Idaho Tuner's 240/|SR Build thread

the reason for stiffer springs. i aksed the same question when i started my build.thisis the answer i got.

dang... you always want to cheap out....

valve float is why.

and here is his response when i posted waht i have now in my car

thats a pretty good setup actually. You dont need Ti retainers if you really want to save money.

With that setup Id set the rev limiter around 7.5k~8k.

Ti is lighter so it is more rev friendly but the stock retainer should be fine with BC springs.

[RCCC_DRiFteR]

swap the vins, thats what i did. its not hard and it'll be less hassle in the long run

Alright thanks WC!! How much did you put into your head Idaho?

[idahotuner]

how much money. i think i have about 1000 total in my head work and parts

When it comes to valve springs, material quality is always a must. But the main reason for "upgrading" your springs is exactly what you quoted Ben, to prevent valve float.

More specifically, to use a valve spring that doesn't "float" the valve at a higher frequency(rpm). Of course like everything on a car, there is a compromise. A valve spring that resists valve float at super high rpm might not at a lower rpm. That's why you sometimes see a "dual valve spring" kit. It uses a low frequency efficient spring to cover what the high frequency efficient spring won't.

Go to youtube and type in valve float, iirc there's some awesome videos showing a valve start to float and then float so bad it hits the piston. Cams spin half as much as the crankshaft does. So at 7000rpm, your cams are spinning at 3500rpms....thats a little over 58 open/close cycles per SECOND on your valves and springs. After acknowlegding that fact, it's pretty easy to see why valve float happens.

I guess that's why people pay hundreds of dollars for a piece of metal that takes much less to manufacture. Security.

[idahotuner]

that is some good info right there thanks alot.

[datsun2401972]

Np, fortunately my parents paid the 5 grand to send me to aircraft mechanic school where I learned most of that info.

[idahotuner]

nice. well i am one step closer to a huge update. i think it will happen sunday or monday night. i got some replacement parts today too. i will just let the suspense build lol

[DOHC20sr]

Naloos13 You need to give this man the respect he deserves. He has documented every part of his build. The only thing you can document with your "track car" is how much you paid the speed shop to build it. Dont be a hater, appriciate the pride a man has in his car that he built himself.oh and PS, if you have a fully built track car, you shouldnt have much of an interior.

thoro explanation datsun thank you. and thank you Ben

stock retainers are ok. and better springs are not a bad investment.

but I am better off If I have a higher revving head, that makes use of stiffer springs.

[DOHC20sr]

yea sorry idaho, i know im a little behind. i havent been on your thread for awhile. i just saw that and got a little pissed. BTW, everything looks great

[idahotuner]

oh its cooli like it when some one comes in dissing and everyone that is following my build thread defends me and i dont have to say anything.

it will look really good come sunday night

[DOHC20sr]

i wish i would have done a thread build like you did. obviously you have more patience. i'm looking forward to see whats next.

[idahotuner]

well i wish i had taken more before pics of my car. my last build i did. i cant wait for tomorrow though 1800 dollar pay check. about 400 of which is going to my car. YAHOO

[RCCC_DRiFteR]

All that info on the head is nuts!! Idaho did you do cams??

[Kalypso]

I also noticef that outside that garage is a sprawling forest of trees, that's nice scenery

[idahotuner]
