Patriot sucks

MustangMatt96GT · July 2nd, 2008, 12:58 AM

you should have seen a drop in boost but making about the same power or so... did you seen any drop in boost?

jivepepper · July 2nd, 2008, 02:47 AM

About the same but we spun it 200 rpms higher. I have a 2.8" pulley and no serious belt slip, but I only see 13.3psi.

Plus the car was still making power at 6400 when he let out. It wasn't wasn't climbing real fast but it wasn't dropping off either.

should have gone with fox lake, heard many horror stories about patriot

00gtCoolGuy · July 2nd, 2008, 03:41 PM

i'm interested to see how this turns out...go with some mmr heads!!

This is an interesting thread to say the least. The fact that you didn't pick up any HP by switching to a ported head (regardless of the manufacturer) is extremely puzzling. However, if you are looking at STD numbers on the dyno, the 23 degrees of temperature difference would have a huge impact on measured HP. However, I would still expect ot see a measurable gain in HP even with those conditions. Have you contacted Gunnar at Patriot and explained the experience you are having?

I have not cailled gunner yet. There was a 26* temp diff and he always uses standard at this shop. I dynoed on March 3rd last time.

I'm trying to grind down my cobra calipers to get my skinnys to fit. I want to go to the track tonight. The best I have done at this track was a 11.39 @ 127.55 in good air.

I did a compression test and everything is fine.

left--right
125-125
125-125
125-124
124-126

I got CEL on the way home it was for a fuel rail sensor malfunction. So I put on a extra I had I will take it out in a bit and test it out.

How did your new power band look? Was it flatter than the previous band? How does the car feel?

Screw the dyno, how is the car responding and what did the heads do to your ET/MPH

Thats what im thinking. Did you notice a feel of extra hp?? Myabe once you get to the track you can get what you put your money in. Sorry man i hate it when stuff like that happens to anyone.

About the same. It feels good at wot.

Can't go to track I need longer studs to get the skinnys to work..

MATT02GT · July 2nd, 2008, 07:42 PM

The deep dishes shouldnt wiegh that much more.. I compared mine and the
18x10's w/295's were 5lbs more than my 17x8's. But yea sorry to hear about the heads, whats cams are you running in them?

Yeah i bought the heads a l while ago. But I will never buy a Patriot Head ever again or anything that is even barely related to Patriot Performance Piece of Shit Products...

Anyway let me know if you need anyhelp getting those studs in... ive done that a few times. The fronts are so much easier than the rears.

Mine are 17x10.5's with 315's. Each of my rims were 11lbs heavier and each tire was like 9-10. I forget exactly now.

So about 38-42 lbs. You must have some really light 18's. I had the cast aluminum satin silver rims not the bullets. The rims weigh less than 20lbs each

Post up your previous and new dyno sheets ... I would be interested in seeing the difference between the 2 curves, and of course the 26* could def. have played into this although this shouldn't have completely destroyed the gains.... Also, I'll be interested in seeing the new numbers at the track because a dyno can only show so much

JohnnyZ · July 3rd, 2008, 01:15 AM

That's weird. I picked up a piss load of power on the Stage II heads.

Then again, I needed the volume. What most people think that is that flow numbers make horsepower.... not true, unless u need the volume like I said. However, air velocity is where you pick up your horsepower from...

jivepepper · July 3rd, 2008, 02:48 AM

I'm thinking about going to an 8 rib set up 2.75" sc pulley and an overdrive crank pulley.

You think at 515 I could of used some more volume.
