Alpine or Impulse for a nytro?

[Hornet]

I come back to my original thought, what are all these header builders using for material and what is the application? I don't know but I'm willing to bet its either 304 or ideally 321 16G. The cast headers aka Ulmer or whatever they are now have a pretty good rep or so it seems mostly because a cast unit has the meat, so again JMO it stands to reason that if you use a beefier material like Impulse then one would think that it should last better. Again IMO you can't compare a 16g header (which when you put the caliper on it is pretty thin piece <0.65") to a cast unit because the cast unit will be inherently inefficient but last forever because of its mass like a turbo diesel truck manifold which we are all driving. Why aren't they always cracking? Cause they are over engineered not to by being large enough to take the heat. If you go to the Burns stainless site they have some pretty good info on building turbo headers etc but they don't ever say this is for your daily driver. They sell 321 SS 16G stuff mostly for race apps. The Impulse setup gives you a pretty decent compromise with good flow and durability/beef also in 321 which is the only real option aside from Inconel. There's good weight and bad weight on a sled especially a Yami. Reverse is good weight and so is a beefy header. JMO. I know what I would do.

The Impulse website states that the shorty header is constructed of 321 stainless that is 3/16" THICK. MUCH thicker than 16 gauge.

Ive broke 3 impulse headers, all have been replaced or repaired by paul. A header is a header, it will break sooner or later. However paul has been great about getting them fixed and back to me or replace altogether.

You are right.....just a matter of time. How long did it take for them to fail?

Paul sells his kits complete now because they come with full standalone fueling systems, no pushing buttons EVER....

I still havnt upgraded to the standalone i still have the prologger but i love the kit. One of my good buddies on here MotleyOne built a couple sweet impulse sleds last year and is working on another right now that will blow people away. With the new standalone you can run up to 17 lbs with no motor work and just a head shim on pump fuel. We have run all the way to 22 lbs on 50/50 110 pump in revy. Also, Pauls new header is by far the best on the market, he has hours among hours on his new design and it gets the Tial BOV set in the perfect place. Not speaking as to the other kits, but all pauls stuff is top notch, i only speak of what i know certain and he uses the best parts out. Customer service is great too, he tests his products 100% before he sends them out and I think that you would be happy either way.

Remember if you would want to for some reason switch up to the boost it system there are a ton of guys out there who would buy the standalone from you...but i doubt that you will when you install the kit, i have riddden several now with the standalones and for a true never touch any button turn the key and go sled, it cant be beat.

just my 2 cents...either way you'll be happy

Would like to see a nytro run 22psi for RD.WOuld say 19 is max,the engine will break

 

[MCX KILLER]

both great kits both have excellent customer service pick the one that works for yah the best.iam going on 8years with a alpine turbo no complaints any issues i have ever had they took care of me.

I agree.i have bought kits from paul and dean,they are excellent.Dean and tod ship stuff ASAP to Norway if i need anything.

You may need a new engine builder. I ran mine at 26-28 lbs day in and day out. I say 26-28 because I was goin so ****in fast up the hills I could not look down for more than a split second.

28psi ha ha ha the engine had not lasted many pulls. ha ha il tell paul next time i speak to him buy a new boost gauge ha ha

 

[franklin]

Whats so funny? I've ran mine at 19-22psi for 2 years now on stock internals.

LOL, please do. Paul knows all about my sled. Apparently your into name droppin when you don't know **it from puddy. Give Paul a shout and ask him how much boost he was runnin on his hill drag sled that won the "Big Dog" a few years ago. Ask him if he had to rebuild or replace that motor. You think he won (Mike Irmen riding) that race on 19 lbs. Your out in left field buddy. You don't have a clue what is done to my sled yet you talk s**t. LMAO
I have multiple witnesses to my sled and the boost it will pull. In fact, I will make a witness out of you as well, better yet why don't you come ride it for yourself. I got no problem with skeptics throwin a leg over my sled. I live in NW Washington.

Dont you think it is to far for me to travel We are talking about nytro? If it is a apex i agree

It is a Nytro, Hurricane block (ductil sleeves and ringed), head work (machined ported to a tested 170 + CFI), Carrillo Rods, JE 9:5:1 pistons (Hurricane high boost edition),RD Springs(Hurricane edition), extra long head studs ran on 116 Race Fuel with Methanol injection from 12 lbs to full spray (3-100 ml nozzles) at 18 lbs. She is well protected from detonation; the only issue to run up to 28 lbs is the head lifting. The ringed block and the extra long studs prevent that from happening, if I remember correctly the head is torque down to 65 ft-lb’s, that’s almost 40% tighter than you can get with head bolts or at least what is recommended. She does run up to 28lbs and I have had it there on multiple occasions. That is real world testing, not a dyno, in the mountains. If she let's go so be it. I'm not about the status quo, to me it's not fun unless you are pushing the limits.

good mods there, but its no more a nytro engine,we were not speaking about steel sleeves and closed deck. and we were talking about impulse standalone. if you got a motec you dont need meth inj. and this leded hi okt fuel.a nytro engine with only arp studs will not last over 20psi for RD

They are good MODs and it is a Nytro and it is the Impulse Standalone that fuels it. I also do not need Meth injection to hit 28 lbs, I run it for the added protection AND the extra power I get when it comes on. Once I get the Impulse Timing Control put on her she will squeeze out some more power.

do not forget to change the stock egnition and coils,they are only good for around 21psi,they do not make enough spark to power your sled. http://www.youtube.com/watch?v=MAPaJzWxb5k

Well we have ran our Nytro/Iqr at 26lbs plus before many times, not to mention have jumped the sled over 150ft more than once and pounded many whoops without one header failure. We also run it in our quad and its holding up very well, not saying they wont break but they sure do hold up well for us.

We run the new Nytro stand alone with cam sensor,timing control etc and it works very well. I would run our sled against anything out there and Paul takes care of you very well.

Hurricane mods to the engine? Are you using stock coils??

 

[XtremeSpeedShop]

Carrillo rods/pistons, Xtreme motorworks cnc ported head, plus one valves, arp studs. We are using Impulses new stand alone that gets rid of all the factory yamaha stuff, factory Nytro coils on it now.

Are you runing water meth? when you run 28psi?What kind of primary clutch are you using? try bigger coils and im sure you will agree that you have got more power,already at 22psi than you got at 28 now..does impulse system compensate enough to run 28psi without water meth?Im sure if you use a stock primary now you can not be over 340hp.Give me a call when you have changed your coils 0014790729959 bjørn
