HHP is closer to me than MMPG ( Dave weber) , yet I drove 7 hours to get the parts for my 08 Charger R/T.
Dave is patient in explaining the nuances of each project.
He doesn't do "packages" , or stages, each project is done separately, based on YOUR goals.
He was the first person in my journey to ask me what I wanted, what my goals were.
I wanted to build a mid /high 11 sec N/A 5.7 stock bottom end.
Together with Builder bill ( Paramount performance) and both Johan and then Brent at DTP for the dyne tune, they designed and built the parts, I put it together, and beat the snot out of it.
Last week it went 11.6 @ 117 MPH. it has 87k on it and when Im not driving my RAM, its my daily driver. there is one other car in my self proclaimed "class" .
If I wasn't wanting be so involved I would have gone to HHP, they have the fastest Hellcat in the world I believe.
HHP also has a lot of experience and success with the Hemi's.
In a nutshell my opinion is if you want a unique build and have definite goals, or want to discuss possibilities talk to dave.
If you would be ok with a proven package or stage then HHP might get the nod.
I would talk to both and see which one you are comfortable with.
Then again shipping costs might be cheaper from Martinsville va to you ( Bloomington ill, right?) if all other factors are equal, to you.
Agreed with the Arrington statements..from what I have learned on the forums ( lx forums) my opinion is if you take your car to them and spend an assload of $ you will get a great result.
Buying parts, consulting on a build....seems to be a crap shoot.
Good luck and post up!
