Holy Crap it's fast!

Well I made my own boost controller yesterday and went to try it out today. Apparently the spring I used was a little stiffer than I thought it was. I put it in second and stomped on it from about 35mph, the turbo spooled to about 1.25-1.5 BAR(about 18-21psi) and the tires broke loose. That is, ofcourse, WAAAYYY too much boost for an SR T25. I'll have to go back to the hardware store and find a softer one. I think I went from 35-75 in about 2 seconds though. My fiance was with me and she just said, "HOLY ****!". Then we both had the biggest **** eating grins on our faces. I think she just likes me for my car sometimes...

Oh it feels good don't it ! Now just think what that much boost will feel like like on a much efficient blower.

I'm scared to even think about this kinda boost on a T28, or even a T3/T4. I'd need WWWAAAYYYY bigger tires!

how much boosy can ur current setup handle safely? arent ur running 9.5:1 compression?

[c-rad]

∞ PSI!!!!1!!!1!!

[float_6969]

LMAO @ c-rad. Where the hell is the infinity button on the keyboard? JK!!!

Zero-grip;Well it didn't bat an eye at the boost it got from T25. I only did it twice, and from watching the controller the 2nd time, it was knocking a little, but nothing that I could hear. It was 91 octane in the tank as well, and yes, I'm running 9.5:1 compression.

[Coldspawn]

haha, 260-280 whp beast!

[zero_gripS13]

which device tells u that it knocked?

get some better gas and itll prolly take some mad psi from a t28 once u get one

I have a knock sensor and the SDS will tell you in the second gauge screen when it's knocking by changing the degree symbol to a "K".

I'm taking it to the dyno on monday and I went and bought 5 gallons of Toluene today.

(05 Gallons of toluene @ 114 Octane) +(10 Gallons of pump gas @ 92 Octane)-------------------------------------------------- 15 Gallons of "Rocket Fuel" @ 99.3 Octane

I figure that even if I decide to get stupid and turn the boost up with this turbo again for a couple of dyno pulls, that will prevent even it from detonating at that kind of boost.

I'm such a dyno queen....

[biosehnsucht]

what, no 93 octane? damn sucks to be you.

[zero_gripS13]

sweet cant wait till u go float.. i wanna see what u car does.,..

[8ggalant]

i know u'll love a 28 float...mine felt faster at the stock 6psi than my ca turbine at 10/11 psi

[float_6969]

I have never liked knock sensors. I have never found them to be accurate. Too much noise from the motor makes them go crazy.

All I am saying is, do not rely on it totally.

I couldn't agree with you more, BUT it is a nice "safety net" if you will. From driving it for the last few weeks, I've got it so that it won't pull back timing in a daily driving situation for sure. I've only actually HEARD it knock twice since the rebuild. Once on my first day of tuning, and then once again with my stupid MBC. I can adjust the sensitivity of the Knock sensor with the SDS and also tell it to ignore any noise over a certain RPM. I think it might have saved me some trouble this last time when it overboosted with the MBC, so I'm thankful for it.

[tyrannix]

did you actually use the toluene?how did it work out for you?

[float_6969]

Yea, I've used Toluene a bunch of times. I'm hoping to go out to the drags this week, and maybe the dyno as well, and I intend on running the toluene again. It works great. I have NEVER, not even once, heard my motor knock when I was running a toluene mix. It's good stuff. Just don't fill the tank with it because it doesn't like to vaporize until it gets pretty hot. BUT it has a higher energy output per weight/volume (I don't remember which) than gasoline, so you could actually make slightly more power, simply by running the toluene.

[tyrannix]

thats awesome,

ill just make the tolouene witches brew instead of running an ethanol mix now

how much/where did you find yours? ive only found it really expensive. sciencelab.com is $34 for a liter

[Shift_Tommy]

i think homedepot sells it

[float_6969]

I just bought a gallon yesterday from Sherwin Williams, I didn't get the hookup I normally do, so I paid $13 for it.

[CA19DET]

i can tell you boost is a hell fo a thing, i was tuning a little this weekend and was running 20psi (on a T3/T4 50T .63) and my 245's were breaking loose in 3rd @ 5000rpm from a roll hehehe.. dont tune on the street. trying to counter steer and keep the laptop in the car as you whip from side to side is tough..

[float_6969]

See, SDS, and it's little controller have it's advantages! I've done that a time or two with the controller in one hand, and counter steering with the other! LOL!!!
