Unopened Class

[blueboost]

Thanks Craig and Nick, Nick, my idle is still inconsistant, but I did improve it a bit by increasing timming at idle and just below, and a fraction richer, and closed the plug gaps to .8 from .9. this all seemed to help but I think is only a bandaid. I checked all my connections, and some other things, but could not find a fault, On my last post I did not mention that I have my cat gutted to, and I feel this could be a bit of my problem at idle. I think the oxygen sencer does not get a clear signal, so it leans it off too much and creates a missfire. I will try a better flowing cat on it soon and see what happens. thanks for your help to nick.

I went to a street meet on friday night and my xr6t ran a new PB of 12.014 @ 114.55 mph, it ran a 60ft of 1.77 on that run, but the run before it ran 1.74 60ft so an 11 is there for the taking. so close to a 11, but so far, I have to drive 650 klm round trip to go to the drags so it is a tease to be that close to a 11. anyway my tappet cover has never been removed at all, (standed springs) and did it with pump fuel on street legal radial tyres. is this the quickest time for an unopened xr6t.       I raced gtr's and wrx's and supra tt's and someother v8's and it wipped them all. an xr6t is now the fastest street car in Mackay (running pump fuel and street radials) and 3rd over all on street (Two above me run on methenal)                                                 GO THE T

that's a great time hopefully you'll be able to get an 11 next time out.

What sort of tyres were you using and whats been done to the auto. What other mods do you have? What sort of power do you have cause that's a great 60', whats your secret???

Geea.

Thanks Craig, Last time I put it on the dyno it pulled 274kw, but played with the tune myself since a bit and put a cat back twin 21/5 inch exhaust on it, it has a pwr intercooler on it, injectors fuelpump and exede, I have a 3000 stall and I ran micky thompson street radials on it, I run standed air box with a could air duct going under light, it had bp ult in it, I would gess it has about 280kw now, and it runs 12 psi boost, but on gear changes it spikes to about 14psi for from the extra load, the convertor and the tyres are the reason for the 60ft time. the auto has line pressures lifted and the convertor, but also has a oil coolerfor the trany. I think Craigs old car ran about the same mph (115) with about the same power (280 I think) and it seems this power is not over kill for the auto with the line preasures lifted, (so far any how) I am hoping to go back to the drags next weekend, and it is a proper meet, so the traction might be better, (I broke traction a when I stalled it harder, I think it could have a 1.70 60ft in it if traction permits.) I have set my car so to lift the hood, it looks standed . I forgot to mention that I put a 2 pound extention spring on the wast gate to stop it from getting pushed open from the exhaust preasure,(because of the standed inlet pipe work restriction. (it did not want to go over 10 psi without this) air fuel ratio is about 12.4.

I would like to thank this Forum for the imformation that has lead to my car going this hard, and I hope what I have told you helps someone else.

Hopping for 11's

David

Well done mate... Im running 118mph at 11.9 but 60ft was 1.99 due to no stall converter and still running standard cooler .... So there is a great chance that you can hit into the 11's

Good luck,

Rob...

Thanks Mr turbo, I would like your MPH (118) but I think that is valve spring country.
