If i remember correctly, with my 1200ax set-up, I made 315-325 on 93 and I am at 350whp+ on e85-e100...with full 1.75" primaries and 3" full exhaust, ported head and a bunch of cooling mods. With more fuel there is a potential for 370whp+ with agressive tune. Putting a bigger blower on is almost pointless without a ported head its a night and day difference in power potential for the twinscrew especially with the 1.6

 

how do you guys think this will do on a car with ported and polished head and cams??

 

Easy 400+ with the 1.6L ported head + other mods and lots of fuel! I went over 400+whp with the 1.2 and some juice.

 

any graphs? not that i dont believe you but id love to see the tourque curve on that bitch with the twinscrew and juice!

 

Can you post your dyno sheet please?

 

pretty much what is expected, same as the tvs

 

thats with the 1200ax the lysholm there putting on is the 1600

 

no use responding to him

 

this! His only response (summarized) would be "get a turbo, it makes more power. I dont care if you want a SC with no boost lag. Get a turbo. Turbo turbo turbo."

 

they can put a 10 liter blower on there, without the additional work and parts to help the air get in and out faster, it's not going to be much better, if any at all.

 

a proper turbo setup don't have lag, bad info.

 

Every turbo set up had lag. A good setup may have less or even close to no lag, but it still has lag. Anywho, back on topic

 

exactly. Which is why this part had been toted from the beginning as for ported head only.

 

i won't get into that debate with you because you've shown your lack of knowledge in the area plenty of times

 

yep and this is why i was gawking at the people talking about these massive gains with this thing. it's going to take an extra couple grand in parts from a stock car to do anything at all. but hell with all that money, wasn't there an m62 car with that stroker motor that made 400hp? lol

 

Yes and it reved to 9500 RPM's to make that power. That kind of power can be had on the MP62 you just need custom cams and the willingness to rev the **** out of it. Or the ***** to run the LE5 bottom end on a 2.0 head (11:1 comp ratio), e85, porting, custom cams, and such, MP62 with a 2.6 ring on that setup with a custom header should make 400 hp at 7000 rpm's rather than 9000, like the zzp stroker. Or at least thats what computer simulation tells me.

 

he dident spin it that high at the time they could only go to the stock pcm limit of 8152 now its a different i do believe i pretty sure they found a way around it

 

Yup, just have to disconnect the speed sensor.

 

if you do that the rpm multiplier dosent work they are getting a mph reading from one of the wheel bearings i dont remember which but you haave to have the rpm multiplier working

 

IIRC it was the passenger rear wheel bearing.

 

interesting... say more

 

Unfortunately my laptop that had my hp tune files and dyno charts was stolen. I am swapping my motor and tranny soon with some additional parts and will re dyno. Its my daily driver so whenever i get to it I will post some results. The torque steer is pretty serious! Throttle is very responsive with 16psi around 2000rpms. It took some time to get the kit the right from RAWS mistakes.

 

No doubt, I believe it!

@ Boominit

When we took the 1600ax out for a spin on the 3.8 pulley making 20.5 psi by 7400 rpm... it felt incredible. So much room left to pulley it down too... The 1600ax on a 3.4 pulley should have no problem hitting 400whp, on a ported head of course.

Just need to tune it smart and the stock bottom end will do just fine.

 

I'm sorry, but I have to agree with this....

No one ever wants to build the motor up correctly from the start with these larger blowers (TVS & Twinscrew options). Yes, you can make decent power on a stock block and head with some tuning knowledge & the proper octane but.... for all out power you will need to get into some engine work. If I were to purchase one of these blowers, I would build my engine first following the GM LSJ build book. Then I would slap the blower on, get it tuned, and enjoy.

 

Live life on the edge!
