I want 50bhp more...(500) What's the next step?

[G_Sleigh]

Hey guys

Just after a little feedback of what the next logical upgrades would be?

I am currently running roughly 457bhp according to the map I was given with the vehicle (JetStream tuned)
So I believe its got larger intercooler, independent oil coiling system, T28 turbo's and essentially the M400 upgrade.

What's the next list of items to look at without it becoming un-drivable?
Who on here is running about 500bhp?

Probably valve springs/rods upgraded and the timing modification, then remap possibly with bigger injectors.

I assume you have an upgraded duel exhaust system.

Hey. Yea its got an upgraded exhaust system already.
That all sounds o.k.

Are injectors not a must at this stage then?
I tried to read the previous injectors thread but got to technical for me.

[Hollowpockets]

Well to get from 480 to 550(then eventually 600) a couple years back I had to upgrade from the standard M400 injectors, so I'm guessing your 3/3R injectors will be close to their max at 450.

Best confirm with Jetstream

With those upgrades you could prob see 5-520bhp if the clutch will take it, but for that little lot you'll be the guts of £2.5k ish

hard to advise without the existing spec....
Realistically Valve springs should already be done as you struggle to get much beyond 400bhp without them so check with jetstream, you should already have an upgraded clutch as thats needed for 450bhp isn, and this is also the limit for stock injectors.

the stock cast pistons are questionable at 500bhp and id be looking to fit forged ones for reliability, leave rods as they are as you can see 600bhp with them so longer ones are needed, stock cams will be fine for you (and can see 550bhp) as will your turbo's (unless they are genuine M400 T28's which won't make 500bhp without upgrading!).

prob best to speak to jetstream and find what you have and asks about the next steps

[G_Sleigh]

Hey

Thanks for the advice.

Its always good to get a few more points of view about what people would upgrade who have already been there and done it. I will speak with JetStream next week about it as its something I do want to do. If I could it for just 2.5k I would be very pleased. I was expecting more.

I'm guessing this is on top of an uprated gearbox guys? Possibly looking at this route also

[CaptainJp]

How do you tell if you have the larger injectors and if my T28 turbo's have been upgraded?

It said T28 Hybrid on the sheet from NMS.

[Hollowpockets]

Depends on how it's mapped but it will prob need gearbox done. Which is another £2000 I think.

Unless you done the upgrades yourself JP, don't assume anything until it's been checked, get it checked out but sounds like it's had the universal turbos treatment and a remap maybe with bigger injectors.

To make 500 you will need :
injectors
T28 turbos
Exhaust
Intercooler
Cam timing
Valve springs
Yellowshed remapp
To make it reliable you also need :
Uprated clutch
Uprated gearbox

I ran this for 2 years 12000 miles and 20 track days with no ipssues on std engine .
