Hi Guys, great forum, really impressed with some of the builds and the knowledge base here.
I'm from Australia and recently bought a 2014 WK2 SRT with a Ripp supercharger kit installed. It runs a dual 3inch stainless system with extractors, front mount and I assume the standard supercharger which is sold with the Ripp kit. I've measure the pulley at about 88mm (very outside diameter) which is 3.45 inches in US talk.
Dyno report I got with the car states 535hp at the wheels, im guessing this is on 6PSI boost?
Car, motor and drive train are in perfect condition having done 20,000 miles.
I've done a best of 3.5 seconds 0-100kph, which is equivalent to 63 mph, regularly is more like 3.8 though.
1/8 mike runs are around 7.5 seconds depending on launch.
I'm from the coldest part of Aus, typical summer good day is around 75 (25 celcius) with much of the year 50 to 60 normal.
I live at sea level too.
Please offer you're advice on the following, happy to be lead on the right track if I'm off.
My goal would be to have 750 wheel horsepower, which should be very comfortable 10 sec 1/4 miles.
The first thing I've learned from reading is these bottom ends are too fragile, so strengthening is recommended.
With workshop costs in Aus being so high, it's actually going to be cheaper for me to import a short block (strengthened and decompressed) than it is to rebuild my current motor, and put that in.
The logic there is that if anything goes wrong, or I want to take the car back to stock, I've got the original, unmolested block ready to go again too.
Is there any reason not to go 440ci here? They don't seem to cost much more, and I figure it just makes the hp easier to achieve.
Most companies selling short blocks offer different compression ratios, is 9.5 - 1 a good compromise or will that make it lazy off boost?
Next, is it possible to retain the Vortech Ripp supercharger and have it modified with my goals in mind? If so, what internal changes are done?
Funding all this isn't really an issue, however it will be satisfying if I can retain some existing bits.
Finally, struggling to get info on the transmissions, seems to be varied opinions on how much power they can take. What mods (if any) can be done to them?
Advice from those who have done this before is much appreciated.
