That was with 60shot of Nitrous Wet kit and at 1.55bar (18degrees timing)

 

Without the NOS we did 608rwhp at 1.46bar (18 degrees timing). But the most amazing thing is that we are still on a stock engine. ****ing hell, how much abuse this engine can take.

We just took the car to the dyno and we start making runs, no tuning, no timing adjustments.

 

Here is the mods list:

 

JWT ECU tuned for dual intake 850c

PE 850cc injector kit

Greddy TD-05 16G

1.2 Tomei Head Gaskets

UR pulley

Custom Twin Intake

Greddy 2-row FMIC

Greddy oil cooler

Nismo adjustable FPR

Nismo Fuel Pump.

Custom Radiator

Custom exhaust

OS Gicken Twin Clutch

 

Everything else is stock. (pistons, rods, bearings, crankshaft, springs, spockets etc.)

 

Honestly i still cant believe that. I will post the dyno soon later in the evening

impressive power but that engine is going to grenade itself make no mistake!

Thats a lot of RWHP for a medium sized turbo, you got the graph ?

What amazes me the most is that this is the 3rd time we took the car to the dyno. Plenty of runs on its back. Also its been driven frequently and its been pushed a lot to its limits several times. Still runs great. Nock wood...:)

I do and i will post it in the evening cause now i am at work.

 

This is the best turbo you can get for the Z. At 5500rpms you've got full power and the feeling of having that power at that RPM range is great.

 

The car is Twin Turbo manual with a Twin Turbo AUTO engine and as far as i know the cams for AUTO are different than the MANUAL ones and therefore we get the power even faster.

Cool look forward to it :)

I think Mac will argue that snippet with you 18's or 20's are far superior.

Sounds impressive, especially running that sort of RWHP on stock internals :eek: , and speaking of Turbo's is anyone on this site using JWT 530 sport BB's? Looking to upgrade eventually and these are supposed to spool up quite fast but know I may have to do a little work in regards to the flange being I think 5 bolt instead of straightforward 4 on the more common Turbo upgrades for the ZX...Please be gentle with me I am a girlie :D

Do you have a before and after dyno chart? ie. your Z power output before the mods, using the same dyno?

 

I think you'll find there are big differences depending on which dyno you use and the operator.

 

If you haven't changed your fuel pump then your not going to see much more than 500-550HP at the engine generated, let alone at the rear wheels. Aside of the fuel pump, cams are the next power restricting item.

 

1.46bar combined with 18degrees ignition timing is recipe for a melt down. Stock internals can accept alot of power although they just don't last very long when detonation starts.

 

Try another dyno and see the difference.

...Please be gentle with me I am a girlie :D

 

nice user name :eek: :x: :bow:

Just a small difference ;)

i thought the fuel pump was good for 600+ bhp??

 

Best ask MAC that one :x:

 

Steve

Wow! Nice figures. :bow: Proper mapping makes a big difference to what power internals can take, I think a lot of people forget this when their 400BHP engine goes bang and they blame standard pistons etc.

You can see a dyno chart from the second time at the dyno (same dyno)

at http://www.cyprusracingcars.com - featured cars - blue 300ZX.

 

Also when we used NOS we also used 110 Racing Fuel for safety reasons.

Basically we wanted to see how far this stock engine can go. We wanted to run more boost but the AIR/FUEL ratio was a bit lean so we didnt want to risk it any more.

To add on that: Racing gas is used in most cases if you are planning to run more boost and if you are planning to do more aggressive tuning. We just throw the racing gas into the gas tank and hit the NOS button :) . We didnt adjust the timing or the fuel maps. We used racing gas just for safety reasons, to avoid detonation. And to tell you the truth when we hit the NOS button the mixture became lean between 5000-6200 RPMS. Somewhere around 13.4 or something and that was due to the fact that we need larger fuel injectors for the NOS kit. Without NOS we used 98 octane unleaded gas from the petrol station and we were getting good 12.something AIR/FUEL ratio.

Very impressive m8. It's great to see someone testing a standard engine to its limits, will be interesting to see what you can take it to.

Impressive figures bud. Nice zed too. :bow:

yep, i agree with you on that one shrimpster!!!

ask JD's Z he was running them

i thought the fuel pump was good for 600+ bhp??

 

US BHP maybe
