One second..

Recommended Posts

Hi all,

 

I'm probably going to get shot down in flames but.. :)

 

I have a (basically) stock jspec RZ auto. With a budget in mind, what would be the cheapest and easiest way to remove ~a second or so off the 0-60 time?

 

If you have any ideas about prices, I'd like to know that too.

 

Would it void my JIC warranty? :) I'm assuming others from here have the warranty from there, I don't know if it allows for modifications..

 

And if any of the traders on here would like to quote directly for the job, please pm or email me.

 

Thanks!

one sec off 0-60mph........i don't think this is possible for reasonable money.

 

There is less than 1sec between a standard tt and moderately modded tt over 1/4 mile (eg my old standard tt 13.875 Matt H's old auto just under 13 secs), so shaving a sec from the 0-60 is gonna be tough i would think.

 

Doubt ( but am prepared to be proven wrong) that leon's, christians etc would be a sec quicker over 0-60

Hrm.

 

A friend is telling me that by fitting a cold air intake and a new exhaust from the dump pipe to the tip, increase the boost to the max. possible without changing the intercooler would do it fairly cheaply.

 

I don't know what he knows about Supras, and I know I know nothing :)

 

What do others think?

What about a 'Max Power' AND a 'Fast Car' sticker? Should put you in the low 4's... ;)

 

I dont think knocking a second off 0-60 is possible without major spending and some drag radials. RLTC will help get the power down and a lot of practice launching would be an idea.

 

The Supra doesnt really find its feet until 40+mph, so 0-60 is not really a good reflection of its performance.

I've got a JIC warrenty and when I asked about mods and what it would do to the warrenty they said that any mods wouldn't be covered but standard parts would be. Best checking with them though ( as I didn't go into what happens when a non standard part causes a standard part to fail )

There are cheap 'BPU' (search) mods that will give very noticeable improvements in the cars performance if increased power is your goal, but not improving other areas concerning fueling and cooling i.e. making do with a poor IC (not saying yours is but it could be) etc can lead to engine meltdown (literally).

There are some nasty examples of the potential problems on the site.

I would advise searching and reading as many threads as possible.

 

Possibly helpful 'Keywords'

 

Boost gauge, boost controller, restrictor rings, fuel cut, decat, high stall, fuel pump

That will always be the best bang for buck in improving your 0 - 60 times.

Hrm, you mean I'm going to have to learn to drive?! Dammit :)

 

Cheers for all your thoughts :) I figured it probably wasn't possible to do cheaply (or I'm sure more people at the meet last weekend would've modded their car), but hey - worth a shot :)

 

My main reasoning for wanting to do it is not so I can actually increase my 0-60 times, I don't intend on racing.. but a friend of mine has a TVR Griffith 500 HC, and I'd like to feel some of the raw 'oomph' you feel out of that when I put my foot down in the Supra :)

 

Granted, though, the Griff 500's 0-60 times would slaughter a stock Supra's (it's 3.68s on the one I'm referring to, having been modded a bit) :)

 

Btw, I was thinking roughly 1000-1500 pounds to do this, figured I could get a good few bits replaced with that. Ho hum. :looney:

 

Thanks

Please don't think i was being totally sarcastic (unusual i know!) with my response.

 

It's well known that the weakest link in any car tends to be the driver rather than it's technical performance. This is more so on a track, but even on the strip practice will help immensely. Also we all know that launching the Supra to the best of it's capability is no easy task.

Oh, not at all :) I know I'm not a drag strip driver, I am better at speed manouvering rather than just flooring it from a green light. I've never really tried drag racing, I enjoy nice driving more than just accelerating as fast as I can.

 

By the same token, I was kind of hoping if there was something I could do to strip a second off the 0-60 time, it would be of benefit in the 70-120 margin too (ie, overtaking) :)

 

Ho hum :)

 

cheers

Trade your Supe in for a Caterham.

 

Course you'd spend the next few years picking flies out of your teeth...

Bleed valve for about £50, FCD for about £70.... that should get you on your way. Boost upto 1.3 ish and you'll probably be close to getting a second off...... turbo life will shorten though :eek:

That'd be 0-60 in 2.7sec according to a quick rough calculation on the back of a fag packet. Bragging rights wouldn't last long though, dependent on the height of the cliff.

I wonder if that'd beat a proper bike.. probably not, more wind resistance in the Supra, the bike would fall a fraction faster.

 

boo :)

Power to weight is the problem, getting all that mass of the MKIV moving takes a lot of torque. TVR's weigh as much as an egg box so they always going to be very quick off the mark. But they have to say running long enough to achieve a quick 0-60.;) Reliability is often an issue. (I have a friendd who services them, very often.) A well maintained MKIV will go forever, well at least 300,000, with out much required.

 

It all depends what you want out of the car, mid range on a lightly mod MKIV is pretty stunning. If you want sub 4, 0-60’s get another car or re-mortgage the house.

if u wanna spend money, the best off the line mods have gotta b higher stall TC and cats out with powerbraking. i reckon that'll come close to a second off a bog standard start and feel quite aggressive from the passenger seat.
