Sounds goood!!!!

 

this is my new thread to follow very closely!

 

Keep watching!

 

Nice man, subscribed.

 

thanks ryan!

 

so wait, how long do you plan to run before you put heads/cams in? I'll tell you right now pulling down to do heads and cams is a super ***** so if you can find a way to do it when the engine is out!

also, look into getting a CJ twin pump hanger asap. I ran out of a single walbro with the vortech at 451 on injected's dynodynamics (which would be like 507 on dynojet) so it will probably die out in the upper 500's turbo'ed on the dynojet. If you're happy with that for now then don't worry about it.

so get that engine out and start building it!

 

I will most likely have the heads/cams when my motor is out. Im going to be getting the motor from kyle@ipp. He tqs the heads down and everything so... Ill just drop the motor in when its all said and done... I am going to go with stage 2 long block + extras like L19s etc.

Im definitely going to check out the fuel system from CJM.

But thats going to be part 2 of the build around mid summer.

 

ya, you could maybe get by with mid-upper 500's on a walbro but why waste hte dyno time and heartache and just double pump it now and have plenty of fuel for tons of power!

 

Iam definitely going with twin pumps!. Just so much stufff to buy!! ( that would be nice to have )

 

nah, cass hit 630 on single walbro with pump+meth.

Superchargers has soo much parasitic loss compared to turbos. I was maxxed as well with CJM stage2 and 600 injectors. But they will run 600 on a turbo.

 

that is very true. i think we put similar numbers on the DD with vortech and my walbro was maxed.

the meth will help out with the fuel issue a good amount. I'd rather error on the high side so that doesn't become an issue when it's already on the dyno. Dyno time isn't cheap when you have to travel and all that. a second dyno run pays for the cjm twin pump setup!

 

Congrats Vas. Hope to see you around once everything is all done and running! GL
What are your plans for the exterior and wheels?

 

Looks like a fun project!

 

thanks man!!.. yeah definitely as soon as its done im going to come out.. larry is dying to see it haha.. soon!!..

I dont wanna say anything about the exterior and wheels yet!.. ull see

 

for clarification, my walbro wasnt maxxed, my injectors were. I happened to put my twin pumps on before I sold my SC and there was zero change in IDC.
So dont mistake injector problems with fuel pump. You only need more pump if you cant hold steady fuel pressure.

800cc injectors and single walbro will support a 600hp turbo'd car. PharmD has a single pump on his vortech with 800cc injectors and was making 550DD with no fuel problems.

i hope your dyno runs arent costing 900++$ Touch up tunes should be under 200$

 

my first tune is 550.. for uprev osiris... im sure haltech etc are more.. tunes are expensive!

 

mine was definitely fuel pump. 800cc injectors on cj return fuel system. At about 7700 rpms my fuel pressure would drop from 45 down to 10. It couldn't supply the fuel.

with meth up top i could pull back fuel and be ok like pharmD did, but i was straight fuel. makes sense if you have a 20% parasitic loss of the supercharger over a turbo though. 451*1.20 is about 540 (theroetically without the loss) so it was nearing the end of the walbro. Hal says he usually sees a single walbro give up around mid 500's on his dyno with turbo'ed cars on only pumpgas.

so ya, i could pull out another 20% of power out of my single just by switching.

now that i think about it i guess hal prob wouldn't charge me that much extra for a tune after upgrading but idk. unless going to a twin pump screws up the entire fuel map.

*edit* i thought pharmD had his duned on a dynojet also....

 

What do you guys think of RC 750 or 1000cc??? I got a good deal from Kyle@ipp... Rc injectors with clips. I know there not plug and okay but I don't mind doing the work... It would save me a few $$$'s

 

Whats your EMS again?

I ran precision 1000cc's and made 769rwhp (with 3 walbro's)......granted I upped to 1200cc this year for E85

Right now I'm tuning with uprev Osiris and hpx maf... I do plan to upgrade to haltech when my motor comes . But Osiris for now
