they look better than standard inlet if that helps lol! they give better distribution to all 4 cylinders apparently but the standard ones are adequate for that power level

There's no harm in it and at least if you won't more power it's already there!

Stage 2 used to be 300bhp years ago

Stage 1 standard injectors 270
Stage 2 light green injectors 300
Stage 3 dark green injectors 330

They say a standard 2wd is good enough for that power , if not a 4x4 one and a small turbo good for 500bhp .

I prefer the look of the hart and I think I would put it on

Hart isn't a straight forward fit, I'd stick with a standard plenum.

I cant see any reason how the one that flows better could in anyway be a bad thing ... it may not be needed at that power level but it must drive better I would think

there could, due to size be a notable difference in "lag" the same as the difference between fitting a 500 size cooler vs standard cooler. most probably only notable on a rr printout and not in real world terms

i would have thought tho may be wrong that the additional more equal flow would give benefits in mid range torque??? probbly wrong tho lol

I was thinking of replacing my rs500 inlet with a hart at 500hp but still don't know if there's a benefit at 500hp? I don't like the look of the hart compared to the 500 inlet!!

at higher (500+) levels there is definatley a noticable increase with the hart, im sure rod at his level saw around 40bhp from manifold and a map tweak iirc

what I have seen about these inlets its normally 15bhp upwards ... not bad from a money for the extra bhp point of view

I would go for a late escos inlet and it keeps the bay looking stock as a result. I have put all the cossie types side by side and its by far the best for flow, even better with a bit of a dremel clean up inside of the casting

I went from a ST Escos inlet to an A/S one and noticed no difference in spool up.

James - I'd fit it, looks super trick.

Also, Not sure if you bought the engine fully complete, but it was already fitted with a 4 x 4 inlet and also the inlet was also ported to match the head that Karl Norris did. All the inlet manifold is beautifully ported, it took me days to do. I also took it to my local technical college where they checked that all the ports were equal on an air flow bench. On the third attempt I got all four flowing perfectly even.

hi jim

they do look sexy

i have the full engine with the ported trumpet section ,but i will probably have to take out the t4 cams you and karl had specced for the engine at the time as they will be overkill for 380bhp

ps i will be updating the build threas in the next few days lol

the thing is glenn i have to have it mapped in the uk probably so have to go with one and stick with it mate

James wasn't your engine built and specced for a T4, if so why not stick the T4 and Hart inlet on and unleash the horses

I have installed a Hart (autospecialist type) inlet manifold on my engine (stage 3 and T35), I also have installed an AB07 inlet camshaft to reduce the lag that this manifold creates, I saw a mid range power gain but know my engine creates power up to the rev limiter.
I believe that you can release the maximum bhp at this stage with this manifold but you must install an inlet manifold to help it

steve probably because i want to keep matching numbers lol

i dont want to tempt faith with the 205 block mate ,380/400 bhp will be loads for a road car

I don't have a GT35 but an Escort's Rs Cosworth big turbo T35 (T34.63), I'm planning to see with my current setup 400+hp from my current setup (AB07, T34.63, Hart inlet manifold, 2wd exhaust manifold, 60mm Rs500 type i/c)

it is tuned to work at 1,55bar (mid range) and at high rpm (higher than 6000) at 1,45 on a Dyno Dynamic produced 388hp (crank)

My next target is 420+hp from a T35 at 1,55 bar at high rpm (I know that it's difficult to do it, but I will try)
