I have a 3.05" pulley.

[haggi961]

I think 450 is achievable with water / meth And a 2.8 pulley On a 2.2 ecotec with good porting ls4 and big air filter and bigger than 630 injectors And possibly a higher capacity pump Not my personal aim but I do have a 2.8 pulley sat in garage Which will find its way on To the car one day for sure My personal challenge now is to keep the car over 350 hp for a full session on my 3.1 pulley Using water only And from then on who knows But keeping hold of the power is essential for me

My aim when i get my car back is to lower pulley and go for the 450 hp at some point with the extras to get there.

450 new liners I am afraid ££££

[NickB787]

May have a problem (I hope) with my scanner which ones are people using now? Are the Bluetooth ones any good?

Is Obd tuner connecting ok nick ? I still use all wired products rather than Bluetooth Scanguage or obdtuner for me

[NickB787]

So wired it is then will order one, any links to a reliable source?

[vocky]

I have a few OBD cables if you need one today Nick

[NickB787]

Thanks for the offer Neil, I won't be working on it today though., just annoying

Liners are rated to 750 bhp so there's still loads of room for more power aslong as the inlet temps are maintained.

[NickB787]

Are was always under the impression that 400 was the limit, looks like I have a new goal now😀

[techieboy]

So, do you need a hand with anything today Nick? Can be at your front door in 20 seconds.....

What's the source for the 750?

I think Nick is referring to the L61 GM buildbook sheet.

The build book put the engine into categories from stock to 250hp then 250hp to 400hp and 400hp to 600hp so on. So they put the liners in the 400 category which is where people get the 400 hp from. It's amazing that any components whatsoever designed for a stock 140-hp 2.2-liter Ecotec would survive on an extreme powerplant making more than six times the power. However, the stock Ecotec block and main/girdle structure did survive to 750 hp, as did the stock sleeves. The stock bearings also survived.

Why are you not aiming for higher then? 600 should be your new target. 😅

will need a wheelie bar 😂 Reading the build of the engine thread I think are next problems will be head gasket and coil pack 🙈😀

[siztenboots]

is that 400 , 450 or 600 miles the target?

That poor lsj manifold is going to get more abuse then a seventies Jim'll Fix It audience.

Also another thing to consider is that they banged loads of nitros through the engine and did 8-10 full-power dyno "Sprints" from peak torque through maximum power in 50 rpm steps, concluding with at least six seconds at full power, for a total of at least 20 very hard seconds. Then the parts where sent to a lab for forensic analysis.

How will it be when water injection will be keeping it cool and doing its job that the manifold will be running better then when it was running standard bhp it was designed for 😀

Good progress today, Matt appeared after 20 seconds as promised, starting problems seemed to have been a combination of old fuel and the fact the secondary fuel pump was not working, sorted that am glad to say. My obd reader kept falling over but scangauge connected ok so hop it's the readers fault. Will try tomorrow with Matts
