i have a 99 type r which has print out at 350bhp at a bar boost, mods are standard vf turbo, yellow injectors, front mount, full mongoose system,uprated fuel pump, and not sure about ecu?

need to know what mods on top of what i have or what upgrades i need for around 400-450bhp?

any help will be great

Your car is never producing 350bhp @ 1bar on any standard VF turbo.

My very highly modded 99 sti 5 engine (same as yours) managed 360 @ 1.6bar peak on a VF28.

I'd suggest taking your car to another dyno for a comparison figure. I think you'll find there'll be quite a large discrepancy!!!

very true. get it on a dyno dynamics or or a dastek. where did you go power engineering?

i have pages and pages of printouts and runs etc by scooby clinic, not sure what boost was when taken there as only had for a couple of months, but pulls on my mates wrx which is running at 1.8bar at 396bhp, whilst mine is running a bar????

Sorry mate but you're dreaming. Sounds like your mate is talking rubbish too.
At best, let's say your on the VF28 turbo at 1 bar you'll be lucky to break 300bhp.

You're probably quicker off the mark than your mate because of the type R gearing and the fact if he's running a turbo big enough to push 1.8 bar without ****ting itself then he probably hasn't even spooled up yet. Try keeping with him on a decent run if he's running 396bhp

But back to the original point there's no VF turbo that will deliver 350bhp @ 1bar

^^^ What he said^^^

For a genuine and reliable 450, probably best to go 2.5 route. you're looking at 10k+ to do it properly.

You could make the late 300s with your car with MUCH less expenditure.

I'm running a VF28 at 1.4 Bar and pushing just under 325BHP

Im running 1.7 bar and making 440bhp

1.7bar on a VF28, you are cheating Banny!

could it be i have more mods then i though

iTrader: (22)

I made 452bhp a 1.4 bar (not a VF)but that's not the point.

There's no way the original posters car is making 350 bhp @ just over 1bar on ANY standard VF series turbo. you'd be lucky to make that at 1.5bar never mind 1 bar

yellow injectors = 440cc
best I managed on yellows was 330bhp safe or pushing them for 340bhp, that was with increased pressure as well and a regulator which you havent listed.

lol, not the responses you wanted Im guessing

RB5Caterham

Give him a break guys, at least he's not coming on here and being arsey and arrogant about what he think's he's cars making, some have in the past.

He's just going by what the Dyno Printout is showing him, whether its right or wrong is another matter but the replies will show him that perhaps they are not.

Lets make Friday a Special Day for someone....

Well said that man

RB5Caterham

Going back to his original question, bigger injectors, tubular headers, MD321H and remap should see you on the right side of 400.

Oh running a little bit more boost too...

iTrader: (4)

thanks RB5Caterham somone finally answered my question, im not trying to bulls**t or brag, but i have been up against cars the same power , and seem to out perform them , but how can the printouts be wrong from a well known tuner?

Going 4 400bhp

iTrader: (2)

All so to point out 450 bhp dose not have to cost you 10K, You can do it for less, I'm just about to start i build and will put up all the parts i get a prices very soon so people can see it dose not cost as much as you may think.

You will need a new gearbox dou, I blow up a RA box with a TD04H at about 320bhp.

Look out for my thread very soon

damotypeR

iTrader: (4)

thanks mate i supose its all to do with the quality of the build, also where can i get a MD321H turbo? also what make of headers? and will 740cc injectors be up to the job

Going 4 400bhp

iTrader: (2)

Wasting money already

That turbo is a lot of money and a FP Green or red will do the same job for less £££. Area 52 Autosport On-line shop

Headers, Im using the one's i have on the car what have been ported and have been told that is good enough for the job.

740's, check out the for sale section or there about £350 new i think

i have seen a garret gt30r turbo on scooby clinic for £799 or is that more then i need for around 400brake??

i have so many things i want to do but dont know where to start lol

Power Junkie

Have a look at My car. it is also a 99 Type R, With the Vf28 i had 330bhp, but now with the MD321H i have around 400, i have just put a 3" system on so wont know until the map tweek on the 15th. A Type R is Very rapid at 400 and that costs allot less than 450.

iTrader: (15)

gt30r will require up and down pipes, racegate and will be good for 520bhp roughly, its a full gt series garrett turbo.
you have to ask why you want 400 brake.
you will pull length on a similarly powered car because the typeR gearing is so short, you will lose out at top speed though.

thats another thing lol im not sure what box it has as my dccd does not work, but is good for 140+ in 4th, can i tell what box it is by the code by the starter motor?

Power Junkie

iTrader: (1)

Yes tell us the code of the box. Mine does about 100 in 4th
