AND I care.....WHY ?


AND I care.....WHY?

You think that is SMACK!?!
Once again I DON'T CARE and never said that.



Quit whining over words over the internet. You act like a damn baby.

 

Dude

That's not what I meant! It just points to the line that indicates which line is for which car that's all the lines mean. Just like CAI and Y pipe is not at 4800 rpm!

 

um....where shud i download the video?

 

 

I have the video and will host it. But I'm kind of swamped with some schoolwork right now so the video will be up later tonight to tomorrow.

 

that video is gone or something, i can't download it. is it somewhere else?

 

I like the dragon pic in your sig, looks sweet

Kirk

 

hehe! sorry I didn't see your post, you are right....only trying to show which line was which! Dunno, get the feeling Turbomax is kind a pi*sed off with me!

Turbomax, if you have a problem with me, let me know ... I'd like to fix that! If I offended you in any way, then I'm sorry. I am not so dumb as to believe that s/c come to full boost at such low rpm.

one thing, the 260+ HP on the "stock" supercharger seems a little high to me, just looking at these dynos. These guys are running 10 psi and getting 270 without intake. The stuff you quote, is it wheels or flywheel?

Nigel

 

I think most of the S/C'd maxes that are dynoing that high have a CAI. . . I know Kev, Jane, and Cheston all do (At leastI am pretty sure of Cheston), don't know about the East coast guys, but I think it is pretty common now.

 

Did I say "less volume of air = more power" ? Not sure that I did, but if I did, that is not what I meant. If you have more air and fuel in the same volume (in the cylinder) i.e. denser, you get more power if combusted correctly....I think that you had alluded to that in your comment.

By the way (not a flame) but boost is not necessarily measured in psi.

 

Actually, I meant variable intake ...

 

Its all good. Im stickin' up for the man

Kirk

 

Hehe! you're right again. The choking exhaust is slowing down my impeller at higher rpms. There is probably at least a good 10-15 HP right there .... at least! I have toyed with the idea of just disconnecting the exhaust and seeing what it will put down. Back pressure would be less of an issue for the engine cos the turbo is there. Turbos do not like back pressure! 10 psi of backpressure reduces your boost to almost nothing! With a 2 1/4" pipe (I think that's stock) and the restriction near the resonator, I would not be surprised if the backpressure was pretty high!

If there is no restriction, the impeller should also be able to turn more freely and boost should come on faster too! (I am not certain about this ... my tuner tells me) once the pipe is on, I can start turning up the boost.

 

Sorry, well Kev has a variable intake, although he is pushing 285 HP at the wheels with an auto and a 3.125 pully.

 

Thanks for the info! I am looking for stock s/c dyno on a 5 sp ... I really would like to know what those run at! I would like to have the dyno sheet for an overlay.

 

no we're koo, that was my bad on the dyno graphs. i misinturpeted what you were trying to say. Dont get me wrong but i do think that you are trying hard to push the turbo kit and saying its better then this and that, but im in no way upset or mad. for example: BOLT ON turbo kit? i dont think so....
oh, my friend Lynn dynoed 269 at the wheels on a 97 Max 5speed, supercharged(stock pulley) and Ypipe.
Cheston dynoed lower then other 5speed Maximas, even he tinks something is wrong with his Max.

 

Hehe. It sure seems that way! I still stand firm on the fact that it IS bolt on ...that's just cos it is! unfortunately, it only bolts on to 5 sp right now.

better than this and that? I am not the only one saying that... I always like to compare stuff .... it's human nature everyone does it! This WSP pipe is better than that Stillen etc etc... I'm also really excited about turbos! I have read up a lot on them in the last few months. It is the cheapest per horsepower gain that you can get. Superchargers are the only thing I can compare to ...it's the only other form of boost ... apart from NOS (loosely classified). Like I said everyone likes to compare stuff, and I have had so many requests for Dyno sheets (before I posted my dyno sheet). Even then people don't believe the numbers! Well, I am enjoying the car ... it really stokes me when people don't believe you...and of course I will argue back!

I would like to know some advantages of the s/c kit over a turbo. The only thing I could think of was turbo lag ... but I found out some time ago that s/c don't build full boost until almost red line. I really would like to take a more impartial view...but just don't see it. The s/c would be marginally easier to install... compared to non-intercooled turbo.

I would like to give you and everyone a brief description of what was involved in the kit (non-intercooled)

1. remove y pipe
2. remove/relocate battery to trunk. relocate relay box #2 (moved slightly)
3. install custom CAI. (similar to PR CAI) remove all stockbox components.
4. Bolt on wastegate to custom y pipe
5. bolt on custom y pipe to turbo pipe
6. bolt on turbo to cat pipe.
7. Bolt on turbo
8. add T fitting to oil pressure switch
9. screw in oil feed line to T and run up to turbo
10. tap oil return (mine is in valve cover), though upper aluminum pan is better. (This is probably hardest part of install if you use aluminum pan)
11. run oil return hose and clamp
12. Bolt on FMU and run to fuel return line. Tap vacuum line with T.
13. tap vacuum line with T, and feed vacuum line to wastegate. zip tie connections...vacuum T to boost gauge if available.
14. Connect CAI to turbo. use regular clamps on CAI to turbo compressor side.
15. Connect compressor output to throttle body. Use T bolt clamps on the compressor side.
16. Ensure vacuum lines do not touch HOT exhaust.
17. highly advisable to have boost gauge. When engine is on, rev up slowly to ensure that boost level is not too high.

so which part is not bolt on? Well it depends on whether or not you want a BOV and what type of BOV you want, that may require some welding. If you specify BOV and purchase it as part of the kit, then it is not an issue.

