If you need the Teins I have a second hand set on offer...and we supply bosch fuel pumps
 
Why do you need a turbo timer to hit 10s?? lol

[MARKPRIOR]

lol just copied it off the for sale ad

thats my current spec just after what if anything needs replacing to hit the 10\'s /500hp+

I heard the Alpine Head unit, is at least a 10bhp gain !! :spank:spank:spank

[Ed_RX7]

now now boys....1st is to get a bigger turbo....some drag radials. Diff, braces etc!!!!

[m4drx]

you need alot more than power. setup is everything. weight, grip etc etc

[MARKPRIOR]

well decided i am going to have a bash at it all things going well so will be out to pick brains etc.....

[hairyhoover]

It\'s not all about power matey!! Somebody in the states got there on standard ports with a small gt35r!

[MARKPRIOR]

so deffinatly possible with what i have then, good to hear

[BlitzBoy]

yes you will need to have roughly be at 530bhp to 540ish at the Flywheel. So about another 50 hp on what you have now, so you probably need to be running 1.4 to 1.5 BAR boost.
You will need softer suspension,tein RA are track focused dampers rather then Drag,drag spec tires,a clutch type diff,diff brace

[BlitzBoy]

and loads of seat time to get it in the sweet spot for a 10

[MARKPRIOR]

ooo looking forward to trying thought the suspension would need sorting, am i right in thinking i need a nice soft rear strut?

[BlitzBoy]

you need to change all four coilovers and springs to a soft drag spec, like HKS Drag coilovers or they are companies that can build you some coilovers for Drag and soft springs. This allows the car to squat and stay squatted for the launch, this helps minimize wheel hop, improves grip, lessens wheelspin. You need to budget about £1000 for it

On my FC - although its not a 10 second drag car, it has the stock springs and dampers - comedy suspension setup as its so soft lol but ive found that this helps get the power down and im aiming for 13s at the next meet whereas someone with the same power (and indeed more) with harder suspension can\'t get near my times lol

You talk about how much power you need for this and that, you can have 1200bhp from a 20B but if you can\'t get the power down onto the track then its pointless lol

Also bear in mind that IIRC, a saving of 1kg in weight is equivalent to 1bhp in power-to-weight ratios which will help you no end on the strip.

If you havent thought about it already, i\'d consider putting your girl on a diet!!
