High compression pistons, larger bore, balanced bottom end, stiff valve springs, aftermarket ecu, higher rev limit (assuming it is still making power)

with an na, you have engine capacity, head + ancilliaries flow, and rpm as your basics.

So if you had a 3.1/3.2L spinning to 7000rpm......

(going to a larger bore may not be a good idea, i dont know, im not an rb30e na tuning and motor building expert. its a good idea but i dont know if it will hinder the engines ability to rev or something)

my rb30e is getting a bit sick....

how much did each of your mods cost, who did it, what exactly is the mod, where is peak power, whats the powerband like etc???

the cam is a SURECAM (btw surecam make all the cams for chiptorque, and for the rb30 hp1,hp2,hp3 it's the same cam)

headwork was also done by surecam. double springs, lifter boxes machined, port-n-polish.

104rwkw's on the chiptorque dyno, power comes on strong 2500-7000

without n2o or turbo!

Turbo is probably the best bang for buck though! can probably pick up the bits you need for under $1k, and run low boost (6psi or so) on standard n/a block without too many dramas.

or the twin cam head conversion also (may as well get a turbo head put on if you're doing that).

let us know how you ran at willowbank?? i heard something about a 15.2 or something worse then previously..

went to willowbank and only got one run in. there was a huge storm and the event was cancelled. heaps of wheel spin and ran a 15.3.

got it tuned at chiptorque, not a lot more power, a little more topend.

the single afm is the holdup, once i get enough $$$ i'll install a mircotech.

with this setup as is i should be able to run quicker than 14.8, but with the tt/b's i have lost some bottom end power so i'll need to change diff gears....maybe

next time i go out to the track i'll put on some 14's and run standard rear suspension, should help the traction probs.

not enough!!!

it was only 4rwkw's, the total cost of the tt/b's was $200 plus dyno tune. so about 400 all up!

i really need to piss off the standard airflow meter! i was thinking...hole in the bonnet, round air filter, bonnet scoop.

BTW......for those that dyno there car in 3rd gear, i made 108rwkw's in 4th and 128rwkw's in 3rd.....

4rwkw?? that's bugger all! I've seen way bigger improvements with an XF throttle body conversion than a twin throttle setup. How was your torque? improvement? I noticed more torque with the a twin throttle setup then outright horsepower. but then again, I think the twin throttle setup is more wanker factor than anything. When you going out next?

Had my car dyno tuned (again) on the weekend. Told the operator to do a run in 3rd gear and another in 4th gear, made 1-3hp difference between the gears (less hp in 3rd). Don't know where you get an extra 20kw from changing a gear?!?

i had it dyno'd at chip torque by Lachlan Riddel (the owner) so ring them and ask him.

Should take the car down there just for a couple of power runs and get a comparison. I was told it's more than likely the way the dyno has been calibrated.

Anyway, I've been told not to reveal my hp figure but I'll be honest with you, we did loose hp but we always knew we were going to with the mods we did.

    • 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.
