Mate thats an excellent idea... I hadnt thought bout that but i will definitely buy a 6.0l and start with that..Thanx

Ryan always thinking! Make 1000+ wheel pretty easy with one of those and the right combo. Just heavy.

I may have missed it but what are you gonna use for boost???

I don't know if LS3's are expensive over there but that and a D1X and you'd be over 1000. Look up Detoxx on YouTube. He's been 900+ for years on an stock long block LS3. They are one bad motor.

Going to use twin turbo. Lots better for circuit. A guy who used to tune my car wanted to go do a few 1/4 mile runs but his good engine was gettin repairs so he put a stock ls1 in with his big turbo and was into the 9s This with his stroker

Awesome. I don't know the benefits of a twin system vs single turbo. My one buddy runs 7.6 in the 1/4 and swears by a big single. He says you don't need twins until your back pressure is too great for a single.

My boosted car is an LS1 but it's a forged 383. I let off at the 1/8 and coasted to a 9.3@117 lol

Ive been having odd electrical gremlins since i put a new engine harness on. oil pressure fluctuations, ambiet and iat variations, maf all over the joint.
So i took it to the auto electrician, i hopeless when it comes to electrical. The outcome was the same as the last 10 or so places ive taken it for work to be done. Charge me a sh it load, do stuff i didnt ask for , and car comes home not fixed.
So i can add another string to my bow, auto elec. Went right over harness and found broken wire for crank sensor, wires touching on an injector, map wire broken, alernator wire hanging on by a thread... All fixed..... How can a professional auto electrician miss all this.....
The only place anything will get done on the car now is upholsterer, engine machine shop, Everything else ill do, no one else gives a flyin fark

Just thought id update since last post. I have a property in the country , 100miles from home. Started building a house there so been up and back 4 times a week , so 800miles a week.
Cars been running great, replaced engine oil with driven gp-1 15w40. Been towing a trailer on occasions, dragging people at the lights, did a pb in time to country property, bit of speedway action in the paddocks, best mileage ever to property 18mpg, it gets revved to 7500rpm everytime im in it.
Goes for wot tuning next week, flex fuel sensor going on so i can run e85. Starting to warm up here and im close to maxxed out on 98 petrol
Had a small oil leak that took forever to find, one of the braided lines going to oil cooler had a pin hole in it.. only issue ive had..
My guess for hp on e85 will be 695rwhp

Can add one of the new Nissan GT-R"s to my conquests. Cocky bastard, he got a good jump on me but by the time I got to top in 2nd(sideways) was up on him then he nearly smashes into me coz he thought he would hv been miles in front. Had another run , roiling in 2nd, he grabbed 3 lengths but as soon as I got traction I just cruised by....NEXT

Nice kill! Those GTR s are 11.5 sec cars stock. Id imagine even with alil more boost, awd, and some tuning they must move out pretty good. Id love to own one. But id feel better puttn a whippin on one too!

he jumped me real good , thought he was gunna get away but as soon as I got traction I came up on him quick, be great to see wht would happen higher up in the gears. I hv 3.45s so on the road can only get into 3rd for a bit before you hv to get out of it.
The weathers warming up here in oz and my temps are climbing . I had a small oil leak so missed dyno this week. New booking is Wednesday week so will hv before n after on e85..

Good to hear.
Would you say, when it comes to overtaking, would the 3:46 gears be quicker than the 3:91's?
I look forward to those E85 results.

Add a Maserati to the list haha
ive been busy building new house but this Thursday’s dyno day. Flex fuel sensor will b installed , along with some new injectors, changing from fast 60lb to Bosch 1080cc. I’ll video dyno with 98 fuel then again on e85.
Any guesses 98 v e85?
Took the car out for a shakedown to see if I could break something before hittin the dyno. All went good , sort of, smashed a Maserati along the way. Got home shut it down and heard some hissing. Pin hole in top radiator hose. Not bad seeing tho it’s 13yrs old.
Replaced top n bottom hoses, double clamped both and good to go. Done 2000miles since last post and it hasn’t missed a beat

Might be time to ditch all the rubber lines and go braided with AN fittings on everything.

Seems like everyone goes for the highest flowing water pumps there are. On a mechanical pump the flow is dictated by engine rpm. When your revving your motor as high as you are, you are most likely cavitating your pump. The other problem is when you go to low rpm you loose flow. Also if you are moving the coolant too fast through the radiator, it will not cool efficiently. The rubber hoses are too big for high rpm. Most always when you wind that bad boy up and let off your upper radiator hose will collapse and cut the flow back to the block. Go to a -16 3/4" braided and it will slow it down enough. The old school guys would loose the thermostat and put a washer in there with a 3/4" hole to slow it down. The electric is really the way to go to keep everything flowing the same at any rpm for maximum efficiency. That Mazere 55 gal is more than enough with -16 hose and fittings. Great quality pump that will last for years driving on the street. Its crazy but our car actually cools off going down the track. Don't even turn the fans on till we go through the traps. Never gets over 180 on a 100 degree day. We run a 160 thermostat and usually if the temp gets up to 170 staging. It will be back down to 160 going through the traps.

Those meseire water pumps work really well.
I have one in mine.

I’m running an Evans mechanical pump, outflows all electric pumps .
my understanding is slowing the water flow is old school theory . A faster flowing system will out perform slow flow. My system goes to 188f and stays there.
Yesterday my oil temps sat on 270f for 15 mins and water temps didn’t budge from 188f . I’m also running a 32lb radiator cap which is probably the cause of the pin hole . I use it more for safety. The reason for using a higher pressure radiator cap is it brings the boiling point of water up, once it boils , thats steam , steam has no cooling properties.
A pair of braided pipes would be better in that it would stop the expansion due to pressure but I thought 13yrs was pretty good life
