A search on 'Hyperco' turned up almost nothing. Anybody know if a P10 has the same springs (physical dimensions) as a B13 or B14 sentra?

The Hyperco springs are getting awesome reviews and Mike Kojima helped Hyperco develop the Sentra application.

There is an excellent group deal going on in the sr20forum that I would definitely sign up for if they will fit a P10. It will be open until they can get 25 people to pay... $299+shipping

i'm pretty sure you couldn't put a b13 spring in a g20 even if they would work for the rear what would you do for the front? hyperco isn't making b14 springs.

hang on to your cash.

i may be doing something in a few months

The guy who does the b13 group deals is a friend of mine and he told me a while back when I asked that if we came up with 50 orders they could make a set of p10 hypercoils. I don't know if that would ever happen b/c it seems most p10 guys are more into looks than performance and would rather just pay $100 for some tein springs...

Well some P11 guys are willing to pay for H&Rs for performance. Strangely no P10 guys seem to go for H&Rs.....but yep I see a lot of guys getting Teins.

$300 for an awesome set of springs is nothing at all. I would spend that in a heartbeat. 25 sets I would be optimistic, but 50 pre-orders? That's a bit much.

But yeah, I've noticed that G20.net is 90% show and 10% go. What rocks about the Sentra, NX, 200SX forums is all the info on actually making the cars perform.

Is your comment an insult towards this forum? Sorry, maybe I read it wrong...

I think 'insult' is overstating it a bit. But to your point, yea, reading "Yo, would these rims look good on my ride???" kind of posts is way tired.

I've been lurking for quite awhile, and finally decided to step up to the plate and become a sponsor. Not because of what I will get, but because of the info that I already have learned from the forum. It's a good place; that's why I spent the money.

I noticed you have over 3100 posts... are you already a sponsor, or still deciding if it's worth it? Or do you automatically become one when you're 'Featured Member of the Month'? Apologies for taking a dig at you here if you are a sponsor.

By the way, in all seriousness, I dig the all black look on your ride. That's something I would do, and it stands out from the carbon copies. And damn, that turbo... if I had any way of getting the car to pass a smog inspection I would have it. Seriously envious.

How to tell a sponser if they have changed to a custom title.....red text for their name ;)

And having to start every post with "I searched already but...." just to keep from getting flamed over on sr20forum is tired....

We're all interested in the SR20 so let's not go down that road =)

btw where is Dave's turbo ?? :surprised

I was wondering about the 'sponsor' title. I dug into the profiles a bit, and couldn't quite figure it out. Thanks for clueing me in on the red title.

Regarding the turbo, or lack thereof... this will surely teach me to think twice about posting late at night! Got a couple cars mixed up... crawling under a rock now.

i pm'd chris about going with a different manufacturer. he said he wasn't interested

i can get them built in as few as 10 sets (for less money too)


-chuck

When you say 'as few as 10 sets' I assume you are not talking about the Hypercos. What manufacturer are you considering?

I owned an 91 SE-R before this. SR20forum is a great site. I had the Hypercoils on my classic. They are great but it is a brutal ride. I had koni bumpstops, Kyb AGX all around. But if performance is what you want, these springs deliver the goods. The SE-R took corners like it was on rails and you wouldn't believe how well it handled usless you drove it. I cant imagine how well the P10 would handle.

I might be intrested in a set. Also as a former b13 SE-R owner, (2 91's) im looking for something on the performance side for my p10...:thumbsup:

not hypercoil - i made a few contacts at sema

sooner or later i wiil be having some made and branding them as mine

pricing would be $200 a set - if i could get 10 deposits, i could probably get them done in 8 weeks or less

anyone have any idea what they should spec out as???

drop f/r - rate f/r ???

Hey Pears - don't wanna hijack your thread so I've PMed you.

Thanks,

I also had the Hypercoils on my B13. They were excellent - I didn't feel that they were "brutal" at all, whereas the Eibachs I had on my B13 before, and the Eibachs I had on my P10, had a very rough ride IMO.

I'd say any custom setup would be better than what's available. I've been thinking about Teins after riding in a Tein/AGX equipped P10 and finding the ride much more pleasant than the Eibachs, but then, I've been thinking about getting rid of the P10 for another B13 too.

I'll be following Chuck's spring intro with interest. My opinion would be about a 1.2" drop all around and slightly higher spring rates than the B-chassis setup, which is 300f/200r, to compensate for the P10's higher weight. That would need to be tested of course.

Well first off the rates are gonna be completely diferent as the front multi-link on the P10/P11 has a different motion ratio than the MacPherson strut on the B13 etc...


I still haven't found anyone with that info for the P10/P11. Chuck is it something you've looked into ??

i haven't looked into much besides costing them out

i've got three products going right now and this is one of the six or so that are waiting in the wings

i think on my shigspeed setup we are running 300# f and 250# r really stiff but the koni's control it well

from what i understand agx's are only good up to about 300#

a good comprimize may be 225# front and 175# rear with a 1"-1.25" drop

wouldnt a compermise like that put you back in the TEIN range?

maybe, what are the tein rates?

i was just taking a guess

anyone have suggestions for the rate/drop?

P10, 151lbs front 140lbs rear
P11, 184lbs front 246lbs rear

That's a lot of difference in the rear :surprised

maybe 200/200 would be good for the p10 and 225/275 for the p11?

the front difference is interesting to me. are the p11's more nose heavy? use a different (lighter) sway bar?

the difference in the rear is because of they are not struts as in the p10 and are mounted more inboard at more of an angle.

here's some cool calculators

alot of spring rate talk, thre all using GC's but since were choosing our own spring rates it still applies

the lower shock mount is inboard of the balljoint

try again :p

It's a calc Chuck, it incorporates the angular compensation and motion ratio multiplication to get wheel rate from spring rate.

I don't have the measurements :( I just left those figures in so it didn't look like I'd measured anything ;)

It would probably be easier with our setup to physically measure hub travel and spring compression to get the MR.

tricked me :zoinks:

i thought you were making cacalculations and that was the result - duh

-chuck

Hehe....

I added a bit for MR measured via spring compression:hub travel on to it....

So when you gonna measure it ?? :p I wonder if Nissan/Infiniti could tell you the figure ??

P10:

325# 1.75 drop front

275# 1.50 drop rear

mark you have posted earlyer about p10 guys wanting h&rs I have been looking for them and can't seem to find them. Their web sight does not even list them

They are listed on the needforspeed website Mike....

http://www.needforspeed.co.uk/pages/sbv_pl.asp?Vehicle=NSPRI01&PartType=SUH03

HR-29-814 Hatch 2.0 petrol '90-'96 35mm front and rear drop.



Back to the motion ratio. I have done a little measuring on my old car, the only problem is that it's on four axle stands and has no engine/tranny in so the suspension doesn't compress much before it lifts the body off the stands.

I measured from the top of the spring down to one of the brackets near the lower bolt. I also measured from the top of the hub to the wheel arch.
I then jacked it up as much as I could before it lifted and remeasured the distances. The spring compressed 13mm and the hub moved 15mm. I really need more weight on it so I can compress it more and do it in the daylight so that I can check the hub movement I'm measuring is actual vertical movement as the hub is slightly inboard from the wheel arch.

So up to now we have a MR of 0.86667. The spring is mounted vertically as far as I can tell.

So now my 391/280 is 338/280 so a front wheel rate of 1.2 x rear wheel rate.

thanks mark have sent them a e-mail. hopefully i can get for a good price
