highflow is in my trunk and goes in next week


NEXT WEEK cam gears and cat. hopefully hood and spoiler. once the P&P intake manifold comes in that too. then i think a TB and then back to the dyno for more tuning!!

 

what are the numbers? u did say u went to the dyno

 

152.72HP 151.66TQ which for an auto isnt really too bad at all.

 

awsome review

im saving up for a full suspension overhaul

 

yeah i toyed with the idea of springs b/c i had the money for them, but instead i will wait and next time i do a big upgrade ill get the coilovers. now that i've driven this setup im not in a rush to do that since this is just so awesome.

 

Did you get your piggyback tuned?

 

Isn't that what normally happens on a dyno?

 

not bad at all

 

My piggy didnt need tuning really. the AFR stayed within 12.8-13.1 and they did a tiny bit of tweaking but not much really.

Sidenote: CEL came on last night. sure it is from the header/DP so once i get the cat in ill reset the ECU and see if that fixes it.

 

I'd get the code checked just to make sure I was on the right track. Many auto parts stores will check codes for free.

 

don't mean to be a downer but with your mods i would of expected more of a gain unless you meant whp. doesn't a stock autoRA dyno 130-135whp?

 

FYI -- all dynos measure whp......unless it is an engine dyno where it hooks directly to the crank or flywheel.

 

I believe someone else mentioned that every mod gains a little less HP being an auto.

If you think about it the SRI doesnt gain much (3-5), the piggy smooths out the curve but doesnt give you much more peak power either. The headerback exhaust and pulley are really responsible for the majority of these gains.

And not to mention a little over 20whp over stock may not sound like much but it doesnt even feel anything like the car i bought anymore. on an 8cyl you wouldnt feel these gains in fractions of how it feels in a 4cyl.

and this is still all prep for bigger mods like IM, TB, Camshaft, etc. and once the loan is payed off turbo.

 

I dont know about you people, but every mod I did to the car, one by one, made a sizeable impact in the car. Remember that there are many factors affecting a dyno pull. Temp, pressure and the like

My BPU mods yielded me a little over 30 hp, wich is pretty nice by any standard, not even 1k I wasted on mods, and im drivng a 14 second car, bnot too shabby

 

Anything a manual dynos will be 10% lower in an auto car. Drivetrain loss on average in a manual car is around 20% with an auto being around 30%. These are good rules of thumb.

A little off topic although I notice you have the RRM mounts and the Zaklee dampener...do you feel a difference with both? You really don't need both...unless I am missing something here.
