Will my blower combo be a dog N/A?

[IndyBlk5.0]

Parts, ported gt40 intake (tmoss) 75mm tbody, f303 cam, 64cc 180 protoplines, MAHLE forged flatops @ 8.7:1 compression ratio. and everything in sig...
Im afraid that with the compression ratio that it has it will be a dog. What do you all think?

 

[TT91]

yea, youll be lucky if it cranks over..

How much boost are you planning on throwing at her?

 

[DirtyD916]

i think it would make anice na street motor.

I'm worried about the same thing with my N/A 351w with low compression. Where does compression effect hp/tq? Low end, top end, all the way through the RPM range?

 

[IndyBlk5.0]

I plan on 10 psi... Whatever gets me to 475-500rwhp.
I just think with the lower compression ratio that it wont be any good n/a for the time being?

8.7:1 is not that low, it won't be a dog set it up and tuned it right.

Milling the heads is always an option..

tom i'm going to the bank sometime soon (when i'm not working) to get that money order... PM sent

The 8.7:1 isn't that bad at all, stock is typically 8.9-9.25:1 , and they still have decent response down low, not great power, but not bad either. Then if you factor in your increased airflow you will still make good power, a world of difference from stock.

Compression will affect overall horsepower and torque, typical results are in the 4-5% of an increase when increasing 1:1 compression. I wouldn't worry about your low compression, it will pay off when you add in your blower .

I hope your not referring to me, i told you to wait until i get my orders and find out when ill becoming home. Dont make this diffucult, i know you wanna buy my setup, but i told you i am having second thoughts. If you send money, im sending it right back to you. Thanks

No I was'nt mike, Tom is porting my lower intake for me soon. I know the situation. Like I said, I'm waiting patiently.

 

[bmo37]

will run like a truck on the street but no beast with that compression. I have close to 10:5.1 with a blower about 9lbs of boost

 

[Ranchero5.0]

Yep, gonna get beat by stock hondas with that low a compression and a F cam. Not sure how those heads flow, but I bet they hurt you hard down low if they flow too good... The only thing that'll make it feel fast is the gears and the lopy idle.

like stated if you have smaller valves that will help with the lowend and torque down low but if its some big heads than its going to be slow, ever see the rated hp for a new crate 351w with 8:25.1 compression its like 210hp.

 

[IndyBlk5.0]

2.02 vavles, i dont care if its slow. I'm just waiting to get something to wake it up, whatever that might be

It clearly says TOM there.
But since you brought it up, Its a piss poor thing to advertise stuff for sale and then get a buyer and back out.
