How would a 20G perform on a 2.35?

Very well, ask MAXBOOST.

In my opinion the 2.5 is a fantastic fast road engine but doesn't last 5 mins as a race engine at 600+hp due to the physics of the engine design, the cylinder walls are far too thin to handle 600+bhp (that's OVER 150hp per cylinder (from 625cc Shocked ) for any length of time and eventually split.

Strengtheners can be fitted that will most likely hold together in a road engine but given the high pressures and temperatures of a race engine and its a ticking time bomb, not what you need if you want to be competitive.

The 2.35 is the best of both worlds using a 2.2 CDB (closed deck block) and a 2.5 crank, this gives the largest cc engine available with a very strong block that won't split at high pressures.

If the race boys could get a reliable 2.5cc engine at 600+ believe me they would use it!

All IMHO Wink

2.2 CDB-

2.5 semi CDB-

Yip gotta agree the 20g is well suited to the 2.35, very little lag & pulls right through the rev range not taken it past 7900rpm though. lol!

The power delivery of the two engines is totally different, the 2.5ltr has more torque wich fools you into thinking its a faster car whereas the 2.35ltr delivers the power smoother and keeps pulling so although it feels slower its actually the quicker car.

The 2.5ltr on a gt35r runs out of puff at around 6000rpm and its quite noticeable whereas on the 2.35ltr the gt35r seems to keep pulling and it may explain why I have hit the limiter a few times Smile


Also on full chat on drag and track the 2.5ltr will see around 100/110 oil temps where as I have never seen over 90 on the 2.35ltr.

do you get the same results from de-stroking a 2.5 as up stroking a 2.2?

what power did your 2.5 make when it maxed out a gt35 at 6k Shocked

am confused here.

just wish a had more time on me hands to do me homework Rolling Eyes


anyway a can see where jonny is coming from using the 2.2 block due to the strength ov it.

but why use a 2.5 block and take it down to 2.35 confused

and remember we talking about cars what are going t get used on the road more than the track..

well i am sticking with what i would prefer for a high powered "road car"

and 2.5 would be my choice

everyone to there own ehh ???

500bhp+ can crack the cylinder walls at the top of the block on a 2.5 if not strengthened-

I am sure Steve told me today he also had this problem with his old 2.5 block.

Well I have had a nice little drive to Swindon to see Bob Rawle to get the car mapped, with all the new changes. wow wow wow wow

Bob spent 4 hours changing alll the settings with Race Rom and has had to put in a shit load more fuel at the top end which you can really feel.

I am hoping to get the car on the rollers next week before NBO, to see what improvement the changes have made.

Phil, it will not do 600 on normal fuel, but will defo with a 10% mix.

Its running 93% duty on 800cc injectors, which I am told is about 585bhp and that is on tescos best.

I am looking at getting the wheel changed to a billet type which then might release another 30hp or so as that is whats happening with other turbos that are getting modified. So you never know it might make it on normal fuel.
