Sorry to ask more, seems we should have a sticky on all sc questions. I am now concentrating on the kd mammoth kit for my 06 gt. I will have the cash to up grade the bottom end, but would like a super charger now. The kb claims 775hp on a stock engine, what is with that??
Well... KB exaggerates a little. Yes, you could make 775hp on the stock bottom end. That engine probably only lasted that one dyno... That engine was probably destroyed by the end of the test. That's WAY too much for the stock internals.
Why does edelbrock proudly proclaim made in America? How far can that kit go?
Who know... Another one of those "keep the money in America" deals I think.
That kit looks pretty solid... I'm sure you can make 700+ in the long run.
How far can I go with a ford racing
whipple kit?
5 words: Do not go Ford Racing. It's not a bad kit... But WAY to expensive. You could go twin turbos for the price they charge for their 500hp kit!
Do any of you guys auto cross with twin screw super charger?
That's a good idea! Low end torque would help you out for sure from braking and accelerating all the time.
I feel like the old days waiting to buy a stereo, when the cd player was on the horizon...everyone was afraid to buy because something better was coming our.
Many thanks,
Doc
LOL! I know what you mean! I'd highly recommend you look at all your options before pulling the trigger on such a HUGE investment.
First off, twin-screws (IMO) are the most FUN way to go when going with a SUPERCHARGER. Gobs and gobs of low end power make spinning the tires at 50mph a blast!
But... Turbochargers are another not-so-mainstream way to go. First off... Most turbochargers have the capability to exceed the Mammoth!
They also make a load more power on lower PSI. But... They start making boost once the exhaust is flowing. You'll hit full boost from 3-3500rpms... A little trade off between that and the twin screw.
At 8 psi, you'll make 450+ rwhp...
You'll get better mpg, because you're reusing exhaust (more efficient system)...
You'll be able to turn up the boost at the spin of a dial...
05-09 Mustang Single Turbo
Those are possibly the best results and prices I've seen with a turbo. For the record, the smaller the turbo size, the sooner the boost!
Here's some excellent information about turbochargers below... A conversation I had with the people from the website above.
Question 1: Why shouldn't I buy the 76mm kit? It has a higher possible output, but this car will be a daily driver. It will be on a stock engine, at least for a while, so boost levels must remain low (8 psi or less).
Answer 1: It is true that the 76mm offers more total power potential - up to about 800-850 hp. The only reason not to purchase the 76mm system is that you are not going to be able to use the full power potential of that turbo on your stock engine. However, if you are going to build an engine, it might make sense to go for the 76mm, as it will be cheaper than buying a new turbo later in order to upgrade. The downside is that the 76mm turbo will not spool up as quickly as the 60mm turbo (4,000 rpm vs 3,000 rpm), unless you do the 76mm Ball Bearing option.
Question 2, 3, 4: What kind of numbers does the 60mm stage I kit put out? What's the lowest boost you have tested & its output (i.e. 6 psi - 450 HP)? What is the highest boost you have tested & its output?
Answers 2, 3, 4: The 60mm turbo is capable of about 600 rwhp, but you can't do that on your stock engine. You should reach 450 rwhp, which is about the limit we suggest, at about 6-7 psi.
Question 5: What about the 76mm kit?
Answer 5: See answer 1 above.
Question 6: I have an automatic. I don't expect there would be any issue with that?
Answer 6: Shouldn't be. The system actually works better with an automatic. You should, however, change your torque converter (I can sell you one for $599).
Question 7, 8: When does all this power kick in? What RPMs?
Answer 7, 8: You should be at full boost (on a stock engine) at about 3,000 rpm.
