im gonna rebuild my xc fairmont and i wanna get it to do a 1/4 mile in 11 seconds flat on street tyres and keep it driver friendly for work to on the road.

I plan on buying a 351 4ma crank and use 302 rods with flat top pistons and 4v vales in the 2v heads and a 2.5 inch dual exhust system with turbo mufflers back by a 2500 stall converter on my c4 tranny with a trick kit and a 9' lsd diff with 3:55:1 diff ratio.

i also have 15x 8 inch globe mags on it with 235/60/15 tyres

Im aim for 450hp max from my engine rebuild would this do the trick?

Is this possible to do with the car still in street trim or am i dreaming?

If u kno anything i might have missed i would like anyone help thanks.

 

[TyreToaster]

you missed a whole lot of critical stuff to achive 11's in a car weighing 1700+kilos


sorry but your dreaming

ps 450 hp with really well set up car at that weight lucky to run mid 12's in real street trim

 

[CK351]

yeah u think so i sore one guys xc in addy and its in full street trim and all and he pulls flat 11s

i am will to speand up to $6000 on the motor as long as i am quiker then a wrx and skylines

 

[Casper]

$6000 is unlikely to get you 11's. At least not in street trim.

 

[qwikcorty]

u could buy tyretoasters bottom end he has for sale, some alloy heads and then u could do it. or put a 450hp 351 in a corty!

 

[CK351]

ok im will get a pair of 3v alloy head from chi.
but what else can u guys recomend that will get me the speed and power i need?

 

[qwikcorty]

has the xc got a gbox and diff strong enough for 11's? that would soak up some $$

 

[EBXR]

Might be better off building the car up so it is capable of running 11's over a few years.

First aim for 14's, then 13's etc.... And enjoy the sport, learning what works best for you.

How often have you raced on a drag strip???

HEAPS OF $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$

 

[CK351]

i neva raced anywhere but i kno how fast my car goes now and its all ready does 14.5 with the 302

 

[philstoj]

how do you know if you never raced?????
theres heaps of 351's that would not run a 14.5, what makes your 302 so special?
have a good read thru the forums, get a few ideas together, then do what you have to do...

 

[zc347]

3 or 4 grand stall and some better gears like 4.11's or 4.56's are going to be needed as well i think.

 

[TyreToaster]

11's is seriously fast, $6000 is not enough for a 450hp clevo unless you use s tock bottom end blow all $6000 on the top and then watch it self destruct the first time you run it, your 302 must be pretty nicley worked over to run 14.5 1/4 times (dont tell me its stock) i know what your up against becuse i own a car of your weight and size.

ps motor sold for $1300 qwik corty

 

[TyreToaster]

by the way stock wrx pulls , mid 15 1/4's with a good driver, wrx sti ( the fastest factory offering in aust) pulls 14.0 flat r33 gtst skyline would be lucky to run anywhere near a 14.5 in stock trim so in theory your car should already beat these cars as is, see where im going with this?

 

[Racer]

Lots of cam
Lots of compression
Lots of revs
Lots of convertor
Lots of gear
And big slicks

But unfortunately $6k wont even get you the driveline, let alone the engine. You may want to re-evaluate your goals.

 

[STROKEXD]

You guys being a way too negative! If an 11 sec XC was your goal to run 11's I'm sure it could be done for $6000, not the way I would do it, but it can be done. Just look at the times street/drag cars are running. Dunno maybe its different East side..

Anyone say nitrous?

 

[ebxr8240]

Now what you should have said."I want to go fairly fast at drag racing.What is rquired to go 12"s" ??? In Xc 351 or 389 clevo...A Friend of mine has run 13.1 last wednesday night at eastern creek..With T04E turbo 24 inj 8860 EMS and slicks.RPM [4800] is restricted due to inj being too small... Has 200 rwkw and has cost atleast that amount..Doing most the fabing ourselves....

 

[TyreToaster]

cant build a motor and buy nitrous components for $6000 anyway so still no

 

[Racer]

It hardly matters. 11 second flat (11.00) in a full weight XC is nearer 600hp........

 

[TTNOS8]

Even though it is not impossible to achieve what you are trying to do with your budget of $6,000, It would be stretching things a little.

A few points from your first post which would need addressing,

i wanna get it to do a 1/4 mile in 11 seconds flat on street tyres and keep it driver friendly for work to on the road.

Not gunna happen on street tyres.

I plan on buying a 351 4ma crank.

4MA will gain you no advantage in your case.

a 2.5 inch dual exhust system with turbo mufflers.

Too small exhaust for even 400HP, check other threads for exhaust recommendations

a 2500 stall converter

Probably want a higher stall than this-combined with below

9' lsd diff with 3:55:1 diff ratio

As suggested by others, probably want 4.11's or even 4.56

Im aim for 450hp max from my engine rebuild would this do the trick?

Possibly yes. Considered nitrous?

Is this possible to do with the car still in street trim or am i dreaming?

Most probably Dreaming.

Have you considered ignition, camshaft, carb, extractors, etc you will use?

You have to weigh up the whole equation to consider times you'll run. If you get a nice 400-450HP Clevo with a 100HP shot of nitrous, around a 4,500 convertor, 4.11's or even maybe 3.9's, big slicks, and a really good run down the strip, in street trim you'll get well into the 11's.

11 flat is pushin the limits. If you can get all the above for $6,000, good on ya

Good Luck anyway!
