Who's running the biggest BHP on the MD321T on V-Power?
#31
are there any V's out there running 500bhp on v power other than dynamix ?
I have the RCM 500 on my 2.5 but my mapper does not think the car is running 500 - I tend to listern to Bob more than any dyno result. He also mentioned there is a noticable differnce in response between what I have and the 321T

Will be fitting a V in the next couple of weeks on my 2.5 build (see projects) and will only be running V-power (for now ), will post results when I get them but I'm hoping to get close to the magic '500bhp' which a lot of people seem to aim for (have been told I should make mid 500's torque wise ).

Currently making 410bhp/340ft lbs on a 321t @1.5bar (standard internals).

They will be a nice second hand T going soon i would imagine.
The V on the 2.5 is beautiful. If the engine (and clutch/box) integrity is good you can get more than mid 500's lb/ft torque too. Highest mine has read so far is 603 lb/ft @ 2.2 bar peak then tailing off. I am hoping to improve this shortly when I can get some time on the dyno on the full E85 fuel.

Stealthy, wasn't planning on going over 450/450 orginally (thats why I fitted the 321t a couple of months ago instead of a 321h), then I got a bit carried away , a month after fitting the 't' ended up going the 2.5 cdb route and realised that it could handle a little more than the 321t . Expensive mistake I know but at least someones going to get a cheap 321t only a couple of months old in two weeks time.
Duncan, what do your think of my fuel rails, do they look familiar , think Carl owes you a few drinks for the advertising, if I handn't seen your pics on here I would have bought Perrins.

Can anyone comment on what the MD321T is like on a 2ltr car? I'm currently running a VF35 and looking to change. How does the MD compare to the VF (lag, spool up, max boost by, etc)?
#47
I have just changed from the vf35 to the T on my 04 sti, spool up is not that much slower than the vf. I was real concerned about going for the T as everything I read was saying they weren't suited to the 2.0l. During the mapping Andy F told me he doesn't think there is any difference in spool between the H & T. Btw I kept my sti tmic don't like fmic.
I tried watching my psi3 in forth gear but the refresh rate isn't fast enough for me to see when 1bar hits although I did see 1.3 @ 3700rpm, mine peaks @ 1.6 and holds it till redline.
It might cost a good bit of money but by god am I glad I bought it!

Marcus,
Yours is the green uk99?
On sti5/6 usually find they get to 3800rpm and all hell breaks lose and they are not sluggish below 3800rpm either.
Had 504bhp on race fuel on a 2 litre with a T.. 450bhp with vpower
2.5 today was if my memory is correct 460bhp and 510lb on race fuel though.
You would probably lose 600rpm in spool from the vf35.. iirc you engine is standard tohugh so wouldn't las to on the T..
uk engine 99 engine on a H today at 385bhp at 1.4bar.. it would have made more but was holding it back for fear of lunching the box or the engine..
My own V made 491bhp at 1.65bar tailing to 1.45bar yestersday

465/540 is a cracking result. That's some serious torque !
If you have access to E85, a mix will certainly out perform Methanol, but you will use quite a bit more fuel to get the extra power. This means that you will need to make sure that you have some head room with your current fuel pump, & injectors.

Interesting statement on the fuel though, Methanol has an octane rating of 113 compared to Bio Ethanols 105. Have you tested the same mix of fuels on the same car and do you have any results to show us ?

Using BioEthanol will require less fuel than Methanol (at the same mix %) so I would be dubious over it getting better results than an equivalent mix of methanol. I have no firm data to prove or disprove which gets better results though although I have run both additives and had great results on both.
I prefer using BioEthanol from a handling, safety and availability point of view. (it smells mighty fruity too )

Assuming STi 4 heads (and headers/up pipe, if required) were fitted, then what would you expect the T to make on 97 ONLY? (my intention is to end up with a 400bhp car mapped on 97... and I'm sure the T can do it).

I wasn't really thinking of running this turbo on the car as it is (although it could be fun for a short time ). I'm looking at building a forged 2.0 or 2.1 to drop into the car next year with somewhere between 400-450bhp.
Do you know roughly how much boost and at what power/torque could the T make on my car as it is without the motor or box going pop? I presume the motor is the weak link as on a 2.0 the torque wouldn't be as high so the box could last?

Hi Simon, yes my car is the green uk99 that you've mapped three times now So your nearly at 500 now then

I presumed you would be changing the engine but wanted to make sure.. lol
probably late 300s, 1.2bar perhaps..
yes due to lower torque at that boost and spool later on 2litre the box should be okay for a bit

Out of interest how much slower spooling is the V over the T on a given setup...say a 2.5? ABout 300 rpm? Presumably its much stronger up the rev range tho.
