See my video on a go kart race engine build For valve overlap and scavenging effects with a long tube header better explained
@lovethesmellofracefuelinth73744 жыл бұрын
I've been thinking about replacing the ones on my Challenger SRT8, even though they do have pretty decent headers on them from the factory. But we always want more, and have been checking into some recently for it. Kooks look really good as well as American racing, and are the two best from what I'm gathering. It's already got really good pipes on it, and is made up of 3" stainless with open chamber racing bullets and flow so much better than the stock ones did

1980 my best friend and I got our drivers license the 1st thing he did was put a 650 Holly carb on his 350 CHEVELL it ran like crap , I told him the carb was too big , he sead Bullshit ! So I took the 2barel carb off my Vega. And baceplate adaptor and we burnd rubber all day long. Until he got city ordnance Ticket😃😭

you dont need back pressure right? you just need the right timing for scavenging

Also as far as stock manifolds go, I've heard that the Cobra pipes actually flow fairly well. I still have my stockers with a Mac Prochamber , hiflo cats and Borla Stinger catback...and I love the sound my Terminator makes! Enjoyed the video Dan.

Thanks! Yes, I’ve heard the manifolds will handle 700hp, but that it doesn’t hurt to have better flow where possible

Thanks for your informative video. I have a question, what's would be the difference in sizes when buying long tubes? By sizes I mean 1 3/4, 1 7/8 and so on, and also on collector size like 2.5" or 3". Thank you
@dannyjohnsonsgarage6 жыл бұрын
You’d have to see what each manufacture does, but these are 1-3/4 inch with a 3” collector, which goes down to 2.5” for the x pipe
@randy427504 жыл бұрын
Ok. So if I put long tubes will I be able to put the catallactic converter?
@dannyjohnsonsgarage4 жыл бұрын
The long tubes will come down and then you'll need to add cats after that in the H or X pipe area if you want them

I have a 04 cobra with 2.8H kenne bell tuned on e85. it is making around 700whp at about 19psi. I am thinking about either increasing boost, or doing a small shot of nitrous. 50 or 75 shot. The engine is stock besides arp 2000 rod bolts, arp cam bolts, arp head studs, and gt500 timing chain tensioners as far as strengthening. Would you increase boost, and add more stress on the crankshaft, or run a small shot of nitrous and also have the cooling benefits of nitrous over adding more boost and straining the crank more. I'm afraid to break the snout, and I feel that a small shot of nitrous would be much safer and add power and cooling properties of it to the engine. What are your thoughts on this? Thanks for your videos, I have watched a lot of them!
@dannyjohnsonsgarage6 жыл бұрын
A small shot shouldn’t hurt too much- however, nitrous will lower intake temps, but also burns hotter, so it may not be the heat reduction you’re looking for. I think you’re at the max safety level that I would personally suggest. It could hold another 100 hp, but you have to be very careful of a lean condition or bad fuel with that power level. You’re +100hp over my car. Way cool!
@infine0n6 жыл бұрын
Danny Johnson thanks for the response. I probably should just leave it how it is, but was just considering a little more power. I should probably be thinking about cooling mods more than increasing more power lol

With mid length headers can I still use the factory pipes?

No, you’ll need shorty headers for a regular mid pipe. Of course a cat back can be used with all versions of the long tube, mid length, or shorty

So stock manifolds work best with a supercharger?
@dannyjohnsonsgarage2 жыл бұрын
No, headers are always an advantage for scavenging and clearing out old gasses so they don’t go back into another cylinder. All I was saying is for flow rate, stock manifolds will work sufficiently until 700hp. Consider emissions and ease and cost of installation, but by all means put headers on if you would like to upgrade. You may not see it on your dyno sheet, but the gains and benefits are in other places

christianthebombcs You won’t gain much from shortys to long tubes. For the money look into the eaton m112 cobra supercharger swap. You’ll be able to make more power than the engine will ever handle. I owned my V6 for 12 years. I’m not being rude, but the engines just won’t make much power with bolt ons. Step straight to a supercharger for the money.

Hey Danny I have an 03 cobra with a ported blower and bassani mid length with a 2.8 pulley only and I see 11 psi does that seem right? I’ve seen people have more psi with a 2.8 pulley but I read on svt performance that headers and ported blower affect boost
@dannyjohnsonsgarage6 жыл бұрын
Savage Habits Yeah, it’s normal to loose some boost pressure from headers. That’s probably about right, but maybe 1-2 psi low. Has the car been dyno’d? I’d be interested to know output.
@modlist61296 жыл бұрын
Danny Johnson yes it has, the previous owner said it made 490 at the wheels, so far all it has power wise is bbk intake, 2.8 pulley, bassani mid length headers with x pipe and bassani catback! Ported blower and dyno tune Also has 3.73 so that probably changed the dyno number a bit, but I plan on going with a dragon plenum and throttle body and a 4# lower.

Danny Johnson Hey bud, just wanna ask this quick question 🤔: Since I have a 2006 Mustang GT & it’s an automatic with the Borla ATAK Exhaust & a few other mods as well but since I just got a Shorty X-Pipe Brand called “Dynatech SuperMAXX Catted 3 inch to a 2.5 inch X-Pipe” & just about to get the LT of the Dynatech SuperMAXX Stainless Steel Headers off from JEGS.com & it’s $899 but the X-Pipe says it’s already a catted -Pipe as well, too. I wouldn’t need to put any kind of “CATS” to be put on since I already have the Borla ATAK Exhaust that I explained earlier but I wouldn’t need any kind or put any “CATS” on it would I 🤔??
