Car is looking good, should be a great competitor this year, the badbish vs sharkbite2000 was a great video good comparision!!

 

I just got it running on the dyno - man what an engine

I was breaking it in with some pump gas 93 octane and figured WTF I would try and see how much power it could make before it started to knock badly and put the knock sensor settings on very tight

I was shocked to make 788 with ease at just touching 40 psi

This sheet is compared to my old engine with a smaller turbo wheel and back housing at 54 psi



Thanks to David Buschur For a great engine and for the inspiration to make big power on p[ump gas!

 

788 on pump?

I say camel dung.

Is that the record whp for pump gas?

 

I would say that is definitely the record.

 

That is definetely a record. Congrats Al!

 

Nice Al! We were talking about what a 42 could do on pump the other day. Throw a little meth in and that could be a wicked street combo.

 

Not a record unless the thing can actually run for more than one pull!

It seems to me it's not cylinder pressures which cause knock. Because as you step up to bigger turbos, you are able to make more and more power. And more power = more cylinder pressure?

So I can only assume it's the compressor efficiency and maybe more importantly the larger turbine housing? Perhaps exhaust back pressure is a big contributor to knock?

 

Impressive work AL.

Will you be running oxygenated or leaded in the future, or just pump ?

knock is much less an issue on robust parts that aren't stock. Backpressure doesnt really cause knock it causes preignition which can be an issue on forged parts

 

Here are some pics of the final product

I am very proud of my winter project as it went directly from its service bay to the dyno without a leak or drip







Now its time to refine all the loose ends and head to the track

 

jesus. thats not a shifter in may hand. it's my ******. haha.

 

what kind of timing at that boost on 93? EGT? AFR?

 

Are you using ARP seat bolts?

 

link??wow that is just insane power on pump,i didnt even think it was possible with a 4 cyl.thats just crazy!great setup,great power,great times to come!

 

What is that AN fitting in between the cam gears?

 

goodjob al, make me proud to be a numeros 8 owner
