rev210 do you have any dyno figures? I'm not understanding much of what people are saying in this thread i only understand dyno figures :)

Im extremely interested to see how you go with this whole plan and the other conversation is interesting.

Maybe someone could workout what my HP is at the fly/rear as I dont know what the conversion is.

Heres my mods

'95 Series II

FMIC (Micks Metal Crafts)

HKS Pod Filter

3" Custom Front + Dump Pipe (1 pipe)

3" Hiflow Cat

3" Nismo Cat-back

2 Stage Boost Controller (7/12psi)

Stock ECU

Stock Turbo

203 rwkw @ 12psi

Dyno Printout

Blue = Yesterdays Dyno Run

Red = 3mths ago before rest of exhaust etc.

I don't want any more power for the time being I just want to improve launching capabilities (Nismo Suspension which I think needs to be re-setup) and maybe some wider tyres (currently using Falken 225's/16").

I would LOVE to jump on the drag strip down at Eastern Creek but at the moment I'd be too embarressed to either drop a burnout or just axle tramp off the line.

Would be awesome if you could do dyno runs after each mod just to see the small increments of rwkw your gaining out of non-standard mods (By non-standard I mean not just whacking on a big turbo and fmic like 99% of the people on here do).

I've realised that different cars can make huge differences in performance and power with very similar mods.

benm,

It's good to see the power improved with the new zorst. The thing is rear wheel dyno's are for tuning and not too good for comparison.

I can tell you that the std turbo can't make any more than about 300HP at the flywheel, if you have a std turbo you would be making less than 300HP at the flywheel.

No one cares if you wheel spin your way to ordinary times, its alot of fun to do and hey learning is something you can only do at the track. The more practice the better you get.

225's are good its 2inches more rubber than I have, worth giving it a shot. let them down to 19psi when you go to the creek.

Have fun!

turbomad,

thats why I don't get all ga ga over rear wheel dyno figures.

If I take my car to Myaree Dyno over here I'll probably get more than 300rwhp (it's a dyno dynamics dyno too). I wouldn't have any issues using their dyno (high readings aside) because I wouldn't be there to get figures to brag about, I'd be there to tune my car.

It's not a case of 'hence 300+HP at the flywheel' if you work backwards like that you often wind up with a bulldust figure that you can't back up on the street or track for some strange reason.

best leave the rearwheel dyno charts with others from the same car and dyno.

Dyno's are for tuning.

Which is the reason why I asked if you had any dyno figures so I could see what sorta power you are making so I know what sorta power is required to physically power the car to a 12sec pass.

I think it would quite easily be 75% power and 25% driver talent.

HKS exhaust cam gear has arrived!

And I have given the S-afc II a bit more tuning last night along with some timing adjustments, I think I found another 5 hp.

I will get down the plex' for a test as soon as I get the cam gear on.

12 seconds here I come!

How'd ya' measure that 5hp rev? With the good 'ol Arse'o'meter? ;) Sorry mate had to be done :(

I'm tipping you'll be making it into the 12's very soon. I'm heading back to AIR this weekend, see if I can't get myself another low 13 with 115mph TS.

yeah with the ass 'o' meter, then again it could have been the chilli and guiness.

As long as you do a 1/4mile long burnout it doesn't matter what time you get.

Why don't you get hold of some AZNU ozrace tyre treatment for when you go down mate?

Chilli & Guiness! Hell just back that arse out the window & it's good for .2 & 5mph ;)

In all seriousness I "shouldn't" have too many issues with w/spin, as the RE540S's hook up 100% better than my old Falkens ever did! A 2.0X 60 is my goal, nothin' too extreme.

"RE540S"

What is the brand and specs of these and approx do they cost ?

I have Falken 225's on my car all round and I certainly think their is more traction to be gained with a better quality tyre.

benm,

The RE540S is Bridgestone's road legal competition tyre (semi-comp/semi-slick) is has minimal tread grooves & is designed for circuit style racing. It has a very stiff sidewall (one of the stiffest semi-comp's) so it doesn't really suit drag racing, however due to the very soft tread compound it gives awesome grip levels (both straight line & corner).

As with any competition tyre the RE540S needs heat before it gives it's best, has very poor wear rates, is noisey as hell & picks up every little stone on the road ("tink" "tink" on the inner guards)

For my needs I found the RE540S's grip levels, cost & all-round nature of the tyre (wet weather grip I haven't tested yet) to be unbeatable :)

RE540S - Re540-dack.jpg

It comes in a range of sizes from 185/55/14 to 265/30/18.

My rear 255/40/17's were $310ea front 235/45/17's were ~$280ea

benm you're right, i have falken ziex 235front 255's on the rear, the engine is stock and it spins so easy. my old 33 had exhaust/filter, and 225 dunlop fm901's all round and it gripped so much better.

/me has Falken Ziex ZE-502 - 225/50/16 on all 4 noooo

Think I might go and rip afew donuts in my street to force myself to get some new tyres.

These things are absooooolute rubbish in the wet, I can't even roll around round-abouts without getting the tale all excited.

I still think they have a solid 4mths+ usage tho If I keep the rears spinning at the same revolutions as the front :)

Works Auto.

They flow enough for mid 13's all day on skinny little tyres, without any fueling adjustment and extra weight in the backseat.

The power has been increased since the last mid 13's meet. And the torque will see a further rise with the exhaust cam gear.

I am confident there is more than enough power flowing/squeezing throught the std turbo and cooler to propel the whale over the line in under 13sec .

The trick will be the 60ft. With a 2.1 I will get close, 2.0 or lower will see me safely there.

If not there are a few other things I'll resort to. I strongly doubt the turbo or intercooler will need changing at any rate.

Rev210 is also a smart guy (I've been following afew of his threads and reading his comments).

It doesnt take a HUGE front mount and a HUGE turbo to make good consistant power to get you down the 1/4 Mile.

I would say (from a non drag racing mind) it would be something like

40% driver

30% engine

20% handling setup (susp + tyres)

10% track conditions

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
