hahaa

 

not really as long as you fuel and timing is correct it can be done

lol yah with race gas and some LUCK..
it's a possibility..i guess lol

edit: maybe you didn't read the part on where he plans squeezin??

My cousin just gave me some brand new ctr pistons to play with, I believe the cr would be around 12.6-12.7 and I would spray a wet 50-80 on top. Does anyone have first hand experience with the same setup? how do you like it ? and do you detonate with 93 pump w the ctr pistons with out spray. </TD></TR></TABLE>

The way you plan on running the setup is wrong and will get you into trouble fast. Unless you can get the stand alone computer ( hondatat, neptune etc ) to make up for it when the nitrous is engaged. We have a motor that is on 13:1 compression and on 91 we had to reduce the timing to 6 degrees since we were using 91 octane. The motor took a 80 shot nicely when we ran race gas into it. it made 201 off the unit and then when the unit is engaged made 273 whp with letting off 1000 rpm before the normal redline. Do a little more research because remember it has to have a safe A/R to be run and with pupm gas that WON"T happen.

 

thats some nice power you made. What size injectors were you using? As i mentioned i am using a uberdata with a nitrous script and it will be tuned.
Evol , mmuller, onepoint6i did you all base your answer on FIRST hand experience or what happend to your babys mamas friends little brother. Explain why it would go "boom" tuned?

im in no way saying that high compression and nitrous dont mix..actually high comp. and nitrous are friends
So what cams are you planning in using? since its all about dynamic compression.
dont tell me b16..
You do know that stock pistons are cast right?
and PCT pistons are the worse for combustion quality and detonation resistance


it could be done nicely with forged internals, nice cams, race gas and nice tuning.
if you want it to last that is...if you dont care about reliability, then *** it give it a 150 shot

 

Since when have CTR pistons on a LS/VTEC bring the compression from 12:5 to 13:1 ?

</TD></TR></TABLE>It's all good that you got that tuning capablitiy you will need it. The injectors were 440's . The A/f ratio was around 12.4-12.8 something like that. The motor also has skunk stage 2 cams in it. The car has a redline of 9600 it makes power up there and holds it a little while longer and well with the nitrous we pull off around 700-1000 rpms before the original redline. Why I dont know we were just told too

good luck bro

 

I've been thinking about running the same exact setup except i'd run a direct port 100 shot w/ CTR intake cam. I think it'll work fine with good tuning but i am worried about the CTR pistons melting. You'll need a good fuel management setup like uberdata/neptune/hondata, without it...i dont think it'll work. Talk to your local tuner...if he can do it then get started. You have the advantage of running 93 octane while i'd be runnnin 91. Your setup is within reason so dont let these H-T clowns change your mind.

 

like i said from the get go of this thread as long as your fuel and timing is correct you'll be good to go, theres a few actual ctr motors running around ontario ca that know what i mean that have been built by me that have been running for a coulple of years now no problems

 

purpleterror not to get off the subject but that is a fine *** chick on your avartar if thats your girl no disrespect

good luck im thinking about juiceing my 13.4 lsvtec

 

i went 11.1@125 on a 84mm gsr 13.8 to 1 compression with big cams(which are also said to not be good for nitrous)
that was on a 180 shot direct port.. ended up spraying close to a 300 shot on it. car was making a little under 230 all motor and made 483 ripping the tires on the dyno with the juice...drove the car everyday to work and around town. went to the race spot every wednesday and to the track every friday. had it like this for over 6 months and the motor never let go. only reason i took the set up out is cause i went boost.

all the people who say u cant spray on high compression either #1 havent tried it
or #2 know nothing about nitrous and how to tune it...

 

hey cubish i need a lil help from you about a nitrous setup I also have Harv helping me with this

 

just hit me up and i'll answer what ever questions you have

the original thread starter wants to squeeze 150 direct on 12.5:1+ on cast pistons and stock rods ....

being that your @ 84MM your obviously on forged pistons=totally different than cast..

BTW: Nitrous = Compression in a bottle(a bit more complicated but its what it is)... Hey whata you know more compression loves big cams..who'da thought

 

I thought about doing something similar, but would much rather pickup a set of high comp forged pistons and rods to be safe.

 

why dont you ask 1700anddropping what his bottom end consists of... stock parts built bottom end. same with shant. and ive built quite a few high comp motors with cast pistons that held up on a 200 shot.

and thanks for the explanation on how nitrous is compressed air...if it were only that simple... boost is compressed air...are big cams boost friendly?

I never said nitrous is compressed air, I said nitrous=compression=big domed pistons=big cams=mad power

Boost is the opposite,obviously..

your engine explains it all,

big cams+nitrous= power

boost+big cams=pointless

explain to me why big cams are making power with your setup?
