fastest stock twins...what other engine mods do you have?

[steve77964]

would like to know peoples set ups when running the stock twins etc

[BlitzBoy]

Fastest Stock twins uk record was set by sdminus, he ran stock twins sequentially at 12 second dead on the quarter mile, a lot of singles cant match this. He ran on stock ports, he had uprated fuelling mods,Apexi PFC, he ran the Aquamist HFS5 kit and tuned it on 50:50 methonal.
He had approx over 380 at the wheels

[steve77964]

what about the cooling setup and induction kit?

[BlitzBoy]

He had a Front mounted intercooler and uprated rad, I think he had the blitz kit but cant be sure on that

[shaunwil]

Plus he had done huge mods and testing on getting good launches on the strip. He has a great deal of knowledge on the water injection side of his setup.

Very nice guy that I used to chat to a lot about getting quicker on the stock twins.

No it was a trust/Greddy fmic, an aftermarket rad plus Apexi style induction. But he did mount the radiator slightly over to the left and also the FMIC and put some custom ducting to the induction kit.

His car was insane !! He took me out on a number of occasions and I was just blown away by how it performed. Plus he got my respect because a lot of what he did was self taught.

Helped me out a number of times with my car, he does lurk here sometimes (cant remember the id now) but is more into Go Karting which he is doing pretty well at.

[civicboy28]

what karting does he do?

[gmogle]

what karting does he do?

Not sure mate.

Scott is not a member here now, so you wont catch him here. he is still very much in to his karts, is very knowledgeable with WI.
He is helping with a cool project at the moment on WI.

[marco]

gary do you have contact details for him? i am currently part way through designing my WI system, and in discussion with richard at aquamist about it, but it might be quicker to talk to someone with RX knowledge! I am starting to think that the more peoples input i have on this the better!

Anyone else got some repectable power on twins? Also what boost was the fella running? I guess it must have been pretty high, esp. w/water inj.

[BenLewisMav]

Also I was wondering, does running the twin sequentially or non-sequentially have any outcome to the final power?  I imagined that running both turbos up top would yeald far higher power figures, but I personally prefer that low down kick...

[BlitzBoy]

Ben, Scott ran them sequentially at just over a BAR , also Warthog ran them seqentially and he attained 389 rwhp

[skybusr34]

im pretty sure it does not raise top end power, ust alters the delivery

[chrisJDM]

Warthog was running his at 1.2bar boost, went through a couple of twin turbo packs i think.  That is really pushing it thou you wont get anymore then that and expect to replace them a few times aswell.
Most run a Front Mount intercooler.

Mine was running quite good power on stock twins although i never had it dyno\'d, here is the spec:

Rebuild and Street Ported Engine
Apexi Power FC and Commander, mapped to 1.1bar
GReddy Induction Kit
Bailey Venturi Dump Valve
GReddy Profec B Boost Controller
GReddy Front Mounted Intercooler with hard pipes
1600cc uprated secondary injectors
Uprated Nippondenso Fuel Pump
Uprated Fuel Rail
Uprated Downpipe, silenced de-cat and Apexi Back Box
Battery Relocated to Boot
Aluminium AST
Engine Torque Damper
Koyo Performance Radiator
Air Pump Removed
Air Con Removed

The only thing i was missing really was water injection.
