Better hurry up OP. My car, same mods for the most part, will be tuned on Tuesday
What restrictions?
I will address this later....
Guys.... I bought my 2008 new in 2007 and have played around with different superchargers. Bought.... tuned..... (not happy).... sold..... Repeated this cycle more times than I care to think about.... maybe $10k to $15k worth... spent and wasted..... Try not to be tempted with the "next" generation supercharger hits the market. My advise is to spend the extra $$$ now and get the biggest, baddest blower out there. You'll never have to "upgrade" again. I did exactly this. As a tuner, I can say that the greater the supercharger volume, the more air it ingests... more hp to be made. I literally see it in the MAF transfer function as well as datalogs for all my different combos. And think about this >>
The typical blower redline is 18,000 rpms. The closer you get to this, the more efficiency you lose....
With my 2.3 TVS, pullied with a 2.50" and a 15 percent crank pulley at 6,000 engine rpms, the blower is spinning 19,500 rpms, exceeding redline. No more room for improvement. Highest boost datalogged was 19.4 lbs, highest load value recorded was 1.94 (great indicator of power made).
With my current 4.2 with the LARGEST blower pulley, 4.00" and the same 15 percent crank pulley at the same 6,000 rpms, the blower is spinning a mere 12,188 rpms. Plenty of room for improvement. Highest boost (to date) is 20.4 lbs, highest load was 2.32 (compare with prior setup) AND MOST IMPORTANTLY, I achieved these numbers revving to 4,500 engine rpms and ONLY 43 degrees of throttle angle. Am I impressed? What to do think? So quit dinking around with a "small block" blower and go big and be done with it...! I'll never go back!
Who needs e85? Do you guys know all the drawbacks to running 85 percent alcohol in an engine not designed for it? They far outweigh the advantages that can be gotten another way without any of the drawbacks... Personally, I will not use this junk and subject my motor to a premature death. I'm working on something very big and looks very promising. More to come in the weeks and months ahead...
I lived in Texas most of my life, east, central and west Texas... East Tx has only 93, West Tx has only 91. Further east is all 93 and west is all 91. The split happens somewhere around Abilene. Don't know why. Probably something to do with east and west coast distribution centers and different origins.... just a guess.
Depends on your intent.
Drag race? Calculate what ratio you need to cross the line at redline in 4th gear. You will need to know top speed to do this. So calculate based on your projected top speed.
Just dinking around on the streets? Lower gears will "feel" more acceleration. In all reality, it feels this way because you have to shift quicker. Bottom line: In a drag race with 3.31's and 3.73's, there is no improvement in E/T with either. So what does that say? It's all about purpose and feel...
Pump gas restrictions as in if I do full bolt ons, Gen 2r, 2.4 pulley , and 10% Lower, that’s safe on 93 pump and stock engine? Years from now once I build the engine and do cams and bigger blower. I have always thought the safe limit for 93 octane was around 700-750 at least for our cars.
Nice mods. I have a 2007 GT500 build that I just finished the installation of a stock 2013 Trinity blower.
I added the dual fan heat exchanger, 10%, JLT 123, 65 TB, Off-Road exhaust, 373 gears and other mods over the past few years. Hopefully they compliment the new SC well.
I have to add a wideband and BAP yet before I can get a new tune sent.
I currently have a SCTx4 handheld but I’m considering going with the nGuage for ease of data logging.
What type of guages are you using for your setup?
I apologize if I jacked your thread. It looked like we’re on similar builds so figured I’d chime in.
You are going to love those mods. I drove my 2011 stock for 2 years before modifying it similar to yours. The best part is it is like getting a new car again. I would recommend a bigger heat exchanger next. Nice car Enjoy It!
