It sucks being new the world of f/i. So much to learn, so little time.

 

i think the motor should do fine.
Turbocharged motors do 15 PSI on stock motor.
the supercharger is less stressfull.
i think the 800CC are overkill.
but we'll see results as soon you get it tuned.

 

Definetely watching!

 

i've run 20 psi on 650cc injectors before. they never maxed out, and are still running strong today. you dont need 880cc.

 

I thought before you were going to run 1000cc injectors and run it on a base map. I guess you decided against that and have it tuned lol.

 

Why a water-to-air IC? The TRD S/C doesn't even have an IC so I'd be interested on how you'll hook this up. Water-to air is typically only used in racing applications since it's hard to keep a supply of cold water. With a recirculating design, the water heats up after going through the IC, even with the seperate radiator, so with each pass the water gets warmer and warmer until it is less efficient than FMIC air to air designs (water holds heat better than air). On a drag strip, the water only needs to stay cold for 10-15 seconds, then gets changed out with new icewater for the next run. If you're going to drive this thing off the track, condsider the following alternatives:

water / methanol injection - sprays a water / meth mixture after the supercharger. This has the double effect of chemically cooling the air as it evaporates and acts as an octane booster to stave off detonation. AEM, Perrin, and Snow performance. 1 gallon should last a tank of gas and windshield washer fluid can be used if it's 49% methanol.

FMIC chiller bar - passes compressed gas through metal coils in front of the FMIC, can be CO2, Nitrogen or Nitrous. Not recommended for long term driving as it depletes the bottle quickly.

Cry02 chill bulb - drops a bulb circulating compressed CO2 into the air stream to decrease charge temps. Again, needs the bottle refilled to stay working.

 

^^^the one that Dan Gardner is running on his tC does have an IC.

 

^^^^^Ooooopppssss, I meant to write that, I didn't know my co-worker Evelyn was logged in on this computer lol......

 

Well Dan Gardner is running 700cc injectors on our standalone with 11 PSI on the S/C. They maxxed out the 550ccs we provided on the 1st set of tuning dyno runs.

The local fella I tuned on his S/C at 10.5 PSI, we maxed out his 550ccs at 5500 rpms. I could not even get enough fuel to get the car to run right when it built the 10th lb of boost. We where running some serious duty cycle there too. So we switched him to 700ccs.

 

So Paul the Supercharger needs more Fuel then a Turbo set up ?on higher boost ? i would like to know cause i plan on doing a 14 PSI pulley too .... combined with more discplacement.

 

The intercooler effect involved in the turbo systems keep charge temps down and allows for leaner AFRs, which in combonation help stop detonation, while the S/C guys lack it and just have super high charge temps (especially with more boost). As a result, with no form of helping to stop detonation on the S/C all you can do to help combat it is to run richer AFRs with colder plugs and some higher octane fuels.

 

Got it ... didn't think about that part.
thanks for explaining it... all makes sence now.

 

i have the 550cc on my 12 psi pulley and i am not maxing them out. but then again i cant pass 10.5psi lol

 

Watching

 

Still having problems with the Belt ?

Thread starter :
How much did it take to get the 14 PSI pulley made

 

not to burst your bubble - but i doubt you will be hitting 350whp - i will be suprised if you hit 325whp

 

i'm running 700cc from deatchwerks and it's barely on 20% duty cycle for 13.5 psi...thats on a very safe tune too since i'm currently not running any meth or means of cooling the charge.

 

I am running my stock s/c injectors and have a 10.5lb pulley - and im at the limit of being safe.

 

i dunno it might be the belt cause i only hit like 10.5 and thats it. whatever i am going turbo anyways
