V6 vs. 99+ 5 speed GT with a magnaflow exhaust, including:
X-Pipe and cats, a K&N FIPK, UDP, and Superchip.
The answer is right on there, but I bet most never thought a V6 could make
that kind of power!!! Here's proof! I consulted on the setup and RPM did the
porting, the cam is one of my old grinds and too small, but Justin
(our fearless V6 owner) is making a few changes and may use
a new cam of my specs and a few other changes to optimize
the setup as it currently is.
Those of you that guessed RED before seeing the answer win a COOKIE!
Sweet deal, huh??? I did not do alot for Justin, but troubleshoot,
and suggest changes that made a huge difference, but at least
it is now making killer HP and Torque and uses one of my old cams.

my car had 7,000 miles on it, and I got it for $12,000... and it has EVERY upgrade except leather, actually, had it special ordered so the only thing left off was power passenger seat and leather seats.... soooo , then I stole it from her. (Bank took it away, sold it to the Ford dealer for near $15,000 I guess)... they had it marked at $15,500... but rethought when no one wanted to buy it until me... like a year and a half after they got it

4.2 (stock bore, so it was not a 4.3)
LT's and good duals (2.5" I believe)
small cam (I'd go bigger next time and Justin is looking into it, I will spec it)
BV heads (but I would use stock valves with stock 3.81" bore block)
wildly ported intakes and 70mm TB
plus a killer tune by Jerry of FordChip
Justin needs a bigger MAF and the cam will be changed later,
he may also try 1.8 RR's just to see if that helps any. It should,
but not nearly as much as a bigger cam. 1.8's only add about 4%
to the valve action and around .020" of lift is part of it. I will add
considerably more to the next cam, lift and duration both. But not
too much extra duration, as this combo is easily beating a competitive
4.3 that has nearly 20* more intake duration! Gotta match the intake
style when you cam it up, too much duration kills torque and when the
torque is right, it carries thru with killer HP. This is the SPI's best trait!
RGR, do you suggest larger exhaust valves on a 3.8 splitport that will be run mostly N/A, with nitrous @ the track? The setup will be a stock bottom end, +cam, + ported heads. I guess the question is, Will the cam, and N2o alow larger valves to be usefull without loosing bottom end?

I'd email me if I were you, and we need to discuss if this cam is meant
for maximum all around HP or on the bottle HP. Most people need NA HP
and occasional juice usage, and for those peeps I would retain stock
valves... Instead of going thru all the variable here, let me ask you the
Q's and then I can make suggestions. Email me!
Hey RGR, can you explain to me why my numbers are so bad?? I know im not 4.2, but I was thinking my 3.8 would make at leaste 200+ rwhp with what I have... I mean come on, I went from 140rwhp with boltons only to a whopping 160rwhp!!! Thats a whole 20rwhp... when I was expecting at least 50. :disgust: :disgust: :disgust:

1. Lack of proper tune, SCT could mean anyone! Was it mail order?
2. Clogged Cats... lack of torque increase indicates this too.
3. Engine needs rebuilt... :uhh: that would be bad news.
My best guess is that it's #2, maybe combined with #1.
But any tuner can only tune for a healthy car, clogged
cats or toasty engine can't be tuned for at all.
If needed we could get you a reburn with my guy, after
the other issues are cleared up. If there are any, but I suspect cats.
For your mods the cam is kinda small, do you have higher CR?
It's also an SC grind, and my very first cam spec I did. SC later?

Robert the thing is look at his Dyno numbers stoick with bolt ons. I have never seen a 94-98 Dyno that high with just bolt ons. I am betting he got a 40+ hp increase and the first stock dyno numbers were bad. But that is just my opinion
With my project everything is going to be new. Not taking any chances. New fuel pump(gas tank completely cleaned out) and all the other little things will be changed(new battery for instance) so I can cut out any wondering what could be wrong....

Well, most stock 5 speeds are @ 115 RWHP or a bit more.
So he should be maybe 130 RWHP after boltons, You are right,
140 is a alot for boltons. Was the 140 with tune? A stock tune
does not work that well with major airflow mods like these...
José was making right at 190 RWHP with that basic stuff,
with a 5 speed and same cam, but stock valve heads.
It was not optimized for an NA combo, but was tuned on a dyno.
I still think it's the cats and tune. Probably a pre-HCI tune on there.
140 RWHP with boltons and chip is not bad, for a pre-99 car.

Then you need to rebuild it BIG BORE.
Ford's pistons are 20 and 40 over, maybe
Rob can get you some bigger forged ones later.
I have a set of forged rods here, SC, for sale!
You'll need BV heads and all that stuff.
To do it right at least.

Corey said he will have me a list of everything I will need.
boring it .030 over right now. I don't want to take chances of something happening.
