You wouldn\'t be when I\'m loosing what\'s left of my hair wiring these things up!!! :rollin But it does mean I get to drive them sometimes

I still can\'t put into words how fast this car is:3gears-lh

Wiring is easy, I\'m an electrician so doing stuff on a car would be less hastle than the work I do on site. All within arms reach and not the other end of a building when your trying to find a fault.

Surely once you have done it once, you have done it a thousand times? Lol

i prefer fighting torque type events standing start 1 mile runs , starting on concrete normally so not so much grip to break stuff , 200 mph is possible with big power (stevie turbo has done it in his supercharged granada ls3) ,and it does not mean the 60ft time mean so much as in 1/4 miles where a well prepared chassis make up good time and mine is a road car on road tyres, i am going to run it at the strip when its mapped properly but dont know what to expect :3Confused .

Lots and lots of tyre smoke. Hahahaha

Great build and interested to see the future of the 4 rotor build!

So what are we talking costs for each build, not looking for a figure really, but will they come out similar to each other?

With that power Craig, your terminal in the quarter will be easy 145-150, so hitting 200mph in your setup in the standing mile will be a piece of pi ss , cant wait to see it run should be epic.

i managed 180.1mph in a standing 7/8 mile with my old na engine , my mates cerbera with a 530 rwhp NA ls3 has just done 202 mph at bruntingthorpe , i think 200 should be easy and should have lots of power for good times just getting all down is the answer,it should be able to have varied boost depending on gear throttle angle etc ,with 13 psi springs in the waste gates it makes 13 psi @2750 revs at half throttle (the dyno could not read it but he said it was over 800ft lb at half throttle) ive booked in to TVR power in a couple of weeks to try and map the second half of the map . im running it with 4 psi springs at the moment and sort the boost control out for the higher gears .even at 4psi second gear is a joke (3.08 diff ratio) . im running 285 rears but can get 305s on which i am trying to get hold of ,

as for price !!! the parts are alot but i have spent hundreds of hours on it (about 10 hours for one 4-1 manifold ),about 30 hours on wiring, it goes on !!

Will66 · June 21, 2011, 10:47:28 PM

800 lb ft of Torque?

?? Sh*t the bed, you could tow start stalled trains with that!

fil_auto · June 23, 2011, 12:45:49 PM

Craig, FDUKin astonishing those figures!! Cannot wait to see and hear the finished article... hats off, lots of them to you squire ;o)

tinker-27 · June 23, 2011, 02:44:36 PM

i had a drive in it last night ,at 4psi and only mapped up to half throttle, it drive very smooth and normal at low throttle openings (90 mph is 1700 revs) but if you squeeze the throttle in second asa soon as it gets to 2000 revs it just smokes the tyre and the same in third :burnout, im on 285 federal rsrs which are good . it is going to need boost limiting in the lower 5 gears i think !!!!! . im new to FI so i have no idea how much 10 more will make ?. to be honest this is enough now , you can call me soft but i 4 psin with full throttle shoud be fun .

What petrol are you using? Blower I take it?

If you haven\'t seen any of nelson racing engines YouTube videos then I would go have a look at them if was you, they\'re just going through their LS series of engines. Think he has had 1800hp so far with race fuel at 30psi. His engine building and mapping skills are very good. All twin injectors per cylinder, one for 93octane, the other for race fuel.

Switches between the 2 depending on boost setting.

Go check em out, if you haven\'t already.

I think i\'d .... my pants with that much power, look mental. Congrats on such an impressive build, I\'d love to see a super car owners face when you leave them for dead.

Can i just ask if you are only running 4psi, if you had to do it again would you use a single turbo? I only ask as the car is obviously spooling up at low rpm so for a street car would a larger single be more drivable? (or am i talking boll ocks?)