I am doing all this from memory, so may have missed a step, but fundamentally almost everything is there.

Nigel

 

#10. tap oil return line to valve cover or oil pan, that is NOT bolt on. If you rmeove it you have a hole in your valve cover or pan.
for the intercooled kit, half of your front bumper support was hacked. that is NOT considered "bolt on". It wouldnt be that great getting into a minor accident in the front either. We didnt have to hack my front bumper support, im not sure if the 95 97 bumper supports are different or its juss cause of different intercooler. Technically a CAI is not bolt on but we wont nitpick that.

 

I thought he was on the 3.48" when he put down 269?


Jane dyno'ed at 230 hp on a stock SC pulley (3.60) at 6.5 psi... automagic.


Nice video, Nigel.

 

Since this Turbo kit is ONLY available for a 5 speed (atleast for now), let's understand the 5-speed supercharger options a little clearer.
--For 5-speed 97-99 Maxima's with supercharger & Y-pipe:
Stock Pulley (3.60") - 240 HP.
1 size smaller (3.48") - 250 HP.
2 size smaller (3.33") - 260 HP.
3 size smaller (3.25") - 270 HP. - Be very careful
4 size smaller (3.125")- 280 HP. - You better know what you're doing.
5 size smaller (2.87") - 290+ - Nice way to blow engine & tranny.

Is my understanding correct?

 

I guess my definition of bolt on is different from yours. In my threads, I have said that if you can install a CAI, you can probably do this too! So, do you consider the S/C bolt-on? You need to shave part of the alternator, I believe. Plus, I said non-intercooled. Accident, well that's too bad. A lot of cars I have seen with aftermarket intercoolers have them mounted there ...it's the best place for airflow. I worry about it too, but if you worry too much about it you would never do it. If you worry about vacuum hoses coming off, you could blow the engine. My intercooler is very big. It is possible to get small ones to sit under the bumper, but they're just not as efficient.

Further to you thinking I am pushing the turbo too much, do think my claims are incorrect? I would like to know if I am wrong so I don't spread incorrect information. I am trying to let the numbers speak for themselves.

Nigel

 

This is excellent information. Just wondering if you know this for sure or from other people cos it doesn't jive with Turbomax's numbers? Also do you have dyno graphs?

Thanks

Nigel

 

That is more or less correct.

Matt has the highest "known" hp output... 3.125" ~ 277 hp (?).

No, you don't need to shave the alternator.

 

It won't affect the turbo nearly as much as a n/a car. The biggest application for turbos is on prop planes to compensate for altitude, and I hear they can fly OVER Colorado.

 

Nigel,

First Great job.

Second- dont let the haters get to you. I go through the same thing with my f150 (blown) making More HP than a lightning. People were at the dyno shop and saw it spin up, yet they still scream foul saying the dyno is off. Funny that a stock L spun up behind be and made less HP.

Third- I want one. Can you send me pics of the install and what had to be cut etc. for the cooler. I am in the process of building my motor (rods, pistons etc.) and would like to do this all at one time. you can shoot them to me (pilot@skidmarkracing.org). I also need the "out the door price" for everything (cooler, pop-off etc)

again thanks dude and great job

 

I put a turbo on a 240Z back around '77, when the kits first came out. No BOV readily available back then, so just exhaust back pressure to control things. I was running about 10 lbs. of boost and you could feel the engine choking. One day we cut off the exhaust and hit the freeway. 18 lbs of boost before we backed off from pre-detonation; no intercooler, no water injection, just straight boost, baby! Hold on!

 

OK, now see, contrary to what you might think, you're not correcting me in any way. If you'd read further into that same post of mine, you'd find that I said that with a turbocharger, you can be more conservative with the correction factor, which in the case of a turbocharger, varies between .5 to .8 seconds, as opposed to 1 to 1.1 seconds for a naturally aspirated vehicle. Again, that correction factor depends on the efficiency of the turbo system. If you have an ineffecient maxed out turbocharger/intercooler/engine, then the correction factor will be at the high end of the spectrum. Quite the opposite if the turbocharger/intercooler/engine is efficient.

Contrary to popular belief, any old turbo on any old car does not make it as fast at altitude as at sea level.

 

Preach on, bro!!!

Kirk

 

This is the best I could get so far. I'll continue to look.

your information is correct for the most part regarding the horsepower figures. maybe you see bolt on differently but "bolt on" in mind as well as most of my friend's shops and etc is no permanent modification that will affect the car. Basically a hole in the valve cover is NOT BOLT ON, nor is the bumper support mod. I dont know the dimensions for your intercooler but mine is a fairly large size and i didnt any of the bumper support, only 2 bolts onto it. Remember this, bigger is not always better when it comes to intercoolers. CAI is technically not a bolt on mod cause after you take it off there is a hole in the car but its all the way in the corner not seen and shouldnt affect anything on the car so its sorta borderline. shave part of the alternator for supercharger install? i dont remember that when i was installing one. i rmemeber there was slight shaving of the fans.

by the way, this is juss constructive arguement so dont take anything im saying as a flame cool?

 

230 with GReddy cat-back and SC.

 

thats a lot of searching!

 

sorry guys...but i couldnt find the link to nigels turbo...please send me a link!!!

 

I put it back, if it goes over ya'll gonna donate!

 

I have the video mirrored on my site as well.
